AIIMS Cutoff 2019

The AIIMS was taken place in the online mode in two shifts. This exam was taken by almost 3 lakh students India for a total of 1027 seats in 15 AIIMS across India. The topmost preference for the candidates remains the AIIMS in New Delhi. As the exam was conducted in different shifts, the authority has adopted the normalization process in order to equate the difficulty level of the exam. Thus, based on this process, the percentile and rank were derived. To avoid any sort of tie or the bunching effect, the exam authority has decided to calculate the percentile up to seven decimal numbers.

CBSE Class 9 Science Notes Chapter 7 Diversity in Living Organisms

Facts that Matter

Diversity: This earth is full of organisms of various shapes and sizes. The largest Phylum of animal kingdom alone contains over a million species. There are varieties of plants, right from small grasses to tall Eucalyptus trees. This variety in living beings is called diversity.

Biodiversity: The variety of animals and plants living in a given geographical area is called biodiversity of that geographical area.
Need for a System of Classification: Because of the huge diversity in living beings it becomes very difficult task to study each of them one by one. To make their study easier animals and plants were categorized in groups and sub¬groups. Thus the system of classification started.

Classification by Aristotle: Aristotle classified animals according to their living environment. So he categorized them as either aquatic or terrestrial.

Drawbacks of Aristotle’s Classification: Both in sea as well as on land we can find animals and plants. Moreover, there are very small animals, like sea-horse, along with large animals, like whale. So, this was not a good basis of classification.

Basis of Classification 
(a) Presence or Absence of Nucleus in Cells
Prokaryotes: Those organisms which have cells without well defined nucleus are called prokaryotes.
Eukaryotes: Those organisms which have cells with well defined nucleus are Called eukaryotes. Presence of nucleus and membrane-bound organelles gives better efficiency to cells.

(b) Number of Cells in an Organism
Unicellular: Those organisms having single cell are termed as unicellular organisms. In them the single cell is responsible for carrying out all necessary functions to maintain life.
Multicellular: Those organisms having more than one cell are called multicellular organisms. Because of more number of cells there can be some division of labour to gain more efficiency.

(c) Mode of Nutrition
Autotrophs: Organisms producing their own food are called autotrophs. All green plants are autotrophs. They have a pigment (chlorophyll) in green parts which facilitates photosynthesis.
Heterotrophs: Organisms dependent on either plants or animals are called heterotrophs.They don’t have chlorophylls. All animals, fungi and certain bacteria and protozoa belong to this group.

(d) Level of Organisation in Body
In multicellular organisms which are small, like hydra particular group of cells are assigned a particular function. But in larger organisms, tissues group to form an organ, which in turn make organ system. For example, in human beings there are separate systems for performing specific tasks.

Even in larger plants there is separate root system for conduction of water and minerals, leaf for photosynthesis and flowers for reproduction. Based on these characters organisms can be further classified into various sub-groups.

Evolutionary Relationship or Phylogenetic Relationship
Charles Darwin wrote a book “Origin of Species’ in 1859 and gave his theories of evolution. As per his theories all organisms have evolved from unicellular organisms. Primitive body designs came early in evolutionary history leading to more complex designs. This gave rise to such a huge diversity in life forms. Because of common ancestry, all organisms are related. The closer evolutionary relation between two organisms is also one of the basis of classification of organisms.

The Hierarchy of Classification—Groups
Biologists, such as Ernst Haeckel (1894), Robert Whittaker (1959) and Carl Woese (1977) have tried to classify all living organisms into broad categories, called kingdoms.

• Whittaker’s Five Kingdom Classification:
  • Monera
  • Protista
  • Fungi
  • Plantae
  • Animalia.
• Further Levels of Classification Beyond Kingdom
  • Phylum (for animals)/Division (for plants)
  • Class
  • Order
  • Family
  • Genus
  • Species

Thus, by separating organisms on the basis of a hierarchy of characteristics into smaller and smaller groups, we arrive at the basic unit of classification, which is a ‘species’. Broadly, a species includes all organisms that are similar enough to breed and perpetuate.

