Text Solution

Verified by Experts

The correct Answer is:
B
Carotene is the source of retinal which is involved in formation of rhodopsin of rod cells. Retinal, a derivative of vitamin A, is the light-absorbing part of all visual photopigments.

In the first biological applicativon of bucky ball , chemists at the University of Califorminaat San F Francisoc and Santa Barbra made a discovery in 1993 that could help I designing drugs to rtreat AIDS . The human immunodeficienrcy virus (HIV) that causes AIES reproduces by syntheising a long protein chain , which is cut into smaller segments by an enzymecalled HiV-proteases . ONe way to stop AIDS , then might be to inacivate the enzyme. when the chemists reacted a water-soluble derivative of bucky ball with HIV-protease , they found that itbinds to the portion of th enzyme that would ordinarily clareve the repreouctive protein , preventing the HIV virus from reproducing . Consequently the virus could no bnolgre infect the human cells they had frown in the laboratory . The buycky ball compound itself is not a suitable drug for use against AIDS because of potential side effects and delivery difficaultes , but it does provide a model for the development of such drugs Consider following statements about bucky ball : A , It is also called fullerene B: It is also called Buckministerfullerene C: Bucky tubes (made of fullerenes ) are several times stronger than stel whnires D: Bucky ball is a plastic polymer Select correct statement (s) :

A list of steps involved in mechanism of vision is given below in a random order. (i)Neural impulses are analysed and image formed on retina is recognised by visual cortex. (ii)Membrane permeability changes (iii)Ganglion cells are excited (iv)Bipolar cells are depolarised (v)Action potentials (impulse) are transmitted by optic nerves to visual cortex. (vi)Potential differences are generated in the photoreceptor cells. (vii)Light energy causes a change in shape of rhodopsin, leading to the dissociation of retina (an aldehyde of vitamin A ) from opsin (a protein) (viii)Structure of opsin is changed. Which of the following options represents these events in a correct order ?

Consider the following four statemets (A - D) related to organic farming and select the correct option stating which ones are true (T) and which ones are false (F).
