A study published in the late 1990s indicated a possible increase in endophthalmitis related to glaucoma surgery. The suspected cause of the infection was mitomycin C, an antifibrosis agent that prevents wound healing. Prevention of wound healing helps maintain drainage but also compromises barriers that normally prevent bacteria from entering the eye. A recent study was conducted to assess a new drug that prevents wound healing but which is also designed to reduce the incidence of postoperative endophthalmitis. The incidence of endophthalmitis in this study was found to be 12% in 25 patients given the new drug and 20% for 20 patients given mitomycin C. The difference in efficacy between the two drugs was not statistically significant. Which of the following may be concluded? (only one is correct) a. The new treatment is effective in reducing postoperative endophthalmitis
b. The new treatment is ineffective in reducing postoperative endophthalmitis

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).

Amale bird-of-paradise uses a dance to attract mates in which it flaps its tail feathers on the ground and jumps around a potential female mate. a different male bird-of-paradise does a similar dance but it jumps around the female in the opposite direction. the female bird is only attracted to one style of dance, in one direction.
