  1. Good vision depends on adequate intake of carotene rich food. Select the best option from the following statements:
    (i) Vitamin A derivatives are formed from carotene
    (ii) The photopigments are embedded in the membrane discs of the inner segment
    (iii) Retinal is a derivative of Vitamin A
    (iv) Retinal is a light absorbing part of all the visual photopigments
    Options:

    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. Photopigments are occur entirely on the surface of membrane disc.

    Sympathetic system prepares the body for stress or emergency conditions while parasympathetic system is associated with the period of rest. So when one faces the stress or emergency conditions sympathetic system enlarges the pupil to allow more light in the eye while during rest, parasympathetic nervous system constricts the pupil to its normal condition.

    Afferent nerve fibres – sensory nerve fibres which carry senses from receptors to brain or spinal cord (CNS). Efferent nerve fibres – motor nerve fibres carry orders or responses from CNS to effectors (muscles and glands).
