Answer:
All eukaryotic cells have a membrane that covers them, internal fluid and a central nucleus, so the correct answer is option d (All of the above).
Explanation:
Eukaryotic cells are those that possess a plasma membrane that surrounds them, acting as a semi-permeable membrane to the passage of substances, in addition to possessing the capacity to receive external signals.
The cytoplasmic membrane of eukaryotic cells is related to an endomembrane system, associated to cytoplasmic organelles and to the central nucleus, which stores genetic information, in the form of DNA.
The eukaryotic cell cytoplasm is fluid and serves as a support for the organelles, as well as all the chemicals suspended in it.
<u>The existence of true nucleus and organelles is what defines a eukaryotic cell and differentiates them from prokaryotic cells</u>.
The right answer to this question is option A. O2 in the atmosphere.
The main reason why it's a true that organisms would grow larger than we have today with more oxygen available is pretty simple to understand, their respiratory systems were smaller than we have today, and even though it was a small one, it was enough because of the higher presence and concentration of O2 in the atmosphere.
Some studies were held nowadays to check this possibility, to see if the O2 was the real main reason for this, and the animals used in it really grew bigger than usual, so by that, they confirmed their hypothesis by testing it.
