In most hypotheses of early Earth and the formation of life, it is accepted that the atmosphere was a reducing one. This means that there was an abundance of methane, ammonia, and water vapor, but there was an absence of significant amounts of oxygen gas. Based on this assumption, what was likely the first metabolic activity to harness ATP to evolve in primitive cells?A)Photosynthesis, as plants evolved before animalsB)Cellular respiration, as this generates the most ATPC)Glycolysis, as this does not require organelles nor oxygen

Which is not a type of symmetry? a. asymmetryb. radial symmetryc. bilateral symmetryd. lateral symmetry
