Can atp production take place in chloroplasts in the absence of light? why or why not? atp production can proceed as long as there is a hydrogen ion gradient across the thylakoid membrane. chlorophyll antenna complexes must be active for the redox reactions of electron transport to be functional. the energy required for the phosphorylation of adp in chloroplasts can be supplied only by photon absorption. photons are absolutely required for photosynthesis to work.

Ascientist and her team counted 200 individual deer in an area of 10 square kilometers. what is the population density?

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?
