Which of the following took advantage of the presence of free oxygen in the oceans and atmosphere? a. the evolution of cellular respiration, which used oxygen to help harvest energy from organic molecules b. the persistence of some animal groups in anaerobic habitats c. the evolution of photosynthetic pigments that protected early algae from the corrosive effects of oxygen d. the evolution of chloroplasts after early protists incorporated photosynthetic cyanobacteria

Hello, everyone here? We have a question that says the great oxidation event resulted in the evolution of cellular respiration and organisms due to the availability of which of the following gasses a carbon dioxide, be nitrogen, see oxygen or D. Methane. So what happened during the great oxidation event during the great oxidation of an oxygen dip laced methane in the environment and became essential to the Earth's atmosphere? And what does oxidation mean? Oxidation refers to oxygen? So our answer here is C oxygen. Thank you for watching. Bye.
