[gt.03]a scientist studied the limb structures of three organisms and made their models as shown below.
picture shows the limb of three organisms with similar limb bone structures. all three organisms share common characteristics, most particular in the bones and joints. the first figure has a hand, the second figure has a claw with talons, and the third figure has a hoof; they all have parts that must bend agreeably in order to function properly.
which of these conclusions is most likely correct about the organisms studied by the scientist?
they hunt in a similar way.
they have similar habitats.
they evolved around the same time.
they evolved from the same ancestor.

D. They evolved from the same ancestor.

Explanation:

In the event that at least two species share a one of a kind physical characteristic they may all have acquired this quality from a typical predecessor.

Attributes that are shared because of basic family are homologous structures. For instance, the forelimbs of whales, people, and birds appear to be unique outwardly on the grounds that they're adjusted to work in various conditions.

Nonetheless, on the off chance that you take a gander at the bone structure of the forelimbs, the association of the bones is comparative crosswise over species.

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.
