  1. 1. The finches of the Galapagos Islands have different shaped beaks to feed on different food sources. What is this an example of?

    Charles J Sharp / en.wikipedia.org / BuzzFeed
    Correct
    Incorrect
    Anatomical adaptation
    Correct
    Incorrect
    Behavioural adaptation
    Correct
    Incorrect
    Physiological adaptation
    Correct
    Incorrect
    Selective adaptation
    Correct!
    Wrong!

    It's an anatomical adaptation because it relates to the birds' shape.

  2. 2. Complete the following statement:

    Kelly Oakes / BuzzFeed
    Correct
    Incorrect
    ...contain ribose.
    Correct
    Incorrect
    ...contain thymine.
    Correct
    Incorrect
    ...have a double helix structure.
    Correct
    Incorrect
    ...have a sugar-phosphate chain.
    Correct!
    Wrong!

    A sugar-phosphate chain forms the backbone of both DNA and RNA. The sugar in DNA is deoxyribose, whereas in RNA it's ribose.

  3. 3. Complete the following statement:

    Kelly Oakes / BuzzFeed
    Correct
    Incorrect
    ...diploid cells can inherit DNA from both parents.
    Correct
    Incorrect
    ...hydrolysis of DNA is faster.
    Correct
    Incorrect
    ...semi-conservative replication is possible.
    Correct
    Incorrect
    ...transcription and replication can occur at the same time.
    Correct!
    Wrong!

    Semi-conservative replication creates two copies, each of which contains one of the original strands.

  4. 4. What's the maximum number of amino acids coded for by a molecule of mRNA that is 600 mononucleotides long?

    Correct
    Incorrect
    100
    Correct
    Incorrect
    200
    Correct
    Incorrect
    300
    Correct
    Incorrect
    600
    Correct!
    Wrong!

    Three nucleotides makes one codon, and each codon codes for one amino acid.

  5. 5. Plant and animal cells may both contain:

    Correct
    Incorrect
    amyloplasts, centrioles and mitochondria
    Correct
    Incorrect
    mitochondria, rough endoplasmic reticulum and smooth endoplasmic reticulum
    Correct!
    Wrong!

    Amyloplasts are only found in some plant cells.

  6. 6. Which are the two domains that contain prokaryotic cells?

    Correct
    Incorrect
    Animalia and Bacteria
    Correct
    Incorrect
    Archaea and Bacteria
    Correct
    Incorrect
    Bacteria and Plantae
    Correct!
    Wrong!

    A prokaryote is a single-celled organism that doesn't have a nucleus with a membrane or mitochondria.

  7. 7. What words fill in the three blanks in this sentence?

    Kelly Oakes / BuzzFeed
    Correct
    Incorrect
    unspecialised / any / including
    Correct
    Incorrect
    unspecialised / almost any / excluding
    Correct
    Incorrect
    specialised / almost any / including
    Correct
    Incorrect
    specialised / any / excluding
    Correct!
    Wrong!

    Pluripotent stem cells can differentiate into almost any specialised cell in the body, but totipotent cells are more versatile and can differentiate into any cell in the body.

  8. 8. What could join two of these molecules together?

    Kelly Oakes / BuzzFeed
    Correct
    Incorrect
    a hydrogen bond
    Correct
    Incorrect
    an ionic bond
    Correct
    Incorrect
    a peptide bond
    Correct!
    Wrong!

    It's a water molecule. Water molecules form hydrogen bonds with each other.

  9. 9. What's the name of the fibrous protein in the skin that forms a barrier and stops microorganisms getting in?

    Correct
    Incorrect
    cytokine
    Correct
    Incorrect
    interferon
    Correct
    Incorrect
    keratin
    Correct
    Incorrect
    lysozome
    Correct!
    Wrong!

    Keratin protects epithelial cells from damage.

  10. 10. You decide to ride a bicycle uphill. Which part of your brain is associated with making the decision?

    Correct
    Incorrect
    cerebrum
    Correct
    Incorrect
    cerebellum
    Correct
    Incorrect
    hypothalamus
    Correct
    Incorrect
    medulla
    Correct!
    Wrong!

    The cerebrum is responsible for starting and coordinating your body's voluntary activity, among other things.

  11. 11. As you ride the bike uphill you start sweating. Which part of your brain initiates the increase in sweating?

    Correct
    Incorrect
    cerebrum
    Correct
    Incorrect
    cerebellum
    Correct
    Incorrect
    hypothalamus
    Correct
    Incorrect
    medulla
    Correct!
    Wrong!

    The hypothalamus controls your body temperature. As you start to get too hot while cycling, it triggers your sweat glands to cool you down.

  12. 12. What units should appear on the y-axis of this graph?

    Edexcel / qualifications.pearson.com / BuzzFeed
    Correct
    Incorrect
    kg
    Correct
    Incorrect
    kJ m⁻¹

    kJ m⁻² year⁻¹
    Correct
    Incorrect
    kg m⁻¹ year⁻¹
    Correct!
    Wrong!

    Net primary productivity (NPP) is defined as the net flux of carbon from the atmosphere into green plants per unit time.
