Question

question 1 (1 point)
the ____________ controls our biological clock.
○ hippocampus
○ thalamus
○ hypothalamus
○ pituitary gland

Explanation:

To solve this, we analyze each option:

• Hippocampus: Involved in memory formation, not biological clock.
• Thalamus: Relays sensory information, not biological clock control.
• Hypothalamus: Contains the suprachiasmatic nucleus (SCN) which regulates the biological clock (circadian rhythms).
• Pituitary gland: Regulates hormones but not the biological clock directly.

Answer:

C. hypothalamus
