Jenna is helping her family decide which water filtration technology they should install in their house. Which of these provides the correct reasoning for method Jenna and her family should choose? A. reverse osmosis because it requires no filters, and removes all contaminants such as bacteria and chemicals
B. ultraviolet radiation because it requires no filters, and removes all contaminants such as bacteria and chemicals
C. ultraviolet radiation because it requires no energy, and removes all contaminants such as bacteria and chemicals
D. reverse osmosis because it requires low maintenance, and removes all contaminants such as bacteria and chemicals

List two limitations of natural selection

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.
