you think? write a hypothesis. then, describe at least two ways you would investigate the
hypothesis.

no, because if they were the same species wouldn't they look the same . my hypothesis is that they are different species but in the same family

Explanation:

this protocol provides a detailed procedure for chromatin immunoprecipitation (chip) to study the dna-protein interactions.

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.
