An example of natural selection is the tail of a male peacock. the females of the species choose mates based on the colors of the males’ tail feathers. if females begin using different criteria than feather color when they choose mates, what would most likely happen to the tails of peacocks over time?

a. increased variation in tail feather color because the selection pressure has been relieved
b. increased variation in tail feather color because the peacocks try different ways to impress the females
c. decreased variation in tail feather color because no form of the trait is advantageous
d. decreased variation in tail feather color because the only reason for variation was selection pressure

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).

Beth’s hygrometer is reading a temperature of 30 c and a relative humidity of 65%. the humidity in the air is?

2. sketch the inside of the bean nodule, and describe or label what you observed with the hand lens.
