Questions and Answers

What are the three main components of a cell?

  • Cytoplasm, cell membrane, and ribosomes
  • Nucleus, cytoplasm, and cell membrane (correct)
  • Nucleolus, lysosomes, and Golgi apparatus
  • Nucleus, mitochondria, and ribosomes

What is the purpose of cellular responses to stress and noxious stimuli?

  • To cause cell death
  • To trigger an immune response
  • To initiate mitosis
  • To protect the cell and maintain homeostasis (correct)

What happens to a cell when it is exposed to noxious stimuli?

  • It may experience injury, but not necessarily death (correct)
  • It becomes immune to stress
  • It undergoes mitosis
  • It immediately dies
