10. Contaminated surface water can eventually enter groundwater and contaminate it. 11. Depending on the type of soil or rock, groundwater will flow at different rates. 12. Rain and snowmelt infiltrate (seep) into the ground to become groundwater. 1. False.
Water can move through the cell membrane directly through the membrane (simple diffusion) or through protein channels called aquaporins. Explanation: Small molecules such as water and carbon dioxide can pass directly through the membrane because of they are neutral and so small. The movement of water through the membrane is referred to as osmosis. The movement of water through the plasma membrane depends on the construction of the membrane. For example, a membrane which has a lot of cholesterol incorporated in the membrane will not allow water to pass as easily through it. A membrane with less cholesterol will have a greater permeability for water.
