What type of membrane junction would you expect to be most plentiful in the bladder? why?

The correct answer is tight junctions.  

Tight junctions comprise weblike strands of transmembrane proteins, which combines with the outer surfaces of adjoining plasma membranes together to lock the passageways between the adjacent cells.  

The cells of epithelial tissues, which lines the urinary bladder comprise many tight junctions to reduce the passage of components amid the cells and inhibit the constituents of these organs from seeping into the surrounding tissues and blood.  

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.
