What did the miller-urey experiment demonstrate? A. RNA was the genetic storage material before DNA
B. Eukaryotic cells evolved from prokaryotic cells following an endosymbiotic event
C. Life originated in outer space and was brought to Earth on a meteor
D. Complex molecules can be formed from water, carbon dioxide, methane, ammonia, and hydrogen gas in a reducing atmosphere

Cells tend to have a relatively small and uniform size. why aren’t cells larger?

How did the miller-urey experiment impact the way scientists think about the origins of life? use what you know about the miller-urey experiments to discuss the factors needed for life to arise, and speculate on whether life could arise on another planet.

The endoplasmic reticulum (er) is an organelle in some cells. in these cells, it is continuous with the nuclear membrane and forms a large part of the cell\'s total membrane. sort the phrases below as describing rough er, smooth er, both, or neither. note: if you answer any part of this question incorrectly, a single red x will appear indicating that one or more of the phrases are sorted incorrectly.1) found in prokaryites and uekaryotys2) involved in protein synthesis3) involve in lipid synthesis4) contains molecular chaperones in lumen5) bound with ribosomes6) involved in toxin or drug metabolism7) large systemot internnected tubules,vesicles, and sacs8) "packages" enzymes in vesicles for secretion.
