Answer:
RNA contains an additional oxygen atom on the ribose sugar. (Ans. C)
Explanation:
RNA contains a sugar which is known as ribose, and which contains an extra group of hydroxyl (OH-) while DNA contains deoxyribose sugar.
RNA contains four nitrogenous bases cytosine, adenine, guanine, and uracil, while DNA contains cytosine, adenine, guanine, and thymine.
Double helix means two stranded structure like DNA, while RNA is single stranded.
DNA molecule is much longer polymer than RNA molecule.
The answer is; D
It reduces the diversity of the population because some variations in the population can be completely eliminated by the bottleneck effect. Even if the population recovers in population size, the genetic variation will have reduced as compared to the initial population before the bottleneck. For a mall population, this effect can be grave because the reduced genetic variation may mean that the population may be unable to adapt to new selection pressures hence may go extinct.

From the options what can be said about this disease is that ( B ) : The Pathogen replicates without using host cells' replication machinery and it is directly transmitted.
Since The new disease transmits from one person to another via handshake that means that the disease is a directly transmitted disease, also given that the disease can be cured with the use of antibiotics shows that the causative agent is not a virus but a bacteria. bacteria are living organisms with their own machinery for self replication, therefore they do not need the host cell to replicate the disease before transmission.
Hence we can conclude that the disease is caused by a Pathogen which replicates without using host cells' replication machinery and it is directly transmitted.
