A salamander is cold blooded because it is a reptile.
Take a picture of the problem. It’d be much more helpful. Sounds like a heat transfer course. I am not sure whether it is external flow over a plate surface or just natural convection is occurring. You should have some equation listed in your book dT/dy. You need to integrate that equation with respect to y to find your temperature distribution as a function of y or x or in whichever direction you are considering. The 220°C sounds like a boundary condition where T(0)=220°C. Not entirely sure what else I could give you since there is not much to go off of. Thought I’d try.
One, a lot of mass extinctions are based on theories by scientist. Two, they all caused major changes in the Earth's systems (Ex. ecology, atmosphere, surface, and waters). Three, they all have theories on what caused it.
Also this is obvious but in all mass extinctions they wiped out a lot of lifeforms, 90% of anything that has EVER lived on the Earth is extinct.
Hope this helps! :-)
Answer:
This is important for laboratory safety.
Explanation:
It is important to read the Material Safety Data Sheet because it will inform you on what is being used in the lab and what to do/what not to do when chemicals or any materials are being involved.
