Answer:
Oxygen and pyruvate.
Explanation:
The krebs cycle is a stage of cellular respiration and occurs in aerobic organisms. In this case, we can say that the Krebs Cycle only occurs in the presence of oxygen, being essential for the completion of cell respiration.
The Krebs cycle only occurs after the completion of glycolysis, as it needs to be initiated by pyruvate, which is a molecule resulting from glycolysis. In this case, in addition to oxygen, the presence of pyruvate is essential for the krebs cycle to occur.
Well, I know 4 is A and 5 is D.
All are part of domain Archaea. Archaeabacteria are prokaryotic or no nucleus present and are <span>unicellular organisms. They are often characterized as having the ability to thrive in extreme conditions. Mesophiles are found in high salt content areas. Thermophiles in high temperature areas. Acidophiles in high pH areas.</span>
