The horizontal axis of the cladogram depicted is a timeline that extends from 100,000 years ago to the present; the vertical axis represents nothing in particular. the labeled branch points on the tree (v–z) represent various common ancestors. let’s say that only since 50,000 years ago has there been enough variation between the lineages depicted here to separate them into distinct species, and only the tips of the lineages on this tree represent distinct species. in darwin's tree of life, each fork in the tree represents
a) groups of extinct organisms.
b) the most recent common ancestor of the subsequent branches.
c) morphologic gaps in the fossil record.
d) groups of living organisms.

The answer is B. The most recent common ancestor.

Explanation:

Cladograms are used to illustrate relationships related to morphological and evolutive traits. So then,  in a cladogram when organisms are closely related, they appear closer in the branches. Common branches and nodes mean close relationships and common ancestors on a scale of time.

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.
