Which of the following can evolve: an individual, an organism, habitats, populations. In evolutionary biology, adaptation is best defined as: reversible adjustment by an individual, evolved traits that enhance an organism"s survival or reproduction, genetic variation, neutral mutation. The car won"t start: observation, in turn, leads to a question. Why won"t the car start: after referring to prior research, thinking, recalling prior experience, and/or conferring with colleagues, a hypothesis an informed explanation is formed. The battery may be dead: a prediction, based on the hypothesis, is made. If the battery is dead, then a jump-start should start the car: the prediction is tested in an experiment. Attach jumper cables: a conclusion refutes or supports the hypothesis. If the car starts, the hypothesis is supported: biologists test hypotheses using controlled experiments, two types of situations are established, control, baseline, all possible variables are held at a constant, experimental.
