Need help with question 23. Which is an appropriate conclusion for the data shown?

The decrease in carbon dioxide (CO2) for the leaf was less than the decrease for the stem.

- More oxygen was produced in the stem than in the leaf.

-There was no photosynthesis taking place in the roots.

- The stem was performing photosynthesis at a faster rate than the leaf.

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?
