Assuming that this is the theory of endosymbiotic creation of eukaryotes , it supports it by showing that ancient prokaryotes such as archae have ribosomes that could have joined together, as the theory states to create the eukaryote's ribosomes that they have today (because they're so similar.)
If only one type of tree is planted in an abandoned field, the ecosystem will contrail<span> little genetic variability. This is not a healthy way of planting. This can lead to the total destruction of the trees. I hope that this is the answer that you were looking for and the answer has actually come to your desired help.</span>
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.
