Answer:
C
Explanation:
It moves across the cell membrane via simple diffusion, a process that requires no energy input and is driven by the difference in concentration levels on each side of the cell membrane.
Hii!! I believe the correct answer is C. the predator captures the organism very fast and easy. (:
The body of water experiences eutrophication.
The process of eutrophication takes place primarily in ecosystems with gradual changing waters, mainly in deep lakes. In the depths of the lake, where deposition of dead algae takes place, the aerobic bacteria, which feeds on them proliferate that in turn consumes more amount of oxygen.
Though in the absence of enough circulation of water that is usually found in the case of deep lakes, the bottom of the lake is poorly oxygenated and the bacteria eventually deplete the oxygen found in the deep layers of water. Thus, they can no longer degrade all the dead organic matter and gets accumulated in the sediments. The lake is now considered to be aging.
Explanation:
Cell membranes are selectively permeable. Some solutes cross the membrane freely, some cross with assistance, and others do not cross at all. A few lipophilic substances move freely across the cell membrane by passive diffusion. ... Large molecules do not cross intact cell membranes, except in certain special cases.
A nucleus cell contains chromosomes among other things.
