Answer:

Read the description of the experiment, then answer the questions that follow.

a) Is the microbiologist’s hypothesis testable? Why or why not?

A microbiologist studying bacteria hypothesizes that a colony will double

in size overnight if she increases the temperature of their surroundings

by 10 C from 25 C to 35 C.

She increases the temperature before leaving for the day and checks the

colony the next morning. She observes that the size of the colony is the

same size as it was the day before, despite the change in temperature.
