A group of students wanted to learn how the concentration of copper in water affects the survival of tiny aquatic plankton called Daphnia. The students made four different copper solutions: 0% copper, 0.5% copper, 1% copper, and 2% copper. They poured 200mL of each solution into separate beakers and added 10 Daphnia to each beaker. After 5 days, the students counted how many Daphnia were still alive in each beaker. What is the control treatment in this study?

What is the most reasonable explanation of why algae are unlikely to cause human illness and disease?   They are not typically motile.   They obtain their nutrition from the environment.   They are extremely susceptible to digestion by the normal human microbiota.   Their cell wall is easily digested by humans.
