Dumping raw sewage into a river will reduce the amount of dissolved oxygen in the water. What effect could dumping raw sewage most likely have on a river ecosystem?
O an increase in cellular respiration due to the rising level of phosphates in the water
O a decrease in water temperature due to the energy transfer from osmosis
O a decrease in aquatic animal populations
O an increase in fish populations

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
