is sometimes called autoregulation

The strength of a muscle contraction is influenced by the :

All of the above- amount of load, initial length of muscle fibers, and recruitment of motor units

During inspiration, the expansion of the lungs causes:

a decrease in alveolar pressure

Which of the following would you expect to happen to cellular respiration during exercise?

Increased cellular respiration occurs during exercise, causing a rise in plasma PCO2, which is detected by central chemoreceptors in the brain and perhaps peripheral chemoreceptors in the carotid sinus and aorta to cause an increase in respiration rate.

Hydrolysis refers to:

using water to split larger compounds into smaller ones

A decrease in blood pH below normal tends to:

stimulate increased respirations.

The main advantage of sexual reproduction over asexual reproduction is:

there is greater diversity in the offspring.
