Explanation:
The process that is directly responsible for the formation of the bud on the hydra is;
B - Mitosis
<span>Sympathetic dominance---
Increase in muscle mass----- Raise
Decreased in insulin----- </span>Lower the tmr<span>
Decrease in TSH ---- Lower the tmr
Increase in adrenal cortex function ------</span>raising the tmr<span>
Increase in thyroxine ---- </span>raising the tmr<span>
Training for a marathon -----raising the tmr
Malabsorption of nutrients-------- </span>Lower the tmr<span>
Decrease in adrenal medulla function ------ </span>Lower the tmr<span>
Epinephrine secretion------- </span>raising the tmr
The total metabolic rate is the total energy used by the body each day. Physical activity such as Training for a marathon require more energy and leads to increasing the tmr. Whereas, malabsorption of nutrients lowering the tmr because less food is being supplied, and therefore less energy production.
