Answer:
D. Receptors in the eye respond to a different type of input than receptors in the skin.
Explanation:
The sensory receptors in the eye have a different structure than the sensory receptors in the skin because the sensory receptors in the eye respond to a different type of input than receptors in the skin. There is always a relation between structure and function. The structure is modified in such a way that it can perform a particular function. For example, the eye is made to receive the light signal while receptors in the skin are made to receive signals such as touch, heat, cold, etc. Thus the sensory receptors have a different structure according to the signal they receive.
But why are the other answers wrong?
A. There is no relation between the number of receptors and the function of receptors in different organs of our body.
B. All the sensory receptors send signals to the brain.
C. All the sensory receptors are connected with nerve cells.

Option (2).
Explanation:
Zygote is formed by the fusion of the male and female gamete during the process of sexual reproduction. The zygote undergoes further development inside the female womb.
