Mutations can occur at higher rates in viruses.
Explanation:
The mutation rate of an organism refers to the rate or average number of errors which are formed in the genome of the organism’s progeny per base per replication cycle.
Accordingly the Mutations of viruses are the highest per base pair per generation mutation. Viruses can mutate more than a million times than the host’s body due to their virulence factor, evolution ability, and presence of a variety of traits.
Of the DNA and RNA viruses, the RNA viruses like the Retroviruses having a much higher rate, for example, the HIV virus which is a Retrovirus has high mutation rate.
Answer:
more resistant
Explanation:
bedrock is resistant to weathering and erosion
To calculate this we will use the light equation:

λ

We have Frequency

.
We know that speed of light in vacuum is

.
Since a unit of speed of light is m/s, we can change the unit of frequency Hz to 1/s, since Hz means cycles per second (f=1/T).
So:
