Bees pollinate red snapdragons in one part of the garden then fly over to another area and pollinate white snapdragons. after a few generations, the seeds from the white snapdragons start to produce pink snapdragons. identify the mechanism that brought this change in gene frequencies. select one of the options below as your answer. a. genetic drift. b. gene flow. c. reproductive isolation. d. disruptive selection.

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
