The bending of light while travelling from one medium to another is called refraction of light. Refraction takes place because there is a change in the velocity of light travelling from one medium to the other. But this does not truly answer reason behind the bending of the light. For example, if you are in a car and your car slows down moving in a straight road it will not necessarily take on a bent path.

The periodic table, based on the Modern Periodic Law is called the Modern Periodic Table.
Modern periodic law states that the properties of elements are a periodic function of their atomic numbers.
- The horizontal rows in the Modern Periodic Table are called periods.
- The vertical columns in the Modern Periodic Table are called groups.

Autotrophic nutrition takes place through the process of photosynthesis. Carbon dioxide, water, chlorophyll pigment, and sunlight are the necessary conditions required for autotrophic nutrition. Carbohydrates (food) and O2 are the by-products of photosynthesis.

- Photolytic decomposition is chemical reaction where photons are broken down and interacts with target molecules.
- Photolytic decomposition is also known as photolysis.
- In this reaction the reactant molecule gets decomposed into two resultant molecules or products.
- This decomposition occurs when light is supplied to reactants in the form of energy.
- The best example for photolysis reaction is lysis of water molecule to oxygen in photosynthesis.

The tiny projections that are present on the surface of the intestine that aids in digestion is the microvilli.
Microvilli or villi are "tiny projections" that are present on the surface of the "small intestine" that aids in digestion.
They have perfect anatomy that anchors to the food and helps in its absorption, they also contain enzymes such as glycosidases that break down the absorbed food aiding in easy assimilation.

The substance which speed up the reaction and remain unchanged known as catalyst.
Biological catalyst are the naturally occurring catalysts.
These catalysts are the enzymes which present inside the body and helps to break down the complex substances into simpler one.
These catalysts are pepsin, trypsin, lipase, protease and amylase which helps in the chemical digestion of food.

2.The refractive index of a medium is defined as the ratio of velocity of light in first medium to the velocity of light in that medium.
Mathematically refractive index {tex} [\eta]\ =\frac{v_{1}} { v_{2}}{/tex}
{tex}v_{1} {/tex} is the velocity of light in first medium.
{tex}v_{2}{/tex} is the velocity of light in second medium i.e the medium under consideration.
Let the first medium is space or vacuum.
Now, the velocity of light in first medium will be c where c is the velocity of light.
Now, the refractive index {tex} \eta\ =\frac{c}{v}{/tex}
v is the velocity of light in second medium i.e medium under consideration.
Now the refractive index obtained is called absolute refractive index.
Hence, the absolute refractive index of a medium is defined as the ratio of the velocity of light in air to the velocity of light in that medium.
Mathematically the absolute refractive index =
{tex} \eta\ =\frac{velocity\ of\ in\ light\ air}{velocity\ of\ light\ in\ medium}{/tex}

The amount of urine produced depends on the amount of excess water and dissolved wastes present in the body. Some other factors such as habitat of an organism and hormone such as Anti-diuretic hormone (ADH) also regulates the amount of urine produced.
