a.

b.

c.

d.
the matter is converted to energy only.

Answer to this question is option C i.e. The matter is converted to energy and carbon molecules.

Explanation:

All the living beings from plants to animals are made up of carbon, and so is carrot, being a part of a plant. When an animal, say rabbit, consume this carrot, they receive the carbon from the carrot in the form of carbohydrates and proteins. This carbon combines with the oxygen in the animal cell to produce energy and also releases residual carbon in the form of carbon dioxide. Hence, after consumption of carrot by the rabbit, the matter in the carrot is converted to energy and carbon molecules.

what statement best describes the difference between the sympathetic and parasympathetic nervous systems?

the sympathetic nervous system prepares the body for intense physical activity and is often referred to as the fight-or-flight response. the parasympathetic nervous system has almost the exact opposite effect and relaxes the body and inhibits or slows many high energy functions.

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.
