Movement in stem and roots.

Blood Capillaries.

Correct option is (3) Pellicle 

Distinction between Direct tax and Indirect tax.

Stomach – churning machine : 

(1) If we observe a flour mill, the rocks in the machine grind the wheat / rice into flour. Here everyting is machinery. 

(2) We have to use so much of energy and apparatus. 

(3) But if we observe our stomach, in the stomach there are no machines. There are no grinding rocks. 

(4) But the food that enters into it is masticated and becomes smooth paste called chyme. 

(5) The process of conversion of food to chyme is involuntary. 

(6) Each and every activity of stomach is controlled by 10^th cranial nerve of the autonomous nervous system.

Human Immuno Virus.

Fiscal deficit is an useful instrument for giving a direction to the economy because. 

I. It helps in increasing amount of capital expenditure in the economy. 

II. Government can collect more resources for meeting out its expenditures

The three main types of blood vessels in the body are arteries, veins and capillaries. 

Arteries : 

(1) Arteries carry blood away from the heart to body parts. 

(2) Arteries carry oxygenated blood, except pulmonary artery, which carries blood from the heart to the lungs. 

Veins : 

(1) Veins carry blood from body organs to heart. 

(2) Veins carry deoxygenated blood, except pulmonary vein, which carries blood from the lungs to the heart. 

Capillaries : 

(1) These are spread throughout all the tissues. 

(2) The capillaries are the smallest blood vessels, which connect arteries with veins. 

(3) The walls of capillaries are made of single layer cells. They act as the sites of exchange of substances within the cell.

Balance of trade is related to only visible items. Difference between the value of total visible exports and imports of a country is called ‘Balance of Trade’ of that country. Visible items include physical goods as machine, cloth, cement, e.t.c 

Balance of Trade = [export of visible items] - [Import of visible Items]

I will give the following suggestions to farmers to reduce the denature of soil. 

(1) Crop rotation method : It replenishes the fertility of soil, annually crop rotation method is good.

(2) Less usage of insecticides and pesticides : Usage of pesticides and insecticides only upto the required level. 

(3) Decrease the more usage of artificial fertilizers : Try to decrease the more usage of artificial fertilizers, implementing organic family wherever suitable. 

(4) Encourage biological control methods : Biological control methods to kill the microbes, pathogens which cause crop diseases. This retain the soil from denaturing.

(5) Encourage the farmers to grow legume family plants to enrich the soil with nitrogenous compounds. 

(6) Advise the farmers to add the plants like Pachirotta, jilledu etc ., to the soil. So that soil fertility increases naturally.

(i) The CO₂ released from our body during respiration has raised the % of CO₂ in exhaled air.

(ii)Nitrogen has no role in our respiration. So there is no change in the percentage of nitrogen.

(i) Peristalsis.

(ii) Long tube like structure.

(iii) Mucus helps the food to slide down easily.

(iv) Pharynx and stomach.

The pumping device heart has to perform only circulation of bodily fluids in the body.

Nitrogen has no role in our respiration. So there is no change in the percentage of nitrogen.

The weight of the body is inversely proportional to the rate of heart beat. That means more weight of the body of organism, the less rate of heart beat. 

Less weight of the body of organism, the more rate of heart beat.

In order to supply blood to far end of the body parts heart exerts more pressure. The time taken for circulation of blood from heart to body parts and body parts is more. Hence heart beat less in the animals with more weight.

(1) Plants can get rid of excess water by a process called transpiration and guttation. 

(2) Waste products may be stored in leaves, bark and fruits. When these dead leaves, bark and ripe fruits fall off from the tree then waste products in them are eliminated.

(3) In some plants the wastes get stored in the fruits in the form of solid bodies called Raphides. 

Eg : Kiwi fruit, Agave, Spinach etc. 

(4) Several compounds are synthesized by the plants for their own use especially for defence. 

(5) Several plants produce chemicals and store them in their roots, leaves and seeds for protecting them against herbivores. 

