MARK THIS AS THE BRAINLIEST!
Answer:
I would say that the best answer is A.
Explanation:
Both Bacteria and Archaea, lack a nucleus and are unicellular. Most Archaea have a Cell wall, however there are a few exceptions, all Bacteria have a cell wall. Maybe the biggest difference between the two however, is where they thrive. Archaea live in extreme conditions, while bacteria don't. Due to this, I would say that the best answer is A, because this is the only question with a major difference in answers.
But roughly 2.45 billion years ago, the isotopic ratio of sulfur transformed, indicating that for the first time oxygen was becoming a significant component of Earth's atmosphere, according to a <span>2000 paper in Science</span>. At roughly the same time (and for eons thereafter), oxidized iron began to appear in ancient soils and bands of iron were deposited on the seafloor, a product of reactions with oxygen in the seawater."What it looks like is that oxygen was first produced somewhere around 2.7 billion to 2.8 billon years ago."It looks as if there's a significant time interval between the appearance of oxygen-producing organisms and the actual oxygenation of the atmosphere."
Answer:
Cells will progress through mitosis even when they are not ready.
Explanation:
Being a protein, cyclin controls the progression of cell in the cell cycle, when its concentration will be more it activates cyclin dependent kinase enzyme which are necessary in the synthesis of cell, hence mitosis occurs even when it is completely not ready for it. In this condition cytokinesis will not occur and hence mitosis will occur in which the cell will divide with more than one nucleus. This type of cells are called multinucleated cell.
