  1. 1.

    It's made up of glands that produce and secrete hormones.
    It's made up of nerve cells that transmit electrical signals around the body.
    Correct!
    Wrong!

    It secretes hormones.

    The endocrine system includes your pancreas, adrenal gland, and ovaries or testes.

  2. 2.

    6.022 x 10^23
    6.023 x 10^22
    Correct!
    Wrong!

    6.022 x 10^23

    It's known as the Avogadro number.

  3. 3.

    A vector only has magnitude, a scalar has magnitude and direction.
    A scalar only has magnitude, a vector has magnitude and direction.
    Correct!
    Wrong!

    A vector has both magnitude and direction.

    For example, speed is a scalar, but velocity is a vector.

  4. 4.

    Excess nutrients from fertilisers get into water and encourage plant growth.
    Algae blooms on the surface of the water.
    Sunlight can't get through the algae to underwater plants, so they die.
    There is excess oxygen in the water because of the decaying plants.
    Correct!
    Wrong!

    Eutrophication is when nutrients cause algal growth.

    The bloom blocks sunlight from getting to the underwater plants, so they die, and oxygen in the lake is depleted, eventually causing fish and other life to die.

  5. 5.

    Because hydrogen bonding means the molecules are arranged further apart as ice than when they are liquid.
    Because hydrogen bonding means the molecules are arranged closer together as ice than when they are liquid.
    Correct!
    Wrong!

    They're further apart.

  6. 6.

    "In an electrical circuit, the total current that enters a junction is equal to the total current that leaves the junction."
    "In an electrical circuit, the current is directly proportional to the voltage and inversely proportional to the resistance."
    Correct!
    Wrong!

    Kirchoff's laws are about conservation in a circuit.

  7. 7.

    A substrate being the right pH
    Their complementary shapes
    Correct!
    Wrong!

    Complementary shapes

    In the lock and key model, the substrate and enzyme fit together.

  8. 8.

    Testosterone
    Follicle-stimulating hormone (FSH)
    Correct!
    Wrong!

    Follicle-stimulating hormone (FSH)

    Gonadotrophin are a group of hormones secreted by the pituitary gland which stimulate the activity of the testes and ovaries.

  9. 9.

    Alkali metals
    Noble gases
    Transition metals
    Correct!
    Wrong!

    Noble gases

    The last column of the periodic table contains the noble gases, including helium, neon, argon, etc.

  10. 10.

    Up
    Charm
    Bottom
    Weird
    Correct!
    Wrong!

    "Weird" is not a type of quark.

    There are six actual quarks in total: up, down, strange, charm, top and bottom.
