In unit 1 we will be looking at cells. Cells make up all living things. If something has cells, it's a living thing. If something does not have cells, it is not a living things. We will also look at some key parts inside of cells allow them to function.

Finally, we will explore some easy differences between animal and plant cells. im stuck on thi

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
