Which of the following best explains the value of these competing theories? 1 Competing theories can be a source of new, testable ideas. 2Competing theories are necessary to transform a theory into a law. 3Competing theories generate controversy that helps popularize ideas. 4Competing theories allow scientists to combine the most interesting aspects of both theories.

yeah the answer is mean

well, their are quite a few differences !

explanation:

first difference is a main sequence star is made of carbon, while a neutron star is made of neutrons. another difference is a main sequence star still has hydrogen to burn, while a neutron star is a remnant of a supernova.

a main sequence star is what’s left over from a low-mass star death, while a neutron star is what’s left from the death of a high-mass star. main sequence star and a neutron star are considered the same thing, except a main sequence star spins.
