The answer is C hope this helps
Answer:
There are 40 electrons and protons and 50 neutrons
Explanation:
The correct answer is B. Electron transport.
The electron transport chain is the terminal step of aerobic respiration. It occurs on the inner membrane of the mitochondria. Reduced coenzymes NADH and FADH₂ are produced during glycolysis and Krebs cycle. When NADH and FADH₂ move along electron transport chains, high-energy electrons are released from NADH and FADH₂ produce ATP. The final electron acceptor in the process is free oxygen. Each NADH produces 3 ATP and each FADH₂ produces 2 ATP. Therefore, a total of 32 ATP molecules are generated in electron transport. Therefore, the electron transport system releases a lots of energy for cheetah to run fast.
I would say D, examples of natural selection.
