What component surrounds the cell and separated the cell from its environment?
The cell wall or membrane keeps it separate from the environment.
Where is the net movement of water in a hypotonic solution?
no Water will move freely between the two solutions if they are separated by a selectively permeable membrane. However, there will be no net change in the concentration of water on either side of the membrane. Differences in solute concentration will allow you to predict net changes in water movement.
Does water flow from Low Osmolarity to High Osmolarity?
yes, water flows from low osmolarity to high osmolarity when two solutiona are separated by a semi-permeable membrane till the solutions on either side of the membrane attains equal osmolarity.
Is the cell wall entirely separated from the plasma membrane in plants and bacteria?
Yes, the cell wall is entirely separated from the plasma membrane in both plants and bacteria. In plants, the cell wall is composed of cellulose and other polysaccharides and provides support and protection. In bacteria, the cell wall is made up of peptidoglycan and serves as a protective barrier.
What keeps cells contents separated from external environment?
Cell contents are separated from the external environment by the cell membrane. Cells are also separated by the external environment when they are in the bloodstream in the capillaries and veins.
When the concentration on molecules on both sides on the membrane the molecules will?
Osmosis only occurs when the concentration of solutions are different when separated by a membrane. If both solutions are of the same concentration, Osmosis will not occur, so there will be no change.
When does osmosis occur?
When two solutions, with different concentrations are separated by a semi permeable membrane. The flow will be from high concentration to low.
If the concentrationof molecules on both sides of a membrane is the same the molecules will?
When the concentration of molecules on both sides of a semi permeable membrane are the same, there is no concentration gradient. Therefore, the system is at a state of equilibrium and the molecules remain static
What are the requirements for materials?
Osmosis occurs when there are two solutions of different concentration strength separated by a semipermeable membrane. The membrane must allow water to cross, but not the solutes. Water will then move from the solution of lower concentration strength across the membrane to the solution of higher concentration strength. This movement of water is called osmosis.

What is osmosis controlled by?
Osmosis is controlled by the permeability of the osmotic membrane and the equilibrium of the solutions on either side of the membrane. If the solutions have unequal concentrations or osmotic pressures, and the molecules in the solution can pass through the membrane, then the solutions will mix until both sides have equal concentrations. If the membrane is impermeable, then nothing will happen.

What unit of living matter separated from its environment by a membrane?
Cell
What two lateral ventricles are separated by a thin membrane?
arachnoid
Does water flow from Low Osmolarity to High Osmolarity?
yes, water flows from low osmolarity to high osmolarity when two solutiona are separated by a semi-permeable membrane till the solutions on either side of the membrane attains equal osmolarity.
How is the nucleus of a cell separated from the cytoplasm?
The nucleus as a whole is not separated from the cytoplasm, which surrounds it. However, the contents of the nucleus (DNA and assorted proteins) is separated from the cytoplasm by the nuclear membrane (a.k.a the nuclear envelope), which is the outer portion of the nucleus.
