Prokaryotes divide by binary fission, a form of asexual reproduction in which a cell divides into two cells with identical genetic information.

Explanation:

Binary fission and mitosis can be viewed as the same principle of  asexual reproduction to give out two identical cells. However, the major difference between the two is that binary fission is to prokaryotes and mitosis is to eukaryotes. Remember that prokaryotes do not have a true nucleus (they have a nucleoid) hence binary fission does not involve the dividing of the nucleus. Mitosis does.

Sexual reproduction is responsible for creating variation in offspring especially due to the process of meiosis in gamete development and subsequent fertilization of two gametes from different parents.

A scientist finds two similar flies that have the same size, coloration, and overall morphology. However, further studies show t
hram777 [196]
The answer is <span>B.) Both flies belong to the same genus but different species.

Species is a group of similar organisms able to reproduce (to exchange genes and interbreed) only within the group. That means that organisms from different species could not exchange genes. So, if two similar flies are no able to mate, it can be concluded that they are not the same species. Still, they are similar enough to belong to the same genus, but different species.</span>
