What characteristic makes osmosis different from diffusion?

a: osmosis occurs through a semipermeable membrane. diffusion occurs through a permeable membrane.

b: net movement in osmosis is from areas of higher concentration to areas of lower concentration. net movement in diffusion occurs from areas of higher concentration to areas of lower concentration.

c: osmosis requires facilitation by an energy-carrying molecule, such as atp. diffusion requires no additional energy to move molecules across the concentration gradient.

d: osmosis is used for gases, such as oxygen and carbon dioxide. diffusion is used for water that contains salt or sugar molecules.

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.
