The cell membrane is made up of lipid bilayer and proteins are embedded or may span the lipid bilayer. The carbohydrates are present in association with lipids and proteins.
The artificial membrane has been prepared that are free from proteins. Small uncharged particles may easily diffuse through the membrane. Among the given molecules in the question water is the smallest molecule and diffuse out first through the plasma membrane. Ethanol is 2 carbon compound and diffuse after water than glycerol diffuses as it is a 3 carbon compound. Glucose is the largest molecule and diffuse last through the plasma membrane.
Thus, the correct answer is option (A).
Yes the penguins and bears and pandas
Embryo undergoes mitotic divisions throughout its development. Since the number of cells increases with each mitotic division, it is important all of them to persist in normal cell division. That way the embryo development will end successfully when a baby is born. But, if all cells of the embryo fail to go through S phase, the DNA will not replicate. As mentioned, DNA replication occurs in the S phase of mitosis. <span>A cell cycle will be interrupted and the mitotic divisions will stop. Consequently, the embryo will die.</span>
