The diagram shows a model of the evolution of the eukaryotic cell. According to this model, how did eukaryotic cellular organelles evolve?

Mitochondria developed from endosymbionts, and then some mitochondria evolved into chloroplasts.

Both mitochondria and chloroplasts developed from endosymbionts at the same time.

Chloroplasts developed from endosymbionts, and then mitochondria developed from other endosymbionts.

Mitochondria developed from endosymbionts, and then chloroplasts developed from other endosymbionts.

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.
