C. The problem of endangered species
That's a hard one but I would go with A unwanted transpitation. Hope that helped :)
Answer:

Explanation:
Cerebellum is a leaf-like structure that is a part of the hind brain and is responsible for:
- coordinating skeletal muscle movements.
- controls movements, posture and balance.
- involved in learning too.
So, if the cerebellum of the brain is affected/injured, a person can have difficulty in keeping their body in a balanced position, coordinate voluntary movements of skeletal muscles and learning.

Answer:
Explanation:
The complete question is as follows :
Animals that maintain internal body temperature using heat generated by their own metabolism are called:
A)thermoregulators.
B)hibernators.
C)aerophiles.
D)endotherms.
E)dormants.
- An animal that is capable of maintaining a body temperature that is metabolically favorable for the organism is known as an endotherm.
- The body temperature is maintained by an endotherm by using its internal body capacity to generate heat rather than depending on the ambient temperature.
- Some of the mechanisms used by endotherms to maintain a suitable internal body temperature include shivering, uncouple oxidative phosphorylation, sweating, flushing, etc.
- The endotherms include birds and mammals.
- The ability to perform endothermy is owed to the presence of a large number of mitochondria that enables the organism to increase the rate of metabolism to generate heat as and when required.
Metabolism involves the over-all chemical reactions of the body. It is divided into two kinds. The first one is catabolism which is the breaking down of molecules to acquire energy. Anabolism, the other type, is the synthesis of all the molecules that are needed by the cells.
