A student is investigating the responses of plants to their environment. As part of the investigation, he studies a plant that receives sufficient water and has straight, upright stems and firm leaves. He also studies another plant that was grown in dry soil, and has wilted stems and
leaves. Next, the student examines the cells of the plants under a microscope. Which cellular organelle will display the greatest difference
between the two plants?

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
