Questions and Answers

What is the purpose of artificial selection?

  • To decrease genetic variation in a population
  • To cause species to experience random changes
  • To prevent species from adapting themselves
  • To push populations toward favorable trait combinations (correct)

    • Which process explicitly does not make a population better adapted to the environment?

  • Genetic drift
  • Selective pressures (correct)
  • Mutation
  • Gene flow

    • What is the role of genetic drift in changing the genetic profile of a population?

  • Brings new variants of traits into populations
  • Changes the genetic profile due to random deaths (correct)
  • Creates new variations in the population
  • Selects more variants over others based on selective pressure

    What is an example of a positive feedback loop in the context of global warming?

    <p>The warming of the atmosphere increases evaporation and cloud cover, leading to more heat being trapped.</p> Signup and view all the answers
