Alfred Wallace and Charles Darwin where both the theorists
behind the natural selection mechanism by which animals evolve to adapt in
their environment. Distinctively, Wallace was the co-author of the theory by
which his expeditions made him discover the processes that act on how evolution
occurs which he relayed to Darwin. However, as both peers in the theory of
evolution it seems to have arose that Wallace never became popular on this idea
unlike Darwin.
Answer:
Over our lifetime, our DNA can undergo changes or mutations that result in differences in the DNA sequence and may affect the proteins that are made. Mutations can occur as a natural consequence of errors in DNA replication or as a result of exposure to environmental factors such as smoking, sunlight or radiation.
Explanation:
Answer:
The options
A) T-series bacteriophages
B) retroviruses that require a DNA intermediate
C) single-stranded DNA viruses such as herpesviruses
D) nonenveloped double-stranded RNA viruses
E) linear double-stranded DNA viruses such as adenovirus
The correct answer is B.
B) retroviruses that require a DNA intermediate
Explanation:
Since the baltimore's scheme which was used for virus classifications was included, the most closely likely alternative of virus to the given polio virus that possess a single stranded RNA in these case study is more likely to be retroviruses that needs a DNA intermediate.
Unlike the single-stranded RNA viruses, the retroviruses lack DNA but possess the enzyme called reverse transcriptase used for RNA replication into the host cells DNA and take advantage of the end product for their favour.
I hope this answer helps.
Answer:
mono, di, poly
Explanation:
The smallest molecule would be a monosaccharide because the prefix mono- means one.
The next largest molecule would be a disaccharide because the prefix di- means two.
And the largest molecule would be a polysaccharide because the prefix poly- means many.
