so today it's going to e boring because I had to do a review. so I thought about what to say. and I guess we can just review them like in the book. first, we will talk about carbon 14 if you might know this type of molecule takes a very long time to stabilize. like 7,000 years so scientists can use this to find the age of bone and things and you still might remember the polio epediemic. this disease worked very fast in maiming or killing people and a man named joseph salk made a vaccine for it and that is what you get today just about the same time.

so I have read this part before but I never told you about it this is quite interesting. called rooster earplugs the rooster lets out a cockle doodle do that has 140 decibels. of sound that's loud enough to defend. you that is why the rooster does it in a high place and away from the hens. so he doesn't deafen them also the rooster has these built-in earplugs that totally block up his ear ducts. also he has a lot of hair or something like that in there so it would have to get through that. see even in this stupid animal God has put in these amazing adaptions or something like that other than adaptions.
