State the alternative hypothesis for the experiments shown in Figure 3. The scientists claim that, in the absence of AMP, PFK of red king crabs functions efficiently at the crabs' typical low environmental temperatures because the active site of the enzyme can bind substrate more tightly at the low temperatures than it does at higher temperatures. Support the scientists' claim based on the data provided. Predict the effect on the rate of the reaction catalyzed by PFK in the experiment shown in Figure 2 if increasing concentrations of FBP are added to the reaction.

What adaptations can prey use to avoid predation

Humans are believed to have evolved in coastal regions in east africa. the region had an abundant supply of fish for early humanoids to eat. when scientists analyze the fads gene they see an interesting pattern. people whose families have lived in this area of east africa for generation show a high level of diversity in alleles for the fads gene. conversely, people whose families had migrated inland a moderate distance from sources of fish showed a much lower diversity for fads gene alleles. additionally, the fads alleles found in people whose family has lived inland for generation are almost all gene alleles which produce fads proteins with a high level of function and activity. how do anthropologists explain this?
