Answer:
The answer is: a. Climacteric
Explanation:
Climacteric is the time in the midlife of a woman that starts with the diminution in ovarian activity (less production of estrogen and progesterone) until the end of ovarian function. It is the compilation of gradual changes of ovarian function that happen before the menopause (cessation of menses) and continue for a while.
The phases of the climacteric are pre-menopause, menopause and post-menopause. During the pre-menopause, hormonal changes will take place, there is a decrease in estrogen and progesterone production.
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.
