Chromosome is to cactus as gene is to needle.
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.
cannot breathe, is not a living organism, doesn't grow doesn't move

Explanation:
<span>Myelination enhances the speed of action potential propagation.
The difference between myelinated and unmyelinated axons are in the propagation of action potential. In unmyelinated axons, the action potential travels continuously through the axons. On the other hand, among the myelinated nerve fibres, transmembrane currents can only occur at the nodes of Ranvier where the axonal membrane is exposed, so the excitation of the axonal membrane jumps from node to node. This propagation is called saltatory conduction and this movement of depolarization wave is much faster than in unmyelinated fibres.</span>
