Question

1. make a null hypothesis that compares the osmolarity of the potato and the celery. then predict the data that you would collect that would support your null hypothesis. what is a null hypothesis? null hypothesis: a predicted supporting data: b

Explanation:

A null hypothesis states no difference between tested groups. For osmolarity, it claims potato and celery have equal osmolarity. Supporting data would show no significant mass/volume change when both are placed in solutions of the same osmolarity, or identical isotonic solution concentrations for both.

Answer:

Null Hypothesis: There is no significant difference in the osmolarity of potato tissue and celery tissue.
Predicted Supporting Data: When potato and celery samples are placed in a series of sucrose solutions of varying concentrations, both samples show no significant change in mass (or volume) at the same sucrose solution concentration (the isotonic point), and the calculated osmolarity values for potato and celery are statistically indistinguishable.
