A group of lions of a single species that live in the same general area of a prairie at the same time will be the best example of population.
A perfect population means a group of single species that can interbreed and can live at the same time in the same environment. Although if a group of lions of single species that live in the same general area of prairie can interbreed more easily and can perfectly increase their generations at the same time.

Answer:
Hypothesis: If there is a rat, THEN an elephant will react differently
Independent variable: Presence or absence of rat
Dependent variable: Elephant's reaction
Conclusion: The hypothesis is accepted because rats make an elephant to react.
Explanation:
A hypothesis is a predictive statement about a particular observation made, which is what we're doing next. In this case, a possible statement that suggests solution could be: If there is a rat, THEN an elephant will react differently.
Independent variable is the variable being manipulated in an experiment. The PRESENCE OR ABSENCE OF RATS is the independent variable
Dependent variable is the variable that the experimenter measures. In this experiment, the measurable variable/dependent is the ELEPHANT'S REACTION.
Conclusion of an experiment either rejects or accepts the hypothesis depending on the outcome of the experiment. In this, let it be assumed that the conclusion has been accepted
