Question
A few of fellow classmates in lab made similar observations as you. They made wet mounts of
Blepharisma and measured their diameters at the beginning of lab and at the end. Knowing that
the water would evaporate over time, thev wanted to see if the diameters of the Blepharisma
would significantly increase over time. Their collected data can be seen below:
