5b. When a tick sucks in a blood meal that contains Lyme disease bacteria, at first these bacteria live in the tick’s gut where the bacteria get nutrition from the blood meal. When the tick begins its next blood meal, the Lyme disease bacteria move from the tick's gut to its salivary glands. Why is this ability to move to the salivary glands a needed adaptation for Lyme disease bacteria? What would happen to any Lyme disease bacteria that were unable to move from the tick's gut to its salivary glands?

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
