Explanation:Earth’s core that cause the molten rock in the mantle layer to move, and it moves in a pattern.
well It is generally believed that the energy-converting organelles of eucaryotes evolved from procaryotes that were engulfed by primitive eucaryotic cells and developed a symbiotic relationship with them. This would explain why mitochondria and chloroplasts contain their own DNA, which codes for some of their proteins......
DescriptionNitrification is the biological oxidation of ammonia or ammonium to nitrite followed by the oxidation of the nitrite to nitrate. The transformation of ammonia to nitrite is usually the rate limiting step of nitrification. Nitrification is an important step in the nitrogen cycle in soil.

Answer:
The correct option is <em>E. Amino acids (and thus proteins) also have nitrogen atoms; thus, the radioactivity would not distinguish between DNA and proteins.</em>
Explanation:
The element phosphate is actively present in the DNA but it is not present in the proteins.
Nitrogen is an active constituent of the DNA as well as the proteins. Hence, if nitrogen will be used for the Hershey and Chase experiment, then the results will that we will get will be wrong. We wouldn't be able to distinguish between the nitrogen atoms which came from the DNA and the nitrogen atoms which came from amino acid or proteins.
