Nuclear energy is a non-renewable energy source because the fuel it takes to produce the energy (usually uranium or plutonium) is rare.
Answer:
Chlorplast plays a major role in photosynthesis. It can’t be all organisms since we humans don’t have chlorplast. Some aquatic organsisms uses chlorplast but not all, so the best answer here is A, Photosynthetc organsims.

The meselson-stahl experiment demonstrated that dna replication produces two DNA molecules each composed of the nitrogen isotopes.
<h3>
What was the conclusion of the meselson-stahl experiment?</h3>
Based on observations and experimental results, Meselson and Stahl concluded that DNA molecules can reflect semi-conservatively. Investigation of semi-conservative nature of replication of DNA or the copying of the cells, DNA failed to cease there.
1958, Matthew Meselson and Franklin Stahl carried out an test on E. coli which divides in 20 minutes, to take a look at the replication of DNA. 15N (heavy) and 14N (normal) are isotopes of nitrogen, which may be outstanding primarily based totally on their densities through centrifugation in Caesium chloride (CsCl).
