A research group has discovered that damselflies, a type of dragonfly, are being infected by a particular type of aquatic protozoan. Both young and adult damselflies are not directly infected by the protozoan but contract the infection from the prey they eat. The graph shows the percentage of adult damselflies infected by protozoans during the summer and early fal

• Infection in embanked ponds increased during the sampling period.
• Protozoans were more common in creek-fed ponds than embanked ponds.
• Protozoans reproduce more quickly in embanked ponds than creek-fed ponds.
• Infection in creed-fed ponds remained constant throughout the sampling period.

An experiment was carried out to determine whether drinking caffeinated soda increases pulse rate. The pulse rates of two groups of people at rest were measured. Group A was then given caffeinated soda and group B was given caffeine-free soda. One hour after drinking the soda, the pulse rates were measured. The participants in the experiment were all the same age, and they were all given the same amount of soda. The dependent variable in this experiment is the

• type of soda given to each group
• amount of soda given to each group
•  pulse rate of each group
• age of participants in each group
