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.

Explanation:

It is possible to determine whether a sample of muscle tissue moved the skeleton, the heart, or another type of internal organ by analyzing its cellular structure and organization. For instance cardiac muscle is striated and organized into sarcomeres, while smooth muscle that is located in organs such as intestines, uterus and stomach are not organized into sarcomeres.
