Questions and Answers

Which of the following best describes homeostasis?

  • The tendency to amplify changes and move away from the starting state
  • The tendency to fluctuate between different internal environments
  • The tendency to adapt to external changes
  • The tendency to resist change and maintain a stable internal environment (correct)

How do positive feedback loops differ from negative feedback loops?

  • Positive feedback loops amplify their initiating stimuli, moving the system away from its starting state (correct)
  • Positive feedback loops counteract changes and maintain the target values
  • Positive feedback loops adapt to external changes
  • Positive feedback loops fluctuate between different internal environments

What is the role of negative feedback loops in homeostasis?

  • To amplify changes and move away from the starting state
  • To fluctuate between different internal environments
  • To adapt to external changes
  • To counteract changes and maintain the target values (correct)