• Monera
  • These organisms do not have a defined nucleus or organelles and are unicellular.
  • Cell walls present in some organisms of this group.
  • Nutrition: Autotrophic or heterotrophic
  • Examples: Bacteria and blue-green algae
• Protista
  • Unicellular eukaryotic organisms.
  • Locomotion: By Jair-like cilia or whip-like flagella for moving around in some members.
  • Nutrition: Autotrophic or heterotrophic.
  • Examples: Algae, protozoans {Plasmodium, Entamoeba)
• Fungi
  • Heterotrophic eukaryotic organisms.
  • Nutrition: Saprophytic they use decaying organic materials as food.
• Lichens: Some fungi live in a symbiotic relationship with cyanobacteria. They are called lichens. The algal part provides food and the fungal part provides minerals and substratum.
• Plantae
  • Multicellular eukaryotes with cell walls.
  • Nutrition: Autotrophs use chlorophyll for photosynthesis.
• • Animalia
  • Multicellular eukaryotes without cell walls.
  • Nutrition Heterotrophs.

Classification of Kingdom Plantae

Thallophyta or Algae: Plants that do not have well-differentiated body design fall in this group. The plants in this group are commonly called algae. These plants are predominantly aquatic. Examples are Spirogyra, Ulothrix, Cladophora and Chora.

Bryophyta: These are called the amphibians of the plant kingdom. The plant body is commonly differentiated to form stem and leaf-like structures. However, there is no specialized tissue for the conduction of water and other substances from one part of the plant body to another. Examples are moss (Funaria) and Marchantia.

Pteridophyta: The plant body is differentiated into roots, stem and leaves and has specialized tissue for the conduction of water and other substances from one part of the plant body to another. Some examples are MarsUea, ferns and horse-tails.

Gymnosperms: The plants of this group bear naked seeds and are usually perennial, evergreen and woody. Examples are pines and deodar.

Angiosperms: This word is made from two Greek words: angio means covered and sperma—means seed. The seeds develop inside an organ which is modified to become a fruit. These are also called flowering plants. Plant embryos in seeds have structures called cotyledons.

Cotyledons: Cotyledons are called ‘seed leaves’ because in many instances they emerge and become green when the seed germinates.
The angiosperms are divided into two groups on the basis of the number of cotyledons present in the seed.

• Monocotyledonous: Seeds have a single cotyledon.
• Dicotyledonous: Seeds have two cotyledons.

Classification of Kingdom Animalia: Kingdom Animalia is further classified into several following phylum. Each phylum has it own classes, sub-classes orders, families, etc.

1. Porifera
   • These are non-motile animals attached to some solid support which comprises of spicules of calcium carbonate, silica.
   • There are holes or “pores’, all over the body. These lead to a canal system that helps in circulating water throughout the body to bring in food and oxygen.
   • Animals are covered with a hard outside layer or skeleton which comprises of spicules of calcium carbonate, silica.
   • They have very minimal differentiation and division into tissues.
   • Examples: Sponges
2. Coelenterata
   • Aquatic animals.
   • There is a cavity in the body hence the name Coelenterate (coelom means cavity).
   • Body is made of two layers of cells.
   • Examples: Hydra, Jellyfish
3. Platyhelminthes
   • The body is bilaterally symmetrical, meaning that the left and the right halves of the body have the same design.
   • There are three layers of cells from which differentiated tissues can be made, which is why such animals are called triploblastic.
   • There is no true internal body cavity or coelom, in which well developed
     organs can be accommodated.
   • The body is flattened dorsiventrally, meaning from top to bottom, which is why these animals are called flatworms.
   • They are either free-living or parasitic.
   • Examples: Planaria, Liver fluke
4. Nematoda
   • Body is bilaterally symmetrical and triploblastic.
   • Body is cylindrical rather than flattened.
   • False body cavity or a pseudocoelom, is present.
   • These are very familiar as parasitic worms causing diseases, such as the worms causing elephantiasis (filarial worms) or the worms in the intestines (roundworm or pinworms).
   • Examples: Ascaris, Wucheraria
5. Annelida
   • These are bilaterally symmetrical and triploblastic.
   • True body cavity present.
   • Body is divided into many ring like segments, hence the name annelida.
   • Examples: Earthworms, Leech
6. Arthropoda
   • The largest group of animals.
   • These are bilaterally symmetrical and segmented.
   • There is an open circulatory system, and so the blood does not flow in well defined blood vessels.
   • They have jointed legs (the word ‘arthropod’ means jointed legs’).
   • Examples: Ants, Cockroach, Grasshopper, Scorpions
7. Mollusca
   • These are bilaterally symmetrical.
   • Reduced coelomic cavity.
   • The soft body is covered with a hard shell made of calcium carbonate.
   • Examples: Snails, Mussels.
8. Echinodermata
   • In Greek, echino means hedgehog, and derma means skin. Thus, these are spiny skinned organisms.
   • Exclusively free-living marine animals.
   • Triploblastic animals with coelom.
   • They have a peculiar water-driven tube system that they use for moving around.
   • Skeleton made of calcium carbonate.
   • Examples: Starfish and Sea urchins
9. Protochordata
   • These animals are bilaterally symmetrical, triploblastic and have a coelom.
   • In addition, they show a new feature of body design, namely a notochord, at least at some stages during their lives.
   • The notochord is a long rod-like support structure (chord*string) that runs along the back of the animal separating the nervous tissue from the gut. It provides a place for muscles to attach for ease of movement.
     
