The deep water of a lake's profundal zone is called the epilimnion water temperature is briefly uniform at all depths, and winds create vertical currents during the spring overturn at the water temperature changes abruptly over a narrow depth range. thermocline the epilimnion cools, becomes denser, and sinks, eliminating the thermocline during the hypolimnion the top layer of the limnetic zone is called the and is heated by the sun in summer. fall overturn

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
