Reforestation is a biodiversity method that can increase the biodiversity by replanting with trees. Reforestation will help forest recuperate from logging, rest fires and human abuse. Replanting trees will increase the density and variety of the trees and by doing so, wildlife will also increase. Although reforestation is a common approach to relive forest, forest management is still needed to maintain the endemic or native species.
Answer:
B) Regurgitation
Explanation:
Regurgitation refers to the backward flow of blood due to any reasons. Presence of atrioventricular valves between atrium and ventricle prevents the regurgitation, that is backward flow of blood. Structural or functional damage of any atrioventricular valves does not allow them to prevent the regurgitation.
Example: Valvular insufficiency is the condition wherein the cusps of the valves (mostly the mitral valve) become stiff and leads to backward flow of blood.
