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.
.

Replace the concentration descriptions with actual values.

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.

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.

correct answer: false

while planning water activities, it is very important to consider the weather, because if we do not plan and are going for a surf, then it might be that the hurricane came and drown us or may carry us to long distance from where we can not come back. there are many reasons to take information about the weather when we are planning any water activities.

hence, the correct answer would be false.
