Questions Asked in NEET exam
- 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.

Animal Tissues
Human bodies, like most animal bodies, are made up of four different types of tissue:
Epithelial Tissue:
This tissue forms the outer layer of the body and also lines many of the body's cavities where it has a protective function.
General functions of epithelial tissue:-
- Provides a barrier between the external environment and the organ that it is covering.
- Specialized to function in secretion and absorption.
- Protects organisms from microorganisms, injury, and fluid loss.
Connective Tissue:
This tissue assists in the support and protection of organs and limbs and depending on the location in the body it may join or separate organs or parts of the body.
Muscle Tissue:
This tissue enables various forms of movement, both voluntary and involuntary.
Nerve Tissue:
This tissue is responsible for the carrying of electrical and chemical signals and impulses from the brain and central nervous system to the periphery, and vice versa.
