A team of environmental scientists believes that global warming will have a negative impact on tropical fish populations. They design an experiment to model the effects of global warming. First, they fill two aquariums with salt water and put a dozen tropical fish in each. The water temperature in both aquariums begins at 25 degrees C. Aquarium A is kept at a consistent 25 degrees C, but Aquarium B's water temperature is gradually raised by 1 degree C each week of the experiment. At the end of week 8, 8 of the 12 fish in Aquarium A survived and 9 of 12 fish in Aquarium B survived. The scientists conclude that global warming does not pose a significant threat to tropical fish. What was the independent variable?

Turtle hatchling survivorship rate is low in many turtle species due to predation. amanda researched the predatory rate on a species of turtle eggs in the red river. the eggs were harvested from trapped turtles and the egg's cloaca film (reproductive discharge) was either washed off or left on once gathered. research suggests that predators use the female's cloaca scent to locate the eggs. the eggs were only handled when wearing gloves and then reburied along islands where the turtles were trapped. the nests were monitored by cameras and manually on foot and data on nest predation were recorded. a. based on the experimental design, what is the dependent variable? b. based on the experimental design, what is the independent variable? c. based on the experimental design, what is the control?
