Pick an answer in your head, then open the explanation.

  1. 1. Which chamber of the heart pumps oxygen-rich blood out to the body?

    • A. Right atrium
    • B. Right ventricle
    • C. Left atrium
    • D. Left ventricle
    Show answer & explanation

    Answer: D. Left ventricle

    The left ventricle pumps oxygenated blood into the aorta and out to the body.

  2. 2. Where in the cell does most ATP production happen?

    • A. Nucleus
    • B. Ribosome
    • C. Mitochondria
    • D. Golgi apparatus
    Show answer & explanation

    Answer: C. Mitochondria

    Mitochondria carry out cellular respiration, which makes most of the cell's ATP.

  3. 3. A solution has a pH of 3. It is:

    • A. Strongly basic
    • B. Neutral
    • C. Acidic
    • D. Slightly basic
    Show answer & explanation

    Answer: C. Acidic

    pH below 7 is acidic; 7 is neutral; above 7 is basic.

  4. 4. A student tests how different amounts of light affect plant growth. What is the independent variable?

    • A. Plant height
    • B. Amount of light
    • C. Type of soil
    • D. Amount of water
    Show answer & explanation

    Answer: B. Amount of light

    The independent variable is what the experimenter changes on purpose — the amount of light.

Study tips

  • Learn each body system's main job and organs before memorizing small details.
  • Know the parts of an experiment: independent variable, dependent variable and control.
  • Review basic chemistry: atoms, bonds, pH and balancing simple equations.
