36. 18. Temperature affects the development of sea-turtle eggs
18. Temperature affects the development of sea-turtle eggs. Eggs that are incubated at warmer temperatures are more likely to become females. Eggs incubated at cooler temperatures are more likely to become males. How would higher atmospheric carbon dioxide concentrations most likely affect sea turtle populations?
Earth’s climate would be warmer, so the percentage of female turtles would increase.
Earth’s climate would be cooler, so the percentage of female turtles would increase.
Earth’s climate would be cooler, so the percentage of female turtles would decrease.
