homeostasis
paramecium in a hypertonic solution
look at the table and use it to answer the question.
paramecium contractile vacuole contractions
salt concentration outside paramecium contractions per minute
very high 2
high 8
medium 15
low 22
very low 30
what type of graph or chart would best represent the data presented in the table?
a bar graph
a pie chart
a line graph

Explanation:

A bar graph is best for comparing discrete data like different salt - concentration levels and their corresponding contraction rates. A pie chart is for showing parts of a whole, which isn't applicable here. A line graph is better for continuous data over time or a continuous variable, not for distinct categories like these salt - concentration levels.

Answer:

a bar graph
