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.

A researcher is examining the distribution of an ion channel protein in the kidney. She incubates slices of kidney tissue in a dilute solution of a specific antibody directed against the protein, then uses the immunoperoxidase method to localize the ion channel proteins.

People infected with SARS-Cov-2(the cornavirus that causes covid-19) can show an array of different symptoms and comlications. One complication occurs in the same patients is the development of blood clots throughout the body. Thevirus can infect endothelial cells. How are endothelia involved with blood clotting? If you were to design a pharmaceutical (medication) taht reduced blood clotting, how might it work? There are many ways to approach this question.
