The higher per-site mutation rates of RNA viruses can be explained in part by the RNA-dependent RNA polymerases (RdRp) that replicate their genomes. Unlike many DNA polymerases, RdRp do not have proofreading activity and are thus unable to correct mistakes during replication.

The cheetah population was around 100,000 in 1900. Today, fewer than 12,000 cheetahs remain. What type of natural resource are c
sasho [114]

Non-renewable resource

Explanation:

The cheetahs can be considered a non-renewable resource. Non-renewable implies that a resource cannot be replenished at it current rate of depletion.

How much has the cheetah's population declined:

         percentage declination = \frac{Population in 1990}{Population today} x 100

Population in 1990 = 100,000

Population today = 12,000

  Percentage declination = \frac{100000}{12000} x 100 = 83.3%

We can see that the cheetah has suffered a whooping 83.3% decline in their population.

A renewable resource is one that can be replenished as it is being used such as water, air, e.t.c.
