Vitamin - E

Hide Solution

Verified By Collegedunia

The Correct Option is C

Solution and Explanation

Vitamin K is necessary for the synthesis of prothrombin in the liver. Prothrombin is a factor which is required for blood clotting. Deficiency of vitamin K leads to slow rate of blood clotting. Vitamin A deficiency leads to night blindness, xerophthalmia and retarded growth. Vitamin B deficiency causes beri-beri, pellagra, anaemia etc. Deficiency of vitamin E leads to destruction of RBCs.

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.
In the light of the above statements, choose the correct answer from the options given below :

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.
