Explanation:
Growth hormone (gh) hypersecretion causes gigantism when it begins in childhood, but it is more likely to cause acromegaly when it begins in adulthood.
Growth hormone also called somatotrophin is a type of peptide hormone that helps in growth, cell reproduction, and regeneration.
Growth hormone hypersecretion during childhood can result in gigantism or abnormal growth most notable in terms of height.
When its secretion is higher in adult stage it can cause a condition called acromegaly in which here is excessive growth of cell causing enlargement of hands and feet, enlargement of facial features along with other difficulties like enlarged organs, fatigue, erectile dysfunction, etc.

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.
