Explanation / Answer

96) Cardiac muscles contain more mitochondria than skeletal muscle. But, at the same time it depends on continuous supply of oxygen. So, the given statement is false.

97) The factor that can be quickly adjusted to regulate blood flow is peripheral resistance. This can be done by changing the diameter of peripheral blood vessels.
