What determines if a bacterial cell is gram-positive or gram-negative? 2. in this lab, both viruses and prions were introduced as acellular organisms. do some research and describe one other type of acellular organism. what characteristics about this organism classify it as acellular? 3. bacteria have many different shapes that often determine their class. research and form a hypothesis on the evolutionary reasons for so many different bacterial morphologies, 4. do a search online or look in your textbook for 1-2 antibiotics that affect gram-positive bacteria and list them. on what part of the cell do the antibiotics usually work? list one or two antibiotics that affect gram-negative bacteria? on what part of the cell do the antibiotics usually work? (be sure to cite your sources in your answer.) 5. why do you think it is important to identify a bacterial disease in a patient before prescribing any antibiotic treatments? (be specific.)

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.
