Two pure-breeding mutant plants produce white flowers. when they are crossed, all of the progeny have wild-type purple flowers. What does this genetic complementation test tell you?

A. The geners are part of distinct biosynthetic pathways

B. the two lines exibit different mutations in the same gene

C. more than one gene is involved in determining the phenotype

D. the allele is pleiotropic

E. The allele exhibits incomplete dominance

When in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? view available hint(s)when in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? active transportexocytosis
