6. What's the nucleolus?

  • inside the nucleus and manufactures ribosomes
  • synthesises proteins
  • organise the nuclear spindle during cell division
  • produce energy in the form of ATP

7. What describes a hypotonic solution?

  • have a really low concentration than the concentration inside a given cell/tissue/body compartment
  • low concentrations than the concentration inside a given cell/tissue/body compartment
  • have a higher concentration than the concentration inside the given cell/tissue/body compartment
  • have the same concentrations as the concentration inside a given cell/tissue/body compartment

8. What is thermoregulation?

  • maintain the correct body
  • maintain correct temperatures for bodily functions
  • to get rid of toxic substances
  • the sum of total chemical reactions taking place in the body

9. How does a substance pass using phagocytosis?

  • uptake of liquid into the cell by invagination of the cell
  • uptake of water into the cell by invagination of the cell membrane
  • uptake of solid material into the cell by invagination of the cell membrane
  • uptake of sodium into the cell by invagination of the cell membrane

10. What's the role of cytoplasm?

  • is required for cell respiration
  • part of the cell where everything is contained within

20. What happens if the cell's concentration is lower than its surroundings?

  • cell will burst
  • water will move out of the cell by osmosis and solutes will move into the cell by diffusion