   • Examples: Balanoglossus, Herdemarda and Amphioxus.
10. Vertebrata
    These animals have a true vertebral column and internal skeleton, allowing a completely different distribution of muscle attachment points to be used for movement. Vertebrates are bilaterally symmetrical, triploblastic, coelomic and segmented, with complex differentiation of body tissues and organs. All chordates possess the following features:
    • Notochord
    • Dorsal nerve cord
    • Triploblastic
    • Paired gill pouches
    • Coelomate

Vertebrates are grouped into five classes:

1. Pisces
   • Body is streamlined and has fins and tail for swimming.
   • Skin is covered with scales.
   • Skeleton can be made of bone or cartilage.
   • Intake’ of oxygen is by gills.
   • Cold-blooded animals.
   • The two-chambered heart is present.
   • Examples: Fishes like Rohu, Tuna, Shark
2. Amphibia
   • They are adapted to live both on land and water.
   • Respiration is through either gills or lungs.
   • The three-chambered heart is present.
   • Examples: Frogs, Toads, Salamander
3. Reptilia
   • These are crawling animals.
   • Skin is rough and modified to withstand extreme temperatures.
   • The heart is three chambered in most, while four-chambered in crocodiles.
   • Cold-blooded animals.
   • Examples: Lizards, Turtles, Snakes
4. Aves
   • Body is covered with feathers and forelimbs are modified for flying.
   • Breathing through lungs.
   • Warms blooded animals.
   • The four-chambered heart is present.
   • Examples: Sparrow, Eagle, Crow, Parrot
5. Mammalia
   • Mammary glands are present which produce milk to nurture young ones.
   • Skin is covered with hairs and has sweat glands and sebaceous glands.
   • Warm-blooded animals with four-chambered heart.
   • Most animals are viviparous (giving birth to live young ones), some are oviparous (producing eggs).
   • Examples: Man, Horse, Kangaroo, Lion

Conventions for writing the scientific names:

1. The name of the genus begins with a capital letter.
2. The name of the species begins with a small letter.
3. When printed, the scientific name is given in italics.
4. When written by hand, the genus name and the species name have to be underlined separately.

CBSE Class 9 Science Notes Chapter 11 Work, Power and Energy

Facts that Matter

Work: When a force acts on an object and the object shows displacement, the force has done work on the object.
Two conditions need to be satisfied for work to be done:
(i) A force should act on object
(a) The object must be displaced
Work = Force x Displacement Unit of workdone = Joule = Newton x metre 1 Joule work is said to be done when 1 Newton force is applied on an object and it shows the displacement by 1 meter.

Energy
The capacity of a body to do work is called the energy of the body.
Unit of energy = Joules 1KJ = 1000 J

Forms of Energy: The various forms of energy are potential energy, kinetic energy, heat energy, chemical energy, electrical energy and light energy.

Kinetic Energy: Energy possessed by a body due to its motion. Kinetic energy of an object increases with its speed.
Kinetic energy of body moving with a certain velocity = work done on it to make it acquire that velocity

Derivation
Let an object of mass m, move with uniform velocity u, let us displace it by s, due to constant force F, acting on it

Potential Energy
The energy possessed by a body due to its position or shape is called its potential energy.
shape


Gravitational Potential Energy: (GP)
When an object is raised through a height, work is said to be done on it against gravity.
The energy possessed by such an object is called the gravitational potential energy.
GPE = work is done in raising a body from the ground to a point against gravity.
Derivation

Consider a body with mass m, raised through a height h, from the ground, Force required to raise the object = weight of object mg.
The object gains energy to the work done on it.

