They are pervasive and play many different roles in the marine environment, from being the base of the food chain, controlling much of the flow of marine energy and nutrients, and being essential to the ocean's health.
Answer: D. Current atmosphere CO2 levels would be increasing more slowly.
Explanation: A P E X
Answer:
Electron Transport Chain
In the third stage, electrons from the NADH and FADH2 molecules move to the electron transport chain (ETC). These electrons generate the required power to move protons through the mitochondria into the space between membranes. In the final stage of cellular respiration, oxygen combines with the electrons and protons to form water.
The answer is <span>The respiratory system supplies the oxygen that the cardiovascular system transports to the different cells for the production of energy.
When air enters the lungs (part of the respiratory system), it passes all way to the alveoli, the smallest functional units of the lung. There, oxygen from the air enters the capillaries, the smallest blood vessels, next to the alveoli. Once in the blood stream, the cardiovascular system transports oxygen to different cells where it is used for the energy production.</span>
