Question

The data in the graph are the result of a paramecium being placed in a hypertonic salt solution.

A graph entitled Paramecium Contractile Vacuole Contractions has salt concentration on the horizontal axis and contractions per minute on the vertical axis. A very low salt concentration has 30 contractions per minute, low: 22, medium: 15, high: 8, very-high: 2.

What change would most improve the usefulness of the graph?
Replace the concentration descriptions with actual values.
Plot contractions per second instead of contractions per minute.
Remove the plotted points and just keep the line.
Remove the name of the organism from the title.
.

Answer 1

the contractions would increase

Step-by-step explanation:

Answer 2

Replace the concentration descriptions with actual values.

Step-by-step explanation:

A graph is used to convey real, accurate and objective information. The use of the description of the concentrations in place of the real values, does not represent an accurate information, but a subjective and imprecise information. For this reason, to improve the quality of this graph and allow the readers to fully understand it, it would be necessary to replace the descriptions of concentration with real values.
