Explanation:
Prey minimize their presence and avoid predators by staying silent, staying in their refuge, and reduce their overall activity levels.
The answer in the statement above is true, it is because it
is necessary to have large sample because diseases are unpredictable, which
will be difficult especially on isolated populations are being considered.
Having an isolated population could be hard to the researches because they only
have a limited people to observe, that is why they needed a large sample in
order to differentiate results and have enough sample to use.

Mutations in the nucleic acid sequence of the gene that can be sometimes direct the substitution of one amino acid for another in the encoded protein. Arginine and methionine amino acid are the substitution that would be most likely to severely disrupt the normal structure of the protein
A genetic mutation is the change to a gene's DNA sequence that produce something different. It also creates a permanent change to that gene's DNA sequence. Genetic variations are the important for the humans to evolve, which is the process of change over the generations. A sporadic genetic mutation may occurs in one person.
