Hemoglobin is a quaternary protein structure on a red blood cell involved in oxygen transport. Hemoglobin A1 has two a-chains and two ß-chains. Hemoglobin A2 has two a-chains and two o chains. In spite of the structural
differences, both hemoglobin A1 and A2 perform the same functions.
Which of the following statements explains why both hemoglobin types perform the same functions?
O The amino acid sequence in the delta chain is not critical to oxygen transportation.
O Only the alpha chains are important for oxygen transport
O The delta chains are nonfunctional and the body compensates with more red blood cells.
O The amino acid sequences changed the alpha and beta chains because of molecular interaction.

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).
