In what ways is the evolution of a massive
star similar to the evolution of the sun,
and in what ways is it different?

Similarity: Use the same formation to start evolution (carbon/oxygen core)

Difference: Bigger stars fuse slower than the sun because of the helium (stars are more gradual)

Hope this helped!

examples of nucleic acids are deoxyribonucleic acid (dna) and ribonucleic acid (rna).

radon is correct hope this
