In mammals milk is digested by action of:
- Rennin
- Amylase
- Intestinal bacteria
- Invertase
The Correct Option is A
Solution and Explanation
In mammals, milk is primarily digested by the action of rennin and other enzymes. Rennin is responsible for curdling milk in the stomach, which aids in the digestion of milk proteins. Other enzymes, such as lactase, help break down lactose, the sugar found in milk. Intestinal bacteria can also play a role in further digesting milk components.
So, the correct option is (A): Rennin

- Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : The potential (V) at any axial point, at 2 m distance(r) from the centre of the dipole of dipole moment vector \(\vec{P}\) of magnitude, 4 × 10-6 C m, is ± 9 × 103 V.
(Take \(\frac{1}{4\pi\epsilon_0}=9\times10^9\) SI units)
Reason R : \(V=±\frac{2P}{4\pi \epsilon_0r^2}\), where r is the distance of any axial point, situated at 2 m from the centre of the dipole.

Digestion and Absorption - Alimentary Canal
Digestion can be defined as the process of breakdown of large, insoluble and complex food molecules into smaller ones for its absorption and circulation in the body. This process involves the usage of a variety of digestive fluids and enzymes, including saliva, mucus, bile and hydrochloric acid, among others.

The alimentary canal is mainly referred to as the pathway by which food enters our body and moves out through the anus after digestion. It is a tube-like structure that starts from the mouth and ends in the anus. The alimentary canal plays a primary role in human digestion and is also termed as the digestive tract.
Peristalsis is a series of wave-like muscle contractions that move food through the digestive tract.
