Explanation:
But, if you are referring to the most widely accepted theory:
Anthropogenic (man-made) Global Warming, or AGW. The theory states that man-made greenhouse gases, primarily carbon dioxide (CO2 ), are the predominant cause for the global warming that has occurred during the past 50 years.
Answer:
All of the above
Explanation:
Carbon atoms are created during the process of photosynthesis. During this process, plants will absorb carbon dioxide and sunlight to create energy, glucose, and other sugars. And for the physical changes of carbon molecules, carbon can undertake multiple changes overtime. Even though this element can be stored in the Earth for millions of years, it can be transferred in seconds from one object to another
Answer:
Water
Explanation:
Molecular oxygen is the terminal electron acceptor and serves to receive electrons from reduced NADH and FADH2 to reoxidize them. NADH and FADH2 are formed during glycolysis and Kreb's cycle. These reducing powers should be re-oxidized to enter in the first two steps of aerobic respiration again.
For the purpose, NADH, and FADH2 transfer their electrons to the molecular oxygen via electron transport chain. After accepting the electrons, molecular oxygen is oxidized into the water molecule. Therefore, radioactive oxygen isotope would appear in the form of a water molecule after completion of cellular respiration.
