If rates of nitrogen fixation increased tenfold in aquatic ecosystems, would you expect a tenfold increase in primary productivity? no, because the increase in primary productivity would be greater than tenfold yes, because nitrogen is a limiting nutrient in aquatic ecosystems yes, because there is an abundance of dissolved carbon dioxide in aquatic ecosystems no, because there are other limiting nutrients in aquatic ecosystems besides nitrogen

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
