Your question was.... "What layer of the blood vessel wall is composed of areolar connective tissue containing elastic and collagen fibers"
Your answer is the Tunica intima, Because, The blood vessel's tough outer layer is made up of connective tissue, which permits it to withstand stresses occurring on the vessel wall. It also contains strong collagen fibers that help bind the blood vessel to surrounding tissues, providing stability to the vessel.
I really hope this helps! :)

As the population density increases therefore we probably have an increase in birth rate, aslo less space becomes available to individuals and if competition increases that means we probably have an increase in fighting (contest competition) therefore there might be an increase in individuals dying. Therefore I would say the answer is (c) the increase in population density would cancel out the competition. Hope this helps :).
