it is the example of scavenger
Answer:
1 day.
Explanation:
From the given information:
The rate of mutation induced by RNA polymerase is:

Since the genome comprise of 19000 bp;
To complete a single replication, the viral cycle induce: 

However, in a single day; 10,000,000,000 viruses are reported to be replicated.
Hence, if a virus has 2 mutations; Then 10,000,000,000 virus will have:

SO, to round this up to whole number, it will take 1 day (s) to overcome the therapy.
Answer:
The correct option is 'the ability to absorb other cells gave some prokaryotes a survival advantage.'
Explanation:
The scientists have brought forward the theory of endosymbiosis which explains how eukaryotic cells evolved from prokaryotic cells. According to this theory, the scientists claim that the organelles found today in the cells, once existed as individual prokaryotic cells. These organelles were engulfed by larger prokaryotic cells with time and hence, the eukaryotic cells evolved from these prokaryotic cells. The larger prokaryotes might have engulfed the smaller cells for survival.
Answer: c not all cells have a nucleus (prokaryotic cells don’t)
