Question

Which of these processes is a nearly universal energy-releasing metabolic process that indicates common ancestry for all life on earth?

Answer 1

Answer:

glycolysis

Explanation:

Glycolysis is anaerobic, so no oxygen is required. glycolysis is the process in which glucose is broken down by enzymes, thus  releasing energy and pyruvic acid. All cells can perform anaerobic respiration by glycolysis.

Answer 2

The Sun is the star at the center of the Solar System. It is a nearly perfect sphere of hot plasma, with internal convective motion that generates a magnetic field via a dynamo process. It is by far the most important source of energy for life on Earth.
