What is allosteric regulation? a) in allosteric regulation, genes are expressed constitutively. b) in allosteric regulation, a small molecule binds to a large protein and causes it to change its shape and activity. c) in allosteric regulation, a gene is turned off by a repressor protein. d) in allosteric regulation, a gene is turned on by an activator protein

b) In allosteric regulation, a small molecule binds to a large protein and causes it to change its shape and activity.

Explanation:

Allosteric regulation refers to the activity control of an enzyme by binding small molecules to regulatory sites on It. This binding causes an alteration of the protein conformation and consequently the shape of the active site and its catalytic activity are altered. Regulatory enzymes can act by either stimulating or inhibiting the activity of a protein.

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.
