Answer: Because every zone of the ocean has the combination of the organisms living there that are adapted to the light, pressure, and temperatures.
Astronomers define star<span> brightness in terms of apparent </span>magnitude<span> (how bright the </span>star<span> appears from Earth) and </span>absolute magnitude<span> (how bright the </span>star<span>appears at a standard distance of 32.6 light years, or 10 parsecs).</span>
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:
Usually contains a large amount of a matrix.
