How does my body know to wake up when morning comes? let me know the answer

Your alarm you hear your alarm. And that wakes you up your brain is the puppeteer of your body the control center you your brain is always on. When you hear the alarm your brain wakes up the body.

Hello Sno76712,
 
it doesn't necessarily wake up because it's morning. it wakes up when it has had enough sleep, if you were to go to bed at 3 pm it would most likely wake its self up when it feels it has been well rested. so it all really depends on what time you go to bed and your sleeping habits, also it can also have to do with the alarm you have. it you are set to wake up at 6 am every morning your body will naturally start to wake up around that time, same as it would happen as your going to bed!

hope that makes sense :D

When a virus infects a host cell, it uses the cell's machinery to make copies of its own genetic material in a process called replication. finally, during the process of self-assembly, that protein shell and the copies of the virus's genetic material are assembled into new viruses.
