1. If erythrocytes (RBCs) are incubated in the distilled water (pure water), what will happen to the cell volume of the RBC? Increases, decreases, or remains the same?

Increases

Explanation:

The RBC or Erythrocytes are permeable to water so the water flows inside and outside of the RBC. Usually, the concentration of solute in the cell is higher than the external environment therefore the water will move inside the cell.

When a cell is placed in the distilled water then the water will move from the higher potential to lower potential that is inside the cell and the cell will swell or the volume of the cell increases.

Thus, Increases is correct.

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.  

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.
