Answer 4 questions

I need an explanation for this Biology question to help me study.

Post a thread with answers to the following questions:

A student studying aquaculture is interested in how diet and water temperature affect the growth rates of fish. She hypothesizes that fish receiving a high protein diets and in warmer temperatures will have enhanced growth rates.

She has four treatment groups:

  • Fish tanks in a laboratory at 22 degrees C and high protein diet.
  • Fish tanks in a laboratory at 22 degrees C and low protein diet.
  • Fish tanks outside with a temperature of 26 degrees C and high protein diet.
  • Fish tanks outside with a temperature of 26 degrees C and low protein diet.

Is her hypothesis a true hypothesis or merely a prediction? (Has she provided rationale for her hypothesis?)

Do you think this is a good experimental design? Do you have suggestions for how she could improve her experimental design?
