Explain why solvents like water do not disrupt cell membranes

Biology
1 answer:
labwork [276]4 years ago
5 0
Cell membranes are composed of a phospholipid bilayer. The phosphate group of the phospholipid dissolves in the water, as it is polar, allowing the water molecules to surround it. The bilayer is composed so that the phosphates face outwards. The hydrophobic tails of the phospholipids remain inside the bilayer and these do not dissolve in the water. The fact that only the phosphate group of the bilayer dissolves but the tail doesn't means the membrane can maintain its structure.

To make Paramecium Contractile vacuole concentration graph useful the salt concentrations descriptions should replaced with actual values.

Thus, option "A" is correct.

What is Paramecium Contractile vacuole

"It is a sub-cellular structure (organelle) involved in osmoregulation."

<h3>What is a graph?</h3>

"A diagram (such as a series of one or more points, lines, line segments, curves, or areas) that represents the variation of a variable in comparison with that of one or more other variables."

<h3>What does the graph in the given question depict?</h3>

It shows that the Paramecium Contractile Vacuole concentration per minute decreases as salt concentration increases.

But the concentration of salt is not mention in quantity so its not clear what are the lowest and highest concentration affecting Paramecium Contractile Vacuole.

Hence, the Paramecium Contractile Vacuole concentration graph can be more useful if the actual values of salt concentration will be mentioned.
