Answer:
your answer is C polymerase Chain Reaction PCR
Answer;
The amount of water and the temperature of the water and the angle the bottle was set in.
Explanation;
The two main variables in an experiment are the independent and dependent variable;
-An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment.
The dependent variable is 'dependent' on the independent variable. As the experimenter changes the independent variable, the effect on the dependent variable is observed and recorded.
For example; the dependent variable in tornado in a bottle is the amount of water and the temperature of the water and the angle the bottle was set in.
You can put wind energy propellers on the front of your car. This would be effective, as the high speed of the car would increase the rate of energy produced.
You could also have a metal rod slightly scraping the ground, and take the heat generated by friction to produce energy.
Hope this helps!
