Answer:
3. Only one independent variable is used for each experiment.
Explanation:
A controlled experiment is an experiment in which one variable is changed or tested at a time, while others are kept constant. In an experiment, one of the two major variables is INDEPENDENT VARIABLE. Independent variable is the variable that is changed or manipulated in the experiment.
In a controlled experiment, only one independent variable is used at a time i.e. ONLY one variable is changed or manipulated for each experiment. This is to ensure the validity of the experiment.
Answer;
Evolution
Mutations such as polyploidy and crossing over provide the genetic basis for evolution.
Explanation;
Evolution is the change in the characteristics or traits of a species over several generations and relies on the process of natural selection.
It occurs when some individuals or some alleles (alternative form of gene) reproduce themselves more than others,increasing their prevalence in subsequent generation.
Polypoidy and crossover brings about mutations that cause changes in characteristics and traits over time resulting to evolution.
