I believe it's oxygenated or oxygen rich blood away from the heart.
Yes, because it would be like shoving something into a crowed place, rather than shoving something into a uncrowded place.<span />
The correct answer is option D, Temporal isolation
Temporal isolation is the mechanism which prevents the mating of closely related species living in the same ecosystem. Basically the reproductive barriers prevent these species from interbreeding. Temporal isolation is a prezygotic barrier that causes “time isolation” between the breeding period of two closely related species. The difference in time could be “difference in time of day”, “ difference in season of mating”, “difference in months” and in some cases “ difference in years”.
Antibiotics are powerful medicines that fight bacterial infections. Used properly, antibiotics can save lives. They either kill bacteria or keep them from reproducing. Your body's natural defenses usually take it from there. Antibiotics do not kill viruses.
The emergence of resistance is a result of EVOLUTION by natural selection. It is a major evolutionary force.
<h3>Evolution and natural selection </h3>
The term evolution refers to the biological process of descendence with modification.
Natural selection refers to the differential survival or reproduction of the organisms better adapted to a given environment.
In this case, the presence of the pesticide generates an evolutionary constraint, thereby selecting pesticide-resistant individuals in the population.
