Answer:
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.
Answer:
If there is an increase in the shark population, then there will be a slight decrease in the other populations.
Explanation:
Based upon the three animals listed, the shark is at the top of the food chain. This means that the shark will eat the sea otter and see star, declaring their population will decrease.
If the disease was cause by the dominant allele, every person with said gene would be affected with the disease. if the genetic allele is recessive, both parents can be carriers (hetero) without being affected. that makes it easier for the genes to keep being passed on.
hope this helps!
<span>This kind of relationship is called mutualism and is defined by both parties being equally beneficial to each others survival. An example of this kind of relationship is found a lot in nature, as with the relationship between fish and coral reefs in the sea. Corals provide shelter and protection for the small fish while the fish in return also provide protection from algae and seaweed invading in on their space and killing off the coral.</span>
1. The cells divide by constriction of a protein, it is true in case of Bacteria and Animals, and false in case of Plants.
2. The presence of a cell wall inhibits the cell from differentiating by constriction, it is false in case of bacteria; though bacteria exhibit a cell wall but still divide by constriction. It is also false in case of animals, but true in case of plants.
3. Tubulin-like molecules or tubulin subunits function in the division of the cell. The statement in true in case of bacteria and plants, but is false in case of animals.
