Before placing the potato in the beaker, the student used an electronic balance to determine the mass of the
potato cube. the mass of the cube was determined again after it was in the beaker for an hour. describe how
this information could specifically be used to determine if water moved during the investigation. [1]

The mass of the cube would increase if the water moved into the potato cube or the mass of the potato cube would decrease if the water moved out of the potato cube after placing it in the beaker.

Osmosis can be described as a process by which water moves from an area of higher concentration to an area of lower concentration along the concentration gradient. It is a type of passive transport.

If the potato cube is placed in water, most likely the water will enter into the cell as the concentration of solutes will be more in the potato cube and the concentration of water will be less. Hence, the mass of the potato cube would increase.

answer: c. two haploid cells

explanation:

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.
