A scientist is comparing ribosomes in a prokaryotic cell and a eukaryotic cell. Which is a property of the ribosomes from the eukaryotic cell only and not the prokaryotic cell? A. Proteins are assembled on ribosomes.
B. Some of the ribosomes are attached to the cell membrane.
C. Some of the ribosomes are located on the endoplasmic reticulum.
D. All of the ribosomes are distributed evenly throughout the cytoplasm.
E. All of the ribosomes are attached to the cell membrane.

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.

Select the correct answer from each drop-down menu. in an experiment, dr. travis examined the effects of calcium intake on osteoporosis, a condition that causes an increased risk of bone fractures. the amount of calcium is variable. the risk of bone fractures .
