We respire to use the oxygen, to oxidise our food and release energy. This is similar like burning but a slower process. it also needs respiratory enzymes .Respiration is a slower process than burning and energy released can be stored for later use.

(2+N)×12=60
2 (12) + 12N = 60
24 + 12 N = 60
12N = 60 - 24
12N = 36
N = 36/12
N = 3

365+(224-734)+14
= 365+( -510)+14
= 365 - 510 + 14
= 365 - 496
= - 131

Sea Waves
The up and down movements of water in the sea are known as sea waves. The lower part is called wave trough whereas, the upper part of the wave is called wave crest. The distance between two adjacent crests is the wavelength and the vertical distance between the crest and the trough is the wave height.

P waves, or Primary waves are the first waves to hit the seismographs when an earthquake strikes. They are longitudinal waves which means that the direction of motion and propagation are the same.
S waves, also called secondary waves and shear waves, are the second waves to hit the seismographs. They are transverse waves, which means that the motion is perpendicular to the direction of wave propagation. S waves can only travel through solids and scientists have been successful to map the interior of the earth by studying the routes of these waves.
Surface waves are those waves that travel on the surface of the earth. The destruction caused by earthquakes is primarily done by these waves.

- Earthquake waves are of two types — body waves and surface waves.
P- Waves
- P-waves are also known as the Primary waves. They are the first waves to arrive at the surface.
- The characteristics of P-waves are like sound waves. They travel through all three mediums- solid, liquid and gas.
- These waves have a tendency to vibrate parallel to the direction of wave propagation. This causes density differences in the material through which they travel.
- These waves are responsible for elongating and squeezing of material.
S- Waves
- S- Waves arrive after some time after the happening of Earthquake and they are called secondary waves.
- A significant characteristic of these S-waves is that they travel only through a solid medium.
- The direction of vibration of this S-wave is perpendicular to the direction of wave propagation, thereby creating crests and troughs in the material of their transmission.

Having a bicameral structure means having a Lower and Upper house, that mimics the structure of Lok Sabha and Rajya Sabha (Legislativ Assembly/Vidhan Sabha and Legislative Council/Vidhan Parishad) Currently the 6 states that have a bicameral structure are: Andhra Pradesh, Uttar Pradesh, Bihar, Maharashtra,Karnataka and Jammu and Kashmir. The remaining 22 states have a unicameral structure, which means they have only the Legislative Assembly and not the Legislative Council.

Smooth Muscle Tissue
-
These are non-striated, involuntary muscles controlled by the Autonomous Nervous System.
-
It stimulates the contractility of the digestive, urinary, reproductive systems, blood vessels, and airways.
-
The actin and myosin filaments are very thin and arranged randomly, hence no striations.
-
The cells are spindle-shaped with a single nucleus.

In general language arithmetic mean is same as the average of data. It is the representative value of the group of data. Suppose we are given ‘ n ‘ number of data and we need to compute the arithmetic mean, all that we need to do is just sum up all the numbers and divide it by the total numbers.
For example, take 34, 44, 56 and 78. The sum is 212. The arithmetic mean is 212 divided by four, or 53.

Sum of all of the numbers of a group, when divided by the number of items in that list is known as the Arithmetic Mean or Mean of the group. For example, the mean of the numbers 5, 7, 9 is 4 since 5+7+9 = 21 and 21 divided by 3 [there are three numbers] is 7.

Air Pressure
Air exerts pressure in all directions. The pressure exerted by air is called the air pressure, which is the thrust exerted by air per unit area. The weight of the air acting on a unit surface area is called the atmospheric pressure.
To show that air exerts pressure, take a glass and fill it with water. Cover the mouth of the glass with an index card. Now hold the card in place and invert the glass over a sink and remove your hand from the card. The card sticks to the glass. This is because air exerts pressure on the card from below to keep the card in place. Here the pressure exerted by air upwards is more than the pressure exerted by water downwards.

When heat falls on some object, a part of it is reflected, a part is absorbed and a part may be transmitted. The temperature of the object increases due to the absorbed part of the heat.
