The answer is sensory neuron. There are three types of neurons & their
functions
Sensory neurons - carry impulses from
the sense organs to the spinal cord & brain
Inter neurons - connect sensory and
motor neurons and carry impulses between them
Motor neurons - carry impulses from
the brain and spinal cord to muscles & glands.

You didn't put the answer options, but the frog life cycle phases are:
- Mating: In this phase two adult frogs, a male and a female, mate in the water or on plates. At this point, the male frog wraps his arms around the female and overlaps over her back.
- Spawning: At this point, the female releases the eggs into the water, ready to be fertilized by the males. Fertilization occurs outside the female's body.
- Eggs: Some fertilized eggs will be devoured by small animals, but those that survive will hatch 7-9 days after fertilization, releasing a frog shape, called a tadpole.
- Tadpole: It is similar to a fish and is formed by tail, mouth and gills. After 7 days of life, you will be able to swim and feed on algae. Four weeks later he will develop teeth and skin. When he reaches 9 weeks he will begin to change his shape, growing in size and developing head and legs. At that moment it will look more like a frog, but it still has a long tail.
- Metamorphosis of the fish: Up to twelve weeks of age it will reach the shape of a frog and start to feed on insects. Gradually it will lose its tail and its tongue will grow. The 16 weeks will become an adult frog, being able to mate and restart the cycle.
The best answer is c. Removing calcium from its own bones would be counter productive, and many animals don't possess the ability to make calcium from other elements, or removing calcium from the air.
Hope this helps!
