Answer:
when carbon dioxide level goes up.temp. goes down.and vice versa
B. prokaryotes because they do not contain organelles or a nucleus. the following above in the question all are eukaryotic and contain organelles and a nucleus
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.
