Which statement most completely describes the primary role of the cell in a multicellular organism?

A. The combination of chemical functions and genetic material enable the cell and the organism to live, grow, and reproduce.

C. The internal structures provide shape and support to a variety of living organisms—both unicellular and multicellular.

D. They help scientists classify all living organisms by the types of cells they are made of.

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
