Earlier, you read how a bedroom could be used to help someone make a connection to a cell maintaining homeostasis. The door to the room was compared with the cell membrane, and the trash can was said to be like the vacuole that stores wastes in the cell, helping you understand the functions of these organelles. Now, think of another object that could be compared with a cell. Using the space below, be creative as you explain how cellular respiration, diffusion, and waste removal take place in both the cell and the thing to which you are comparing it.

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
