If a chemist wants to study dissfusion should a semipermeable membrane be used?
Diffusion is essentially the movement of solute molecules from a region of higher concentration to a region of lower concentration. A semi permeable membrane need not be used to study this phenomenon
What happens to the resting membrane potential if ATP was depleted in a nerve cell?
All active transportation of ions would stop and ions would be allowed to run down their concentration gradients, eventually reaching equilibrium. At this stage there would be no more electrochemical potential difference across the cell membrane.
In which direction would osmosis occur if 15 percent sugar solution is separated from a 25 percent sugar solution?
It would flow toward the weaker solution. The intent of osmosis is to gain equilibrium, so the 15 percent solution would gain sugar content until, if you allowed the osmosis to go to completion, the two solutions had the same amount of sugar in them. "Going to completion" doesn't necessarily mean 20 percent concentration on both sides. If you were to make a gallon bag out of dialysis membrane, fill it with 15 percent solution and put a stirrer in it, then drop it into a 25,000-gallon reaction vessel full of 25 percent solution with a stirrer in it, you might wind up with 24.9999999999 percent sugar solution in both bags.
What organelle moves substances across the cell in one direction?
The plasma membrane surrounding animal cells is where the exchange of substances inside and outside of cells takes place. Some substances need to move from the extracellular fluid outside cells to the inside of the cell, and some substances need to move from the inside of the cell to the extracellular fluid.Some of the proteins that are stuck in the plasma membrane help to form openings (channels) in the membrane. Through these channels, some substances such as hormones or ions are allowed to pass through. They either are "recognized" by a receptor (a protein molecule) within the cell membrane, or they attach to a carrier molecule, which is allowed through the channels. Because the plasma membrane is choosy about what substances can pass through it, it is said to be selectively permeable.
Level of solutes is the same inside and outside of the cell?
This depends on the concentration of the solute(s) involved. If the concentration is beyond the equilibrium point, then it is considered super-saturated and solids will form at the bottom of the flask. If it is an un-saturated solution and the flask is allowed to sit for some time, the solute(s) will sink to the bottom of the flask. Given enough energy (in the form of heat) the solute will begin to move around at a faster rate.
What is a NanoDrop?
A Nanodrop is a Biology Machine that allowed you quantify concentration of DNA in a solution...
What happens when concentration gradient 0?
When the concentration gradient is 0, no flow is allowed to go through the cell wall. To get motion through a membrane, the concentration gradient must be higher than 0.
What would happen to the resting membrane potential of a neuron if sodium were allowed to travel freely down its concentration gradient?
The cell will depolarise

What is the importance of osmosis?
Osmosis, in botany and chemistry, is the process by which some unwanted elements or molecules in a solution are blocked by a membrane that other substances are allowed to pass through.
How does osmosis take up water?
Osmosis is the transfer of a solvent (e.g. water) through a semipermeable membrane from a less concentrated solution on one side to a more concentrated solution on the other side. Osmosis is driven by ordinary statistical diffusion, the same movement of solvent occurs even without the membrane but the membrane prevents other types of mixing (e.g. mechanical, convection) that would allow mixing of solutes in the solutions. Only mixing by diffusion through the membrane is allowed.

What do you call the membrane that allowed the movement of molecule?
