State a prediction that represents the following alternative hypothesis: Green beans have an effect on a person's heart rate.
If green beans have an effect then a person's heart rate will decrease whenever they are eaten.

Using the correct terminology, what is the direction of movement of water through a semi-permeable membrane when one side has fewer solutes (and more water) than the other.
hypotonic to hypertonic (from fewer solutes/more water to more solutes/less water)
