During a bacterial infection, macrophages will seek out and engulf the invading bacteria into vesicles via phagocytosis. The bacteria will then be degraded inside the macrophage. Which organelle do you think participates directly in this degradation process

After the microorganism is ingested by the white blood cell a vesicle that contains the pathogen is formed. This vesicle fuses with an organelle that contains up to 40 hydrolytic enzymes. That organel is called a lysosome

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.  

not only is it colder, it also becomes darker, less salty, and more dense.
