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.

Answer:
Recombinant DNA
Explanation:
Recombinant DNA can be used to change the genetic makeup of a cell, as in adding a gene to make a bacterial cell produce insulin.
Type 1 stools are detached, hard lumps that be similar to nuts that are tough to pass. Type 3 stools are like a sausage, but with pops on the surface. Type 5 stools are mushy blobs with clear-cut ends that are passed effortlessly. Type 6 stools are cottony pieces with raggedy edges.
