The eyes of cat, cow, buffalo and some n...

The eyes of cat, cow, buffalo and some nocturnal animals shine in night. It is due to presence of tapetum lucidum between the chorid and retina. This shining is due to the presence of a pigment made of

A

Cytokine

B

Uracil

C

Guanine

D

Thiamine

Text Solution

Verified by Experts

The correct Answer is:
C
Among many nocturnal vertebrates the white compound guanine is found in the epithelium or retina of the eye. This provides a mirror like surface, the tapetum lucidium which reflect outward and thereby allow a second chance for its absorption by visual pigment at very low intensities.

An irregular shaped non conductor has some charge distribution. The potential difference between the two points A and B in it is V. If it is now enveloped in an spherical non conducting shell having uniform charge distribution in it, the new potential difference between the points (neglect any induction due to presence of charge)

An atom is assumed to tbe spherical in shape and thus, the size of atom is generally given in terms of radius of the sphere and is called atomic radius. It is usually defined as the distance between the centre of the nucleus and outermost shell where electron are present. The exact measure of atomic radius is not easy due to following reasons: (i) The atom does not have well defined boundary. the probability of finding the electron is never zero even at large distance from the nucleus. (ii) It is not possible to get an isolated atom. the electron density around an atom is affected by the presence of neighbouring atoms, i.e., the size of the atom changes in going from one set of environement to another. (iii) the size of an atom is very small, of the order of about 1.2 Å,i.e., 1.2xx10^(-10)m . An estimate of the size of the atom can, however, be made by knowing the distance betweent he atoms in the combined state. the distance between the atoms, i.e., bond length are generally measured by the application of techniques such as X-ray differaction, electron diffraction, infrared spectroscopy, nuclear magnetic resonance spectroscopy, etc. However, bond lengths change with different type of bonding.

An atom is assumed to be spherical in shape and thus, the size of atom is generally in term of radius of the sphere and is called atomic radius.

The propability of finding the electron is never zero even at large distance from the nucleus. (b) It is not distances from to get an isolated atom.
