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? Water entered or left the gummy bears so that the concentration of water molecules would be equal in the solution and in the gummy bears.

. Salt entered or left the gummy bears so that the concentration of solute would be equal in the solution and in the gummy bears.

Distilled water was able to be absorbed by the gummy bear, while the solute in the salt water prevented the movement of water.

Distilled water was able to stick to the surface of the gummy bear when it was removed from the beaker, while the salt water was not.

98 points you will be galileo perform the experiment to determine if objects with different mass fall at the same, or different, rates in the air and in a vacuum. before you conduct your experiment, you need to form a hypothesis. a hypothesis is a prediction of what you think will happen in the experiment. the hypothesis is a statement that describes “if” a certain set of circumstances are present “then” there will be a specific result that will occur. record your hypothesis here: record the results from step one of the experiment (dropping the objects in the air): first trial: second trial: third trial: record the results from step two of the experiment (dropping the objects in a vacuum): first trial: second trial: third trial: did the experiment support your hypothesis? using the data from your experiment, describe why you believe your hypothesis was either proven or disproven. what forces were acting on the objects dropped in the air? what force was acting on the objects dropped in the vacuum? part two: comparing forces choose two forces and compare and contrast these forces. you must provide two ways that they are alike and two ways that they are different. you may make a list, write in paragraph form, or make a chart. choose two forces and compare and contrast these forces. these must be different forces than used in the prior question. provide two ways that they are similar and two ways that they are different. you may make a list, write it out, or make a chart.
