Answer:
Humans can have a major impact on freshwater systems through water overuse. The same waterways that support wildlife and plants also provide municipal water for cities and towns, and when consumption outstrips the natural regeneration of these waterways, it can negatively affect the ecosystem.
Explanation:
I would say the first option
is because this process involves mitosis in the cells. Mitosis is the occurrence of the cell division that is why the organisms grows and this is not influence by the size of a single cell but the number of cell and cell division progression course.
Answer:
A
Explanation:
It's passive transport because it does not require energy, i.e. you don't need to invest ATP to make it happen. Osmosis is the movement of water from area of higher solute concentration to area of lower solute concentration. It happens via channel proteins called aquaporines. Simple diffusion is when gases like O2 or CO2 difuse through the cell membrane. Again, they go from area of higher concentration to area of lower concentration. Facilitated difusion is how large and polar molecules go in and out of the cell. This happens via transmembrane proteins down the concentration gradient (from higher to lower concentration).
