• The adaptation of an organism to its external environment for survival

• The ability of an organism to reproduce and pass on its genetic material to offspring.

• Conditions are regulated to maintain a stable and balanced internal environment.

In a scientific experiment, which is the key distinction between the independent variable and the dependent variable?

• The dependent variable is manipulated by the experimenter, while the independent variable is the observed outcome.

• Both the dependent and independent variables are manipulated at the same time.

• The independent variable is the experimental group and the dependent variable is the control group.

Which of the following is a proper way to write a scientific hypothesis?

• Watering plants may or may not affect their growth speed because energy is not dependent on water.

• I believe that if I water my plants everyday, then they will grow faster because they can create more energy.

• If water is applied everyday to my plants, then they will grow faster because they can create more energy.

• My hypothesis is that watering plants every day will make them have more energy and grow faster.
