Oxygen would be the best 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.

The answer is A.
The cuticle is a protective film that is non cellular covering the outer cell layer (epidermis) of green, aerial parts of plants. Cuticles protect plants against drying (desiccation), UV radiation, and various kinds of physical, chemical and (micro)biological agents.
The cuticle also provides some support. Actually the cuticle which protects the underlying tissues has basically the same function as our own skin.
In several groups of plants, cuticles are very resistant. Only few groups do not generally have highly resistant cuticles e.g. ferns and lycopods.
The term for the type of key that biologists used in separating<span> groups of organisms that are based on couplets is called taxonomic key. This key is very useful in the identification and classification of a </span>specific organism and it usually has an analytical characteristic.<span> </span>
