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:
Operations of heavy machinery should be avoided.
Vehicles should not be driven at the period of medication.
Intake of alcohol and alcoholic beverages should be avoided 2 hours before intake of the medication,or within 8hrs after drug administration.
All these are essential to avoid accident from possibly drowsiness.
Explanation:
A because the motor of your mower is contributing to the carbon emissions
The SYMPATHETIC nervous system prepares the body to expend energy whereas the PARASYMPATHETIC nervous system allows the body to restore and conserve energy
Answer:
When the diaphragm contracts (it's a large flat muscle), it pulls the lungs down this causing expansion which eventually lead to inhalation of air. If it's injured, then that will be affected.
