The students observed that the test tube water from the grated potato beaker was a dark blue-black color, while the chunked potato water was medium blue. What would be an appropriate hypothesis for the experiment?

A) Mechanical digestion always precedes chemical digestion.
B) If food is chewed first, then mechanical digestion will take place at a much faster rate.
C) The greater the surface area of the food exposed, the faster the rate of chemical digestion.
D) If enzyme action is represented by the iodine color change, then chemical digestion will not take place without mechanical digestion.

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.  

i think the answer would be a. after sentence 14! i hope i at least a little
