Choice D would be your answer
Answer: it produced oxygen as a waste product
Explanation: there was more free oxygen
Answer:
In the 1960s, scientists found evidence that new material is indeed erupting along mid-ocean ridges. The scientists dived to the ocean floor in Alvin, a small submarine built to withstand the crushing pressures four kilometers down in the ocean. In a ridge’s central valley, Alvin’s crew found strange rocks shaped like pillows or like toothpaste squeezed from a tube. Such rocks form only when molten material hardens quickly after erupting under water. These rocks showed that molten material has erupted again and again along the mid-ocean ridge.
When scientists studied patterns in the rocks of the ocean floor, they found more support for sea-floor spreading. You read earlier that Earth behaves like a giant magnet, with a north pole and a south pole. Surprisingly, Earth’s magnetic poles have reversed themselves many times during Earth’s history. The last reversal happened 780,000 years ago. If the magnetic poles suddenly reversed themselves today, you would find that your compass needle points south.
Explanation:
I found this somewhere.
The cell that provides life with chemical energy. Light energy is converted by photosynthesis into chemical energy that is stored in glucose, and this energy is then released during cellular respiration to create ATP.
<h3>What does the term "cellular respiration" mean?</h3>
While cells are aerobic respiration, oxygen may be present or not. But, because the cell seems to "respire" by consuming molecular oxygen (as an electron acceptor) and releasing carbon dioxide, the process is essentially known as "cellular respiration" (as an end product).
<h3>What happens during cellular respiration?</h3>
ATP is created during cellular respiration as a reaction product between glucose and oxygen. Water and carbon dioxide are released as by products. The three stages of aerobic cellular respiration are glycolysis, an anaerobic process, and the Krebs cycle.
