• Correct Answer: Protein synthesis
Question 9
A tendency for organisms to maintain a balanced or constant internal
state is called:
• Correct Answer: Homeostasis
Question 10
Explain how negative feedback maintains homeostasis.
• Correct Answer: Negative feedback works by detecting
changes in a physiological variable and initiating responses that
counteract the deviation from the normal range (e.g., body
temperature regulation).

A feedback loop in which a system responds to a change by amplifying
that change (Ex. childbirth) is a:
• Correct Answer: Positive Feedback Loop
, Question 12
Changes, occurring within or outside the body, that affect homeostasis
are known as:
• Correct Answer: Stimuli
Question 13
The detects and sends messages to the control center.
• Correct Answer: Receptor

Question 15
What role do mitochondria play in the cell?
• They form vesicles that transport proteins and lipids.
• They are involved in packaging and shipping cellular materials.
• They produce digestive enzymes to break down
biomacromolecules.
• Correct Answer: They convert chemical energy from food into
ATP through aerobic cellular respiration.
Question 16
Which organelle is primarily responsible for energy production (ATP) in
the cell?
