Which explains a difference between prokaryotic and eukaryotic gene reguation?

A.
Prokaryotes process DNA in the nucleus, so genes do not need to be activated.
B.
Eukaryotic gene regulation is controlled by more than one promoter and one regulator.
C.
Eukaryotes utilize operons, so they do not need to produce sections of mRNA.
D.
Prokaryotes do not have mRNA, so they do not have processes to degrade mRNA.

None of these statements is correct.

A. Eukaryotes utilize operons, so they do not need to produce sections of mRNA. This is not true, because prokaryotes utilize operons.

B. Prokaryotes process DNA in the nucleus, so genes do not need to be activated. This is not true because prokaryotes don’t have nucleus.

C. Eukaryotes express all genes, so gene expression does not need to be regulated. This is not true because eukaryotes express only certain genes, so, the regulation is high.

D. Prokaryotes do not have mRNA, so they do not have processes to degrade mRNA. This is not true because prokaryotes have mRNA.

A scientist look for in a plant that would identify it as a club moss rather than a liverwort.

Fungi are a food source for animals and humans. Fungi produce oxygen to breathe. Fungi destroy rocks and minerals. Fungi are natural recyclers.

when soaked in dilute sodium chloride solution onion gain mass because of the process of osmosis.

 Explanation: Osmosis is a process when there is movement of water from the region of comparatively higher concentration to the region of lower concentration across in a permeable membrane.
