Answer:
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.

A single gene disorder is one that's known to be caused by a single gene. Multiple gene disorders, however, can be caused by multiple gene combinations and other factors. Dominant genes are always expressed in the offspring, while recessive genes are only expressed if the offspring recieves the recessive gene from both parents. Sex-linked genetic disorders occur most often in men, and are caused by a single-gene disorder gene being on the X chromosome but not the Y, so that the offspring needs only one recessive gene to have the trait/disorder.
Does this help? Any more questions?
Both dolphins and whales still have their hip (pelvic) bones present. These bones connect and transfer the weight of the trunk to the lower limbs.
Thus, <em>the presence of the pelvic bone may indicate that whales had ancestors that walked on land</em>.
