regulation of the diameter of blood vessels and control of blood pressure

Explanation:

Skeletal muscles are the multinucleated muscles with striations and are attached to the bones (skeleton). The main function of skeletal muscles is to generate the voluntary movement of the body or body parts. The skeletal muscles of face, rectum, and urinary bladder generate their voluntary movement as per the will of the organism. On the other hand, blood vessels are lined with smooth muscles with spindle-shaped cells.

For example, the muscles present in the subcutaneous layer of the skin of the face are responsible for various facial expressions. Contraction of these facial muscles brings about the movement of skin of the face to generate a wide variety of emotions. Smooth muscles of blood vessels are involuntary in nature.

Vasodilation and vasoconstriction as brought about by smooth muscles of blood vessels are regulated by the autonomic nervous system. Under the conditions of lower blood pressure, contraction of smooth muscles of blood vessels restore the reduced blood pressure. On the other hand, when the blood pressure rises above the normal range, the smooth muscles of blood vessels relax to dilate them and to lower down the blood pressure.

c. Harvesting practices that do not reduce the potential for future harvests.

The aquatic environment is the home of several species of fish and invertebrates which are commonly consumed by the human population. The fishing is done on large commercial scale to meet the food requirements of the increasing human populations. The sustainable fishing is a practice which aims to secure the edible aquatic organisms so that they remain available to meet the food requirements of the future human population, also aims that no aquatic species should be decreased to a number which can lead to it's extinction.  

According to the above information, Harvesting practices that do not reduce the potential for future harvests is the statement which defines sustainable fishing practices.
