Question

the passage below describes an experiment. leo set up six tanks with equal volumes of 20°c water. three of the tanks contained water with a high - salt content of 30 parts per thousand, and three contained water with no salt. leo added an equal amount of green algae to each tank. he allowed the algae to grow in the tanks for two weeks. then he measured the amount of algae in each tank. identify the question that the experiment can best answer. do algae grow more in water with a high - salt content or in water without salt? do algae grown in water with a high - salt content release more oxygen than algae grown in water without salt?

Explanation:

The experiment has two groups - one with high - salt water and one with no - salt water, with algae growth measured. It aims to compare algae growth in these two types of water. There is no measurement of oxygen release in the experiment description.

Answer:

Do algae grow more in water with a high - salt content or in water without salt?
