Answer:
A malaria outbreak causing allele frequencies to change is an example of <u><em>natural selection.</em></u>
Explanation:
Natural selection is a type of selection in which those organisms are favoured to live and reproduce which are better adapted to live in an environment. Due to natural selection, the allele frequencies of a population will tend to change with the passage of time.
When the outbreak of malaria occurs, those organisms which do not catch malaria are able to survive and pass on their characteristics to their offsprings. the other organisms die and do not reproduce. This will cause changes in the allele frequencies.
You see, passive transport needs no energy. So that being said, it moves from areas with high concentration to areas with low concentration.

The role of DNA in all cells is to produce molecules of RNA that are involved in protein synthesis. Through the proteins, all the metabolism of the cell is controlled. DNA is also used to synthesize new DNA for daughter cells.
More than one third of North American bird species can be found in wetlands. Wetlands may contains fresh or salt water or both. Biodiversity and nutrient levels are high; many plants and organisms filter out waste materials. Birds like geese, ducks, herons, warbies, and egrets, to name a few, use wetlands for nesting and feeding.
