Why can't astronomers measure the parallax of a star that is a million light years away?
motikmotik

One of the methods used widely to calculate the distance of nearby or closer objects in astronomy is Parallax. The distance of the stars are usually expressed in light years but the unit of distance is parsec or parallax second.  

                                        1 Parsec = 3.26 light years

Astronomers are not able to measure the parallax of a star that is a million light years away because the star is too far and the distance with which the start appears to move is too less to be calculated accurately.

In eukaryotic cells, the message from the DNA must be removed from the nucleus before it can be read and used to make proteins.
Crank

Answer:

The correct answer is A protein production can occur much faster in prokaryotic cell since the cell does not have to get the message stored in the DNA out of the nucleus.

Explanation:

protein biosynthesis or translation occur in both Prokaryotes and Eukaryotes.

                In prokaryotic cell both transcription and translation occur inside the nucleus but in case of Eukaryotic cell transcription occur in the nucleus whereas translation occur in the cytoplasm.

         In case of eukaryotic cell mRNA processing occurs which involves 5 prime capping, 3 prime tailing and splicing but in case prokaryotic cell no such processing occurs.

                  As a result protein production occur much faster in prokaryotic cell than that of eukaryotic cell.
