Select each correct answer. more than one answer may be correct.
the components of the human body, from organ systems to cell organelles, interact to maintain a balanced internal environment. to successfully accomplish this task, organisms possess many different receptors that detect deviations in the body's internal state and initiate corrective actions.

in which of the following ways does the body respond to an increase in skeletal muscle cell activity?

a. by converting white bloods cells to red blood cells
b. by increasing the heart rate
c. by increasing the respiratory rate
d. by producing less hemoglobin

b. by increasing the heart rate

c. by increasing the respiratory rate

Explanation:

Increased activity of skeletal muscles would require an increased supply of oxygen to these cells to sustain the muscle contraction. Muscle cells perform aerobic cellular respiration in the presence of oxygen and produce ATP molecules to be used during muscle contraction. Therefore, there is an increase in heart rate to pump sufficient blood to the skeletal muscles which in turn ensures enough supply of oxygen. Also, there will be an increase in the respiration rate to inhale the required oxygen.

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.
