Density-dependent limiting factors are non living and biotic factors that affect the size and growth of a population based on the population density, while density-independent limiting factors are those factors that do not depend on the density of a population before they can have an effect on the growth and size of the population.
Examples of density-dependent limiting factors are predation, disease, Parasitism, competition. These rely on the density of a population in order to affect the growth and size of a population.
On the other hand, examples of density-independent limiting factors are pollution, flood, temperature.
A biologist researching liver function in mice can administer drugs that are meant for human use to the rats and find out the effects this drugs will have on the rats' liver. Whatever result she find can be extrapolated to humans.
Thus, the biologist can contribute to medial advancements by using her findings to predict the effects of these drugs on human livers.
