Digestion process starts from the mouth where salivary glands are present. Salivary glands produces amlyoses .So amylase is the first enzyme to mix with food. The saliva secreted by the salivary glands in mouth contains this enzyme that breaks down starch.

First enzyme that digests food in alimentary canal is amylase. Digestion of food starts in the mouth itself when salivary amylase hydrolyzes the starch in the ingested food particle. It is present in mouth and is secreted by salivary glands. It acts on starch.

he SMALL INTESTINE is the largest and longest part of the alimentary canal.
Small intestine is the longest part of the alimentary canal because it is the main organ of absorption and digestion of food. The surface area of the small intestine gets increased because of the presence of villi which gives food plenty of time to break down properly.

Refractive Index
- The extent of the change in direction that takes place in a given pair of media is expressed in terms of the refractive index.
- It turns out that light propagates with different speeds in different media.
- The value of the refractive index for a given pair of media depends upon the speed of light in the two media.
n21 = Speed of light in medium 1 /Speed of light in medium 2 = v1/v2

Traits are inherited during a lifetime cannot be inherited in the successive generation as the changes do not reflect in the DNA of the germ cells. For example, a cricket player cannot pass on his skills on to his next generation as the traits acquired during his lifetime are limited only to non-reproductive cells. However, any mutations in the germ cells can result in the new traits being acquired by the successive generation.

Stomach mucus protects the gastrointestinal cells from the damage that gastric juices can cause. Gastric juices are highly acidic and, without this mucus, the acid can destroy the cells and tissues in the stomach.Mucus in the stomach is rich in bicarbonate, an alkaline compound, to help lubricate and protect the stomach. Stomach acid comes from the parietal cells, a type of stomach cell, and it is a hydrochloric acid, which is a solution of water and hydrogen chloride. This allows the environment in the stomach to be highly acidic. A high level of acidity is critical to inactivate bacteria in the food that people eat and to activate pepsinogen, a type of enzyme.

When CO2 is passed through lime water for a short duration, it turns lime water milky due to the formation of a white precipitate of calcium carbonate.

When CO2 is passed through lime water for a long time, then white precipitate of calcium carbonate which was formed initially dissolves due to the formation of soluble calcium hydrogen carbonate and solution becomes clear again.

When a ray of ordinary light is passed through a triangular glass prism, it splits to form a band of seven colours.
When light passes through a prism the light bends. As a result, the different colors that make up white light become separated. This happens because each color has a particular wavelength and each wavelength bends at a different angle.

- A precipitation reaction is a reaction in which an insoluble salt is formed. It is formed by the combination of two solutions that contain soluble salts.
- The insoluble salt that emerges out from the solution is termed to be precipitate.
- For example, the precipitate Silver Chloride is formed when Aqueous silver nitrate (AgNO3) is added to a solution containing potassium chloride (KCl).

Electric potential is the work done per unit charge in bringing the charge from infinity to that point against electrostatic force.
In a conductor, electrons flow only when there is a difference in electric pressure at its ends. This is also called potential difference.

Solenoid is coil having n number of turns of insulated copper wire. Magnetic field lines are produced around the solenoid when a current is passed through it. The magnetic field produced by it is similar to the magnetic field of a bar magnet. The field lines produced in a current-carrying solenoid is shown in the following figure.

When the north pole of a bar magnet is brought near to the end connected to the negative terminal of the battery, then the solenoid repels the bar magnet. It means the end of solenoid which is connected to the negative terminal of the battery behaves as north pole as like poles repel each other similarly the other and behaves as a south pole.
