Which statement about the specific immune response is false?
a. each t or b cell has antigen receptors for only one specific antigen.
b. t and b cells recognize antigens by using antibodies bound to their surface membranes.
c. unique antigen receptors are created by genetic recombination.
d. antigens must be presented by an mhc molecule for t and b cells to recognize them.
e. all cells express mhc-i molecules, but only antigen-presenting cells express mhc-ii molecules.

when a reversible reaction is occurring in both directions at the same rate; the products and reactants do not change in concentration. a chemical reaction where the compound is broken into its constituent parts.

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.
