Passage II

An experiment was conducted to determine how seawater temperature and salinity affect food consumption and growth in Scophthalmus maximus (a species of fish). The table shows, for each of 8 trials, average total food consumption, CT, and average gain in body mass for S. maximus kept at various temperature and salinity combinations. Each trial involved the same number of fish and lasted the same number of months.

12. What was the average CT, in kilograms (kg), for fish kept at a temperature of 22°C and a salinity of 25 ppt?

Answer and Explanation

Your Answer is

Correct Answer is F

Explanation

Look at the first and second columns of the picture, and find that the corresponding Trial with a temperature of 22 degrees and a salinity of 25ppt is Trial 2. The Ct value of this trial is 52.1g. Convert it to kg according to the unit of the question, and the answer is 0.0521 kg.
