A student carries out an experiment to investigate the role passive transport plays in maintaining homeostasis in organisms. For this investigation, the student uses two gummy bear candies to represent animal cells. The student records the mass of each bear. Then, he places one in a beaker filled with distilled water. He places the other in a beaker filled with salt water. After 48 hours, he removes the bears from the beakers and records their masses again. He finds that the mass of the gummy bear in the distilled water significantly increased, while the mass of the gummy bear in the salt water significantly decreased. Which of the following is the best interpretation of the observations made during the investigation?
