  3. Question 3

    A bacterium divides into two every 60 minutes. Starting with one cell, how many cells are there after 5 hours (if none die)?

    Answer

  4. Question 4

    What is an advantage of sexual reproduction?

    • A. It is faster than asexual reproduction

  5. Question 5

    Mitosis or meiosis? It keeps the full number of chromosomes (46 in humans).

    • A. mitosis
    • B. meiosis

    Answer

  7. Question 7

    Which type of reproduction produces offspring that are genetic clones of the parent?

    • A. meiosis
    • B. asexual reproduction

  8. Question 8

    Mitosis or meiosis? It keeps the full number of chromosomes (46 in humans).

    • A. mitosis

  9. Question 9

    A bacterium divides into two every 30 minutes. Starting with one cell, how many cells are there after 2 hours (if none die)?

    Answer

  10. Question 10

    Why must gametes have half the normal number of chromosomes?

    • A. So the fertilised egg has the full number again
    • B. Because they are smaller
    • C. So they can swim faster
    • D. So the baby has no chromosomes
