Answer:
By breathing when oxygen enters the body it goes to alveoli and gas exchange occurs then carbon dioxide comes out of the the body
Answer:It would maintain high cAMP levels and elevate glucose mobilization.
Explanation:
Gas stimulates adenylate cyclase, leading to the generation
of cAMP. This signal then leads to glucose mobilization. If cAMP phosphodiesterase were inhibited, then
cAMP levels would remain high even after the termination of the
epinephrine signal, and glucose mobilization would continue
A)When body temperature increases, sweat is produced as a cooling agent to lower body temperature.
Negative feedback loop is a state where an event is monitored and regulated to have an optimal level. For instance, in this given example, when body temperature increases over 37C, to normalize the body temperature sweat is produced by the skin.
