WILL GIVE BRAINLIEST!! PLZ HELP ASAP!!
A scientist performed an experiment on a species of small freshwater fish to determine their behavioral responses to different water temperatures. Twenty fish were each tested once, one at a time.

To begin the experiment, one fish was removed from a stock tank (with a constant temperature of 21°C) and placed into a temperature-gradient tank. In the temperature-gradient tank, there are five sections, each maintaining a different temperature. After 30 minutes, to give the fish a chance to acclimate to the new tank, the experimenter would record the section where the fish was located. Six more observations were made for this fish, at five- minute intervals. This same procedure was repeated for the other 19 fish. The results of the experiment for all 20 fish are summarized in the data table below:

Section Fish Per Section
A 18
B 22
C 68
D 24
E 8
A) Summarize the outcome of the experiment.

B) Identify two variables that were not specifically controlled in this experiment and describe how each variable may have affected the results.

C) Discuss ONE way in which temperature could affect the physiology of the fish in this experiment.

B) one variable that was uncontrolled was that fish were not forced to go into a certain section. They had a chance to accumulate by themselves. If this was controlled, fish wouldn’t be able to adjust by themselves, they would be forced in a section they might not accumulate well in. Another uncontrolled variable would be amount of food you give them. This affects the result because if you don’t feed them, they will die. If you feed them too much, they over eat and die. C) The temperature can affect the physiology because if it is too cold for the fish, they will go to another section until they are warm. If it is too hot for the fish, they will go somewhere cooler.

Explanation:

I explained everything already. Please can I have Brainliest? I spent a long time doing research on this and this took 40 minutes so your welcome lol. I hope this helps you!!(can i have brainliest)❤️❤️
