Answer:
Denitrifcation
Explanation:
<em>Thiobacillus dentrificans</em> is the gram-negative bacteria that is considered the chemoautotrophic according to its mode of nutrition.
The <em>Thiobacillus</em> is now used by the bioremediation scientists in the remediation of the wasteland as its ability to convert the reduces nitrogen forms that are nitrates and nitrites back to its dinitrogen state which escapes back into the atmosphere thus completing the nitrogen cycle.
This process of conversion is known as the denitrification and on the basis of this, the bacteria are named dentrificans.
Thus, denitrification is the correct answer.

Answer:
The correct answer is c.With an RNA virus, radioactive RNA would have been in the final pellet.
Explanation:
Hershey and Chase infected<em> E.coil</em> with bacteriophage which was having DNA as its genetic material. The bacteriophage was labeled with radioactive sulfur and radioactive phosphorus and it was radioactive phosphorus that was found in the bacterial cells or pellet.
As because DNA contains phosphorus, not protein therefore they it was proved that DNA is the genetic material. Similarly, RNA is also a nucleic acid which is genetic material for many viruses and contains phosphorus.
So if Hershey and chase might have chosen an RNA virus then radioactive RNA would have been present in the pellet. So the correct answer is c.
Answer:
While the sun and moon both have tremendous impacts on earth, the sun definitely has the greater impact.
Explanation:
This is because while the moon's gravitational pull has a great effect on the ocean and tides, the sun literally heats up the planet to the exact inhabitable degree, as well as makes up our day/night schedule