(6) Most of the chemicals are unpalatable to taste and hence, herbivores usually do not prefer to eat such plants. 

(7) Some of the chemicals are toxic and may even kill the animal that eats them.

The time taken for circulation of blood from heart to body parts and body parts to heart is less. Therefore the rate heart beat is more in the animals with less weight. 

The following features are observed after dissecting the specimen of kidney : 

External features : 

(1) Colour of kidney, 

(2) Shape, 

(3) All the external parts. 

Internal features : 

(1) The colour and texture of inner side of the kidney. 

(2) The shape and structure of inner side. 

Procedure : 

– First the kidney is washed until all the blood is drained from it. 

– It is kept in the tray and observed all the external features carefully. 

A longitudinal section is taken with the help of sharp blade. 

After dissecting, internal parts are also observed and noted down all the features.

Newly born infants have more rate of heart beat.

In youth or adults the rate of heart beat is less.

(a) Admire and hire are the rhyming words. 

(b) The second line means there are two categories of athletes. The first play just for pleasure. The second category is players who are hired by corporate to play the big leagues or tournaments

We call भगिनी for sister in sanskrit.

Some important translations in sanskrit are:

In league-cum knockout tournament, all the teams play league matches in their respective pools. Either take out best team from each pool or take out best two teams from each pool. Now the best 4 or 8 (depends on scheme or number of teams) teams are given knockout fixtures and the winner is decided.

Sports nutrition  

It is the study and practice of nutrition and diet as it relates to athletic performance. It is concerned with the type and quantity of fluid and food taken by an athlete, and deals with nutrients such as vitamins, minerals, and organic substances such as carbohydrates, proteins and fats.

When we have less time, less manpower and modified facilities, we prefer to have knock out tournaments than round robin. There will be economy also.

a. Organization for Economic Co-operation and Development

The particle in one dimensional potential well

∴ V = 0 for 0 < x < L

V = ∞ for x ≤ 0 and x ≥ L

The particle present in a box so outside wave function Ψ is zero.

Ψ = 0 for x ≤ 0  x ≥ L

Schrodinger's equation time independent

\(\frac{∂^2\psi}{∂x^2}+\frac{2m}{h^2}\) (E - V) Ψ = 0

one dimensional V = 0

\(\frac{∂^2\psi}{∂x^2}+\frac{2m}{h^2}\) (E) Ψ = 0

Let the factor 2m/h² E = k² then

\(\frac{∂^2\psi}{∂x^2}\) + k² Ψ = 0  ...(1)

then general solution of equation (1), we get

Ψ = A sin kx + B cos kx

To calculate the total overall capacitance of a number of capacitors connected in this way you add up the individual capacitances using the following formula: C Total = C₁ + C₂ + C₃ .

Given

E = 3 x 10⁵ v/m

E₀ = 1.0 x 10⁵ v/m

Dielectric constant

K = E/E₀

K =  \(\frac{3\times10^5}{1\times10^5}\)

K = 3

\(\because\) E = \(\frac{\sigma}{\varepsilon_0}\)

σ = E \(\varepsilon_0\) 

σ = 3 x 10⁵ x 8.85 x 10^-12

σ = 26.55 x 10^-7

induced charged

σ induced = σ\(\frac{(k-1)}{(k)}\)

σ induced = 26.55 x 10^-7 x 2/3

σ induced = 1.77 x 10^-6 c/m²

option(d)

Doping is the addition of impurities to a semiconductor.  Due to this, electrons are added to conduction band. This increase the electrical conductivity.
When group V elements such as phosphorous and arsenic are doped in group IV elements (Si or Ge), n-type of semiconductor is obtained. The electrical conduction is due to extra negative charges due to extra electrons of the impurity.
When group III elements such as boron and gallium are doped in group IV elements (Si or Ge), p-type of semiconductor is obtained. The electrical conduction is due to extra positive charges due to electron holes of the impurity.

The French Revolution led to the transfer of sovereignty from the monarchy to a body of French citizens. It proclaimed that it was the people who would henceforth constitute the nation and shape its destiny.
