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.

True, plants undergo cellular respiration because they need ATP.
Plants are known as primary producers in the ecosystem because they are able to directly harness the energy from the sun and convert it into complex energy molecules. This process requires ATP.
On the other hand, plants also undergo cellular respiration which is the process by which ATP is produced because the plant also needs ATP to perform the functions of cells.
