Answer:
A. Blood would leak backwards through the damaged valves due to gravity, causing lower leg swelling.
Explanation:
The passage of blood is always in a single direction in the vein due to the presence of valves in the veins.
Any kind of vein injury or vein rupture, causes the valves in the veins to not function in an appropriate manner. The injury might result in inappropriate opening and closing of these valves. The inappropriate functioning of the valves causes the blood to flow backwards. This will eventually lead to blood pooling and putting more pressure on the lower leg veins. hence, there would be swelling in the lower legs.
Habitat
Explanation:
Habitat is a given area where organisms interact with non-living things.
The dwelling place of living organisms is their habitat and it is the produced as a result of interaction between the organism and non-living components.
- The habitat of an organism defines its niche in such an environment.
- This is related to the roles which organisms perform in the ecosystem.

Although its research is still substantial, it is still considered as a matter of ethical issue.
