Match the vocabulary term to its correct definiton:

Draggable emne		Korresponderende emne
Natural Selection		A gradual change in the heritable traits within a population over a long period of time.
Variation		Organisms who are better adapted to their environment tend to survive and reproduce more offspring than the organisms who are unfit.
Adaptation		The differences in the physical traits that exist between individuals within a population.
Evolution		An organism's ability to survive long enough to reproduce.
Fitness		Good traits that an organism has that helps it to survive and reproduce better in a particular environment.

Fitness is the ability of an organism to survive and and pass on its traits.

Salamanders in coastal California exhibit color variations based on their habitats; those in dark redwood forests are dark-colored, while those in light sandy soils, like at Fort Ord Natural Reserve, are pale pink.

A population of dark-colored salamanders is introduced to Fort Ord, where there are many predators, the population of the dark-colored salamanders will .

Which statement best describes how only a few resistant bacteria resulted in the antibiotic to stop working?

The resistant bacteria change the chemical make up of the antibiotic, rendering it ineffective.

The resistant bacteria grow larger and the antibiotic can no longer work on them

The bacteria that were resistant managed to survive and form a population that is likewise resistant.

The resistant bacteria attack the antibiotic rendering it ineffective
