PLEASE HELP ONLY IF YOU KNOW! THANKS! Two ecosystems are compared in terms of population size and species diversity. One ecosystem has a large number of individuals but low species diversity, while the other ecosystem has fewer individuals but greater species diversity due to high mutation rates. Which of the following statements best describes how these two ecosystems would respond to an environmental stress such as drought?

a) The ecosystem with greater diversity is less dependent upon resources and would suffer less from the drought.
b) The ecosystem with greater diversity is more stable and would, therefore, be more likely to withstand the drought.
c) The ecosystem with more individuals is less likely to suffer because it is more productive and, therefore, more stable.
d) The ecosystem with more individuals is more likely to have members that are drought-resistant and will survive and reproduce.

Astudent drew the following flowchart to show the movement of nutrients. soil → roots → plants →? where does nitrogen go next? a. directly into nearby animals as nutrition b. directly into aquifers through condensation c. directly into the air through evaporation d. directly into nearby plants during fixation

What happens when the cell copies its chromosomes

Considering the yellow and green pea color phenotypes studied by gregor mendel: a. what is the biochemical function of the protein that is specified by the gene responsible for the pea color phenotype? (1 point) b. a null allele of a gene is an allele that does not specify (or encode) any of the biochemical function that the gene normally provides (in other words, either no protein at all or only non-functional protein is produced from it). of the two alleles, y and y, which is more likely to be a null allele? (1 point) c. in terms of the underlying biochemistry, why is the y allele dominant to the y allele? (2 points) d. why are peas that are yy homozygotes green? (1 point) e. the amount of protein produced from a gene is roughly proportional to the number of functional copies of the gene carried by a cell or individual. what do the phenotypes of yy homozygotes, yy heterozygotes, and yy homozygotes tell us about the amount of sgr enzyme needed to produce a yellow color? explain your reasoning.