Work done in both the cases (i) and (ii) is same as a body is raised from position A to B, even if the path taken is different but the height attained is the same.

Mechanical Energy: The sum of kinetic energy and potential energy is called mechanical energy.

Law of Conservation of Energy:
Energy can neither be created nor destroyed, it can only be transformed from one form to another. The total energy before and after transformation remains the same.

Potential energy + Kinetic energy = Constant (Mechanical energy)
A body of mass ‘m’ is raised to height ‘h’ at A its potential energy is maximum and kinetic energy is 0 as it is stationary.
When body falls at B, h is decreasing hence potential energy decreases and V is increasing hence kinetic energy is increasing.
When the body is about to reach the ground level, h = 0, v will be maximum hence kinetic energy –> potential energy
Decrease in potential energy = Increase in kinetic energy
This shows the continual transformation of gravitational potential energy into kinetic energy.

CBSE Class 9 Science Notes Chapter 12 Sound

Facts that Matter

A sound is a form of energy which produces a sensation of hearing in our ears.

Propagation of Sound: Sound is produced by vibrating objects.

Medium: The matter or substance through which sound is transmitted is called a medium. It can be solid, liquid or gas. Air is the most common medium for sound propagation.

Wave: A wave is a disturbance that moves through a medium when the particles of the medium set neighbouring particles into motion. They in turn produce similar motion in others. The particles of the medium do not move forward themselves, but the disturbance is carried forward. This is what happens during propagation of sound in a medium, hence sound can be visualised as a wave. Sound waves are characterised by the motion of particles in the medium and are called mechanical waves.

When a vibrating object moves forward, it pushes and compresses the air in front of it creating a region of high pressure. This region is called a compression (C), as shown in following figure. This compression starts to move away from the vibrating object. When the vibrating object moves backwards, it creates a region of low pressure called rarefaction (R).

As the object moves back and forth rapidly, a series of compressions and rarefactions is created in the air. These make the sound wave that propagates through the medium. Compression is the region of high pressure and rarefaction is the region of low pressure.

Experiment to show Sound needs a medium:
Activity:

• Take and electric bell and airtight jar.
• Fit the bell inside the jar and attach to battery.
• With air still in jar ring the bell.
• Now take out air by vaccumization.
• Ring the bell again.

Observation: Sound of bell can be heard when air is inside the jar. When air is taken out then sound cannot be heard.

Conclusion: This shows that presence of medium is necessary for propagation of sound waves.

Properties of Sound Waves:

Frequency: Number of oscillations of sound waves is called its frequency. The number of peak and troughs per unit of time will give frequency. It is represented by v (nu) and its SI unit is Hertz (Hz).
Time Period: The time taken to complete one oscillation is called its time period. Its unit is second and is represented by T.

Relation of frequency and time period:
v = 1/T

Amplitude: The magnitude of the maximum disturbance in the medium on either side of the mean value is called the amplitude of the wave. It is usually represented by the letter A. Its unit is meter.

Softness or Loudness of Sound: If the amplitude is smaller then the sound will be softer and if it is larger then sound will be louder. Higher amplitude helps the sound wave is travelling faster.

Speed of sound: It is the distance which compression or a rarefaction travels per unit of time.

So, Speed = Wavelength Frequency
The speed of the sound remains almost the same for all frequencies in a given medium under the same physical condition.
Speed of Sound in Different Media at 25° C.

Reflection of Sound: Sound reflects off a surface in the same way as light reflects and follows same rules of reflection. The incident sound and the reflected sound make equal angles with the normal and all three are in the same plane.

Echo: In bigger monuments and in large empty halls you can hear reflections of your sound after you speak something. This effect is known as echo. The sensation of sound persists in our brain for 0.1 seconds, so to hear echo the time difference between original sound and reflected sound should be more than that.
As you know speed of sound in air is = 344 m/s And 344 x 0.1 = 34.4 metre
So, the minimum distance required to hear an echo from a reflecting wall or surface should be half of 34.4, means it should be 17.2 metres.

Reverberation: Repeated reflections of sound results in persistence of sound and is called reverberation.

Use of Reverberation of Sound: Following instruments use this property of sound:

1. Megaphones, Shehanais, Trumpets
2. Stethoscope
3. Curved dome of concert halls

Range of Hearing in humans:
From 20 Hz to 20000 Hz
Sounds below 20 Hz are called infrasonic.
Sounds above 20000 Hz are called ultrasonic.

