Questions and Answers

Why is simply copying DNA in a dividing cell not enough to maintain continuity of life?

  • Simply copying DNA causes cellular damage
  • Copying DNA does not ensure genetic variation
  • Copying DNA leads to overpopulation
  • An organized cellular structure is required to maintain life processes (correct)

    • What is the significance of reproduction for the maintenance of continuity of a species?

  • Replacement of individuals as they age (correct)
  • Enhancement of individual traits
  • Prevention of genetic mutations
  • Increase in individual lifespan

    • Why is variation beneficial to the species but not necessary for the individual?

  • Variation causes genetic disorders in individuals
  • Variation makes species more adapted to survive changing conditions (correct)
  • Variation leads to shorter individual lifespans
  • Variation increases individual competition
