Cell membranes serve as barriers and gatekeepers. They are semi-permeable, which means that some molecules can diffuse across the lipid bilayer but others cannot.
The movement of water molecules in and out of a cell is called osmosis.
Osmosis, or the diffusion of water molecules, is when water molecules flow in or out of a cell from high to low concentrations (down their concentration gradient). The ultimate goal of osmosis is to establish equilibrium between the cell and its outer environment.
Hope this helps!
When writing a hypothesis, you need to be able to say IF this, THEN this will happen.
Answer: D. Exponential
Explanation:
The exponential growth occurs when the resources are unlimited to the population of the species. The population grows rapidly at a constant rate. Thus the population size increases over concerned period of time. When the resources become limited the growth collapses this is called as logistic growth.
The exponential growth can be shown by the J-shaped curve.
i guess there should be some options for this question ...
