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.
Answer:
The correct answer is option c. "old layers of xylem and phloem".
Explanation:
Wood is one important good used for construction obtained from the main substance of the outer layer of the trunk or branches of a tree. Biologically, the outer layer of the trunk of a tree is comprised of the old layers of xylem and phloem, which are dead cells that were part of the heartwood or the centre of the tree.
