The birds in the model above share the same common ancestor. A drought has killed most of the insects in their environment. What is a possible result from this change in the environment? A. The population of the seed eating birds will not be affected because their food source is not changing.

B. The population of insect eating birds will adapt so they can eat seed to avoid starvation.

C. The population of woodpeckers will change their beaks to be able to eat the seeds to avoid starvation.

D. The population of seed eating birds will go extinct because they will not have a food source.

Which properties describe all matter?

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).
