Dominant over the mutant vermilion (bright red) allele. a homozygous wild-type female fly is mated with a vermilion male fly. predict the eye colors of f1 and f2 generations. (assume that the f1 flies are allowed to interbreed to produce the f2 generation.)

4. discuss additional factors that some planets have that affect their seasons. 5. what fact about other planet’s seasons most surprised you and what did you find the most interesting? why?

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
