What is the main difference between dynamic and static equilibrium?
Static equilibrium involves constant changes; dynamic equilibrium does not.
Dynamic equilibrium involves balance through ongoing changes, while static equilibrium does not involve change.
Both terms mean the same thing.
Static equilibrium only occurs in living systems.
Which of the following is an example of the body maintaining homeostasis?
Sweating when it’s hot.
Holding your breath underwater.
Getting a sunburn.
Standing still.
What is a key difference between positive and negative feedback loops?
Positive feedback opposes change; negative feedback amplifies it.
Negative feedback opposes change; positive feedback amplifies it.
Both types stop the stimulus.
Only negative feedback occurs in living systems.
Which of the following is an example of a positive feedback loop?
Childbirth.
Regulation of blood sugar.
Sweating to cool down.
Shivering to warm up.
How does the cell membrane help maintain homeostasis?
By controlling the flow of substances in and out of the cell.
By breaking down harmful toxins.
By storing energy.
By creating new organelles.
