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.

Answer:
B
Explanation:
Rabbits are primary consumers because they eat producers/plants.
Explanation:
Water molecules are polar, meaning they have dipole polarities. The Hydrogen end is partially positive while the Oxygen end is partially negative. This is due to the fact that oxygen has a higher atomic mass and hence attracts most of the electron cloud of the molecule towards its end.
This property of water is very important because it is able to dissolve polar molecules while non-polar molecules do not dissolve. This is an important property in the body of organisms because, for example, water helps in the folding of proteins (by interacting with polar motifs of a protein) hence ensuring the protein maintains their functional structural forms.
Water also dissolves significant polar molecules that are utilized by the body, such as glucose, and helps in their transportation within the body. Water is also significant in the diffusion of hormones used in cell signaling, e.t.c.
Water is also able to dissociate ionic compounds, such as sodium chloride, that are important in the osmotic pressure homeostasis of cells.
