A cytologist is examining a tissue under an electron microscope. He notices that the endoplasmic reticulum of each cell is extre

mely rough in appearance and he knows that the rough appearance is because of the ribosomes embedded there. He asks why there are so many ribosomes. You respond, _________.A. This tissue exports lipids and is very involved with mRNA which of course is used in protein synthesis.B. This tissue exports proteins to other areas of the body. C. This tissue exports lipids to other areas of the body.D. This tissue exports various nucleic acids, hence the large number of ribosomes present on the endoplasmic reticulum in each of those cells.

Answer:

B. This tissue exports proteins to other areas of the body.

Explanation:

The endoplasmic reticulum is a tubular, flattened sac-like structure that forms a continuous structure with the nucleus.

The endoplasmic reticulum may or may not be attached to another organelle called the ribosomes. The ribosome is associated with the translation of mRNA molecules to protein synthesis.

As the protein is synthesized, the proteins enter the endoplasmic reticulum which modifies the proteins and then package them for the transport to their destined site.

Since the endoplasmic reticulum is involved in the process of transport as it modifies the protein molecule therefore is most appropriate option.

Thus, Option-B is correct.

There are some similarities between prokaryotic and eukaryotic cells. What structures is found in both prokaryotic and eukaryoti
patriot [66]

Answer:

DNA, ribosomes, plasma membrane and cytoplasm are the structures that are found in both.

Explanation:

Prokaryotes are the organisms that do not have a nucleus and other membrane-bound organelles and eukaryotes have a membrane-bound nucleus and another membrane-bound organelle.  

Apart from this there are some similarities between prokaryotic and eukaryotic cell like both have a highly selective cell membrane, they both have cytoplasm, both have DNA and ribosomes which is responsible for the expression of genes. Therefore DNA, ribosomes, plasma membrane, and cytoplasm are the structures that are common in both prokaryotes and eukaryotes.
