    Food contains chemical potential energy stored in molecular bonds, which cells release through cellular respiration.

  3. Two forces of 10 N and 6 N act in the same direction on an object. What is the net force?

    Answer: 16 N

    When forces act in the same direction, they add together: 10 N + 6 N = 16 N.

  4. Which gas makes up the largest percentage of Earth's atmosphere?

    Answer: Nitrogen

    Nitrogen (N₂) comprises approximately 78% of Earth's atmosphere, far more than oxygen at about 21%.

  5. A scientist repeats an experiment five times and gets similar results each time. This best demonstrates which scientific principle?

    Answer: Reproducibility

    Reproducibility means an experiment yields consistent results when repeated, strengthening confidence in the findings.

  6. Which process do plants use to make their own food using sunlight?

    Answer: Photosynthesis

    Photosynthesis converts light energy, water, and CO₂ into glucose and oxygen in chloroplasts.

  7. What is the term for a change in the DNA sequence of an organism?
