The main difference between sexual and asexual reproduction is whether it has one or two parents. Sexual reproduction involves two parents and asexual involves one.
Another is that a large number of progenies are produced with asexual reproduction but a limited number of progenies are produced with sexual.
Like DNA, RNA is made up of nucleotides. There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.
The difference between them is that an ecosystem is a community of organisms and their environment. And a biosphere is all the living organisms.
