The majority of humans use one hand more often for tasks, especially tasks that require fine motor skills. joyce believes that cats have a dominant paw. she tests ten cats in two experiments. for the first experiment, she places a small piece of tuna on each cat’s head. she then observes which paw the cat uses to wipe it off. during the second experiment, she dangles a toy above the cat’s head. she observes and records which paw each cat uses to bat at the toy. she then compares the results from the two experiments. what is the hypothesis in joyce’s experiment? a) the majority of humans have a dominant hand. b) cats favor the use of one paw over the other. c) test subjects were kept constant throughout experimentation. d) two experiments were performed to test which paw cats preferred.

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).
