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.

The heat of fusion of the ice is the amount of energy that is required in order to melt one gram of ice. In this item, in order to solve for the heat of fusion, we simply have to divide the given energy by the mass. 
                     heat of fusion = 16650 J / 50 g = 333 J/g
Thus, the heat of fusion of the ice is 333 J/g.

Oxygen is an abiotic factor that is beneficial by-product of primary production.
<u>Explanation:</u>
The non living parts of an ecosystem that mainly affects the living organisms in it are called as an abiotic factor. These can include soil, temperature, water, oxygen and sunlight. The major energy source in earth is Oxygen which is abiotic factor. 
It is very essential for the photosynthesis process to take place. Here, the plants converts water and carbon dioxide into oxygen and sugar. This becomes food for plants. Then these plants are eaten by animals. Thus oxygen is an important and beneficial by-product of photosynthesis. Oxygen is also very important for the survival of human beings.
