Which statement best describes photophosphorylation? it is the conversion of light energy to chemical energy. it is the flow of hydrogen ions down a concentration gradient. it is the process by which light energy is captured to form simple sugars using water and carbon dioxide and to release oxygen gas as a byproduct. it is the addition of a phosphate group to adp to form atp using light energy absorbed during photosynthesis.

Suppose a particular species of tulip plant has three alleles for the gene that codes for flower color. the cr allele produces red tulips, the cp allele produces purple tulips, and the cw allele produces white tulips. cr is dominant over cp and cw, and cp is dominant over cw. for each of the following crosses, determine the expected ratio of offspring for each flower color. cr cp x cp cw cr cw x cp cw 1 red: 1 purple : 0 white, 1 red: 2 purple: 1 white, 2 red: 1 purple 1 white, 1 red: 3 purple : 0 white, 2 red: 0 purple : 2 white, 2 red: 2 purple : 0 white
