Phillip was performing a laboratory exercise on how temperature affects a plant's cellular activity. he discovered that when exposed to high temperatures (around 50 degrees celsius), the overall rate of glucose production by photosynthesis decreased. which of these conclusions would best explain why this occurred? a) the high temperatures denature the proteins in the plasma membrane, thus making many of the cells unable to function properly. b) the higher temperatures hardened the plasma membrane not allowing glucose to leave the cell. c) the temperature decreased the availability of oxygen to the plant. d) as you increase the temperature, the plant cells go dormant. elimi

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?
