1. You have a tube that contain 9 ml of cell suspension. In another separate tube you added 10ul of the cell suspension and 10ul of trypan blue. After that you added 10ul from the second tube to the hemocytometer for counting and you got the figure bellow (blue: dead cells): a. What is the concentration of the cells in the original suspension tube? (show calculations) b. What is the total number of cells in the original suspension tube? (show calculations)

Osmosis

In simple words, osmosis is the slow, gradual movement of a liquid through a membrane. But there are nuances to this process. For instance, there has to be an imbalance in the distribution of solute in the liquid on either side of the membrane, which has to be semipermeable. The liquid in the region with a lower solute concentration moves to the region with a higher concentration, thereby displacing the solution in the process. The objective is to equalize the concentration of molecules on both sides of the membrane; the displacement of liquid can be viewed as a byproduct of this equalization. Since there is no energy required to carry osmosis, it is considered a passive process.
