Lichens are a mix of two organisms—a fungus and an alga. the alga, by virtue of its ability to carry out photosynthesis, provides food for the fungus. the fungus, in turn, protects the alga by forming a covering over it. what kind of an interaction is being exhibited by the fungus and the alga? a. commensalism b. mutualism c. competition

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
