Puerto Rico, Cuba, Jamaica, and Hispaniola have species of anole lizards with distinct body types, including the grass lizards, which have long tails; the canopy lizards, which have large toe pads; and the twig lizards, which have short legs. Anole species with each of these three body types exist on each of the:

four islands.

Explanation:

Anole lizards includes different types of lizards such as the canopy lizards, the grass lizards and the twig lizards and are found in Puerto Rico, Cuba, Jamaica, and Hispaniola.

Anole species with each of these three body types exist on each of the four islands because of interisland migration  events.

The anole species share common ancestor with each other in comparison to other lizard species, interisland migration  events allowed anole species  to get evolved by natural selection process in different islands including Puerto Rico, Cuba, Jamaica, and Hispaniola.

Hence, the correct answer is four islands.

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.
