Plants, bison, elk and wolves are all members of an
ecosystem. The bison and elk are both primary
consumers in this ecosystem, while the wolves are a
predator. Over time, the bison completely
disappear. Give an example of how the ecosystem
may respond to this change, and explain how this
relates to both resiliency and biodiversity. (4 points)

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
