It is true that it is possible for a population to not evolve for a while.
There is something called the Hardy-Weinberg theorem, which characterizes the distributions of genotype frequencies in populations that are not evolving.
There are 5 Hardy-Weinberg assumptions:
- no mutation
- random mating
- no gene flow
- infinite population size
- and no selection (natural nor forced).
You can see that some of these are kinda extreme and really hard to get, but with approximations, we can work.
For example, instead of an "infinite population size" we have enough with a really large population, such that genetic drift is negligible.
Concluding, yes, it is possible (but really difficult) for a population to not evolve for a while (at least, in nature), as long as the 5 assumptions above are met.

The DNA material found in each person is unique, no two individual have the same type of DNA material. Because of the differences in the DNA molecule of individuals, the restriction enzyme recognition sites are also different too. Restriction enzyme recognition sites refer to the different locations on a DNA molecule which contain specific base pair nucleotide that are recognized by restriction enzymes.<span />
Answer: True
Sometimes the use of condoms can't prevent STIs(sexually transmitted infections) because of the manufacturer fault. STIs that caused by lice is not protected too because the condom doesn't cover hair. Other than that, a condom provides a good physical barrier that prevents diseases that transmitted body liquid.

Answer:
Many cellular processes use similar mechanisms to achieve different goals.
Explanation:
<em>Metabolic pathways are series of enzyme-catalyzed reactions. Enzymes interact to remove and add phosphate groups to molecules or to move protons across a membrane. The same as in cell signalling, where the receptor proteins interact with specific molecules and often remove or ad phosphate groups. The phosphorylation of receptor proteins is very close to the process steps in metabolic pathways but with a very different function. </em>
<em>In metabolism phosphorylation is a method of transferring energy, in cell signalling it transmits information.</em>