CBSE Class 9 Science Notes Chapter 14 Natural Resources

Facts that Matter

Life exists on earth due to its ambient temperature, water, food and energy from the sun.

Lithosphere: The outer crust of the earth is called the lithosphere.

Hydrosphere: Sum of all water bodies is called hydrosphere.

Atmosphere: Air that covers the earth is called the atmosphere.

Biosphere: The life-supporting zone of the earth where the atmosphere, hydrosphere and lithosphere interact and make life possible is called biosphere.
It consists of biotic components-living things and abiotic components-non- living things like air, water and soil

Air: It is a mixture of many gases like oxygen, nitrogen, carbon-dioxide, water vapour and other gases.

• Nitrogen is used by plants for protein synthesis.
• Oxygen sustains life used for respiration, combustion.
• Carbon-dioxide used by plants for preparing food by photosynthesis.

Water vapour: provides moisture.

Atmosphere: Acts as a protective blanket around the earth. Maintains the temperature on the surface of earth. Winds are caused due to uneven heating of atmosphere, these winds maintains the pressure difference and causes cold and hot air, sea and land breeze, brings rain etc.

Rain: The clouds formed due to the evaporation of water condenses and precipitates as rain.

Water: Various sources of water are available i.e., surface water, underground water, snow, ice-bergs, water vapour in the atmosphere.

Use of Water

• Water is used for transportation.
• Sustain life
• Used by plants and animals for life-processes. Water available for drinking should be conserved and used wisely.

Soil: Soil is formed by a very slow process i.e., by weathering of rocks. It consists of various nutrients. Plants grow in the soil, many microbe’s homes is soil.

Varieties of soil types are available

• Sandy soil
• Loamy Soil
• Clayey Soil
• Black soil
• Red soil
• Alluvial soil
• Laterite soil.

Temperature: Temperature and light is also required for all biotic components.

Pollution: Contamination of natural sources with unwanted substances.

• Air Pollution: Air contaminated with smoke, fumes, dust, pollen grain, etc.
• Water Pollution: Water contaminated by sewage, industrial waste, excreta, chemicals, fertilizers etc.
• Soil Pollution: Soil gets contaminated with fertilizers, pesticides, garbage, chemicals etc.

Bio-geo-chemical Cycles: A constant interaction between biotic and abiotic components of the biosphere makes a system and these flow of components form a cycle called bio-geo-chemical cycle.

Water Cycle: Water from various sources evaporates, condenses and again precipitates as rain, falls on the land, flows back in the sea and river is known as water cycle.

Nitrogen Cycle:

Nitrogen from the atmosphere is fixed by the process of nitrification. Nitrification is done by nitrogen fixing bacteria e.g. Rhizobium present in soil, these compounds of nitrogen are absorbed by plants. The fixation is also done by atmosphere or industries. In atmosphere, during lightning, high temperatures and pressures created in air converts nitrogen into oxides of nitrogen, which dissolves in water forming nitric and nitrous acids and is then used by life forms.

Plants contain nitrogen in the form of proteins or other complex compounds. Plants are eaten by animals. When die bacteria present in soil act on and convert plants and animals various compounds of nitrogen into nitrites and nitrifies. Another group of bacteria convert these nitrates and nitrites into free, elemental nitrogen, this process is called denitrification.

Carbon Cycle: Carbon is present in the compound form in atmosphere ie., CO₂, carbonates in water which forms limestone.
CO₂ is taken by plants during photosynthesis to form organic compounds like glucose, carbohydrates, these plants are further eaten by animals, and decomposition gives CO₂ back to the atmosphere. Plants and animals which get buried under the earth and does not decompose form coal and petroleum respectively.
Animals and plants also release CO₂ back to the atmosphere during respiration.

Many of the formulas used in trigonometry are also found in algebra, calculus and analytic geometry. But trigonometry also has some special formulas usually found just in those discussions. A formula provides you a rule or equation that you can count on to work, every single time. Trigonometry formulas gives a relationship between particular quantities and units. The main trick to using formulas is to know what the different letters represent. In the formulas given here, you have: r (radius); d(diameter or distance); b (base or measure of a side); h (height); a, b, c (measures of sides); x, y (coordinates on a graph); m (slope); M (midpoint); h, k (horizontal and vertical distances from the center); θ (angle theta); and s (arc length). The formulas particular to trigonometry have: sin (sine), cos (cosine), and tan (tangent), although only sin is represented here.
