The graph shows how the population of mice changed over a four-year period. Suppose that mice are the main food for owls. Based on the graph, during which year would the number of mice have been most limiting to the owl population?

genetic variation will increase because of a new habitat and food source.

explanation:

idk im sorry.

these muscles maintain the blood pressure in the vessels. the smooth muscles are innervated by nerves of the autonomic nervous system. when the muscles contract, they cause vasoconstriction of the vessels and increase blood pressure. when the muscles relax, they enable vasodilation of the   blood vessels hence reduce blood pressure.
