B went on strike because it’s the only answer that looks true
Hello, the answer to your question is Jim Gallien
Answer:
Circadian rhythm, or circadian clock, is an internal biological clock that regulates sleeping and feeding patterns, as well as a whole host of other biological functions in all living organisms. Organisms most active in the daytime are diurnal, humans included, whereas nocturnal organisms come alive at night.
Think of it like this
Internal: A force inside yourself
External: A force outside of yourself
So if there an external force, it’s a force from outside so an example would be bullying. You wouldn’t want to go where you are being bullied so that would be an outside force affecting you.
