Biological Clocks in Microgravity – Definition & Detailed Explanation – Astrobiology Glossary
I. What are biological clocks? Biological clocks, also known as circadian rhythms, are internal mechanisms that regulate various physiological processes in living organisms. These clocks are responsible for controlling the timing of sleep-wake cycles, hormone production, body temperature, and other essential functions. They are influenced by external cues such as light and temperature, but they … Read more
