If carbon dioxide molecules are shown moving from one side of the medium to another, as in this diagram, which process best describes the reverse of this process?
a. osmosis
b. diffusion
c. plasmolysis
d. active transport submit hint cells (sb1.d.) role of water and homeostasis

d. active transport 

An active transport is the process by which a substance is transported or transferred from one area to another using a chemical energy in the course. 

As oppose to passive transport, active transport’s key to its description uses energy to be able to transfer the said substance. This is important in a lot of aspects such as providing the needed elements or compounds in cellular activity. 

The answer to this will be from your lab notes/procedure. it would be best to ask another student who participated in the lab as we do not know what was done, what enzyme or if the temperature is celsius or fahrenheit. if i were to guess though i'd say the rate stopped due to enzyme denturing at high temperature
