The process of keeping the internal environment of the body stable by responding to changes in the external environment is known as homeostasis. Which of the following accurately describes a
mechanism for maintaining homeostasis at the cellular level?
A. Passive transport, where ATP is used to facilitate the movement of molecules from high to low
concentrations.
B. Facilitated transport, where enzymes are used to increase the rate of solvent transfer across a
membrane.
C. Active transport, where the solution is pumped across a membrane to from high to low
concentrations.
D. Active transport, where molecules are pumped across the cell membrane against the gradient
from low to high concentration.

Scenario 5 1) take 10 red and 10 black beans and place them, mixed, on the table. record the starting phenotype # and frequencies (% of your total population) of your starting population in the table provided (generation 0). 2) act as a predator. “capture” as many organisms as you can until you have reduced the population to three organisms. put them aside. at this point, the predators die. 3) the remaining organisms each produce 2 clonal offspring. multiply your organisms accordingly and allow them to mix on the table. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 1). 4) repeat the reproduction event, allowing each of your organisms to produce 2 clonal offspring. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 2). 5) repeat the reproduction event, allowing each of your organisms to produce 2 clonal offspring. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 3).
