What is a positive way to look at the melting glaciers and subsequent rising shorelines ?
a) we have plenty of warning
b) we do great things when challenged and focused
c) we need to spread the word
d) all of the above

I would say D.) All of the above 
hope that helps!!

I believe the answer is D because they are all true i just don't know if there was a specific answer. I believe it's really opinionated.

The proton has a positive charge while the neutron has no charge they both make up the nucleus of the atom while the elections have a negative charge and surround the nucleus of the atom. the protons and electrons are used to calculate the atom's mass whereas the neutrons don't affect the mass
