The answer is definitely B
According to Darwin's Theory of Natural Selection, each generation produces more individuals than the ecosystem can sustain. However, not all individuals are identical and phenotypical variation exists.
Due to this variation, some antelopes are better at escaping lions, perhaps due to speed and/or stamina. Thus, the individuals that are slower and thus less fit will be killed and eliminated from the herd. The antelopes with heritable traits that makes them better suited to the environment, will escape and thus, survive and reproduce.
In Darwin's Theory predation is an evolutionary force.
Answer:
Explanation:
Dependent variable is the outcome that is measured. This is the number of colonies produces by the clinical Isolate strain. Without the growth media the strain cannot thrive or reproduce hence their dependent on the media for survival.
While independent variable is the treatment that is varied in an experiment. It usually not dependent on any variable and can stand on it own.
The growth media that is lacking in chemical is the independent variable because it stands on it own and it can be carried depending on the experimental design it could be a chemical based growth media or no chemical like the one used in this experiment.
