Well the spread of diseases is caused by bacteria.These one-cell organisms are responsible for illnesses such as strep throat urinary tract infections and tuberculosis.Viruses even smarter than bacteria viruses cause a multitude of diseases from the common cold to aids like fungi and parasites.
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.

An area where soil has eroded experience loss of nutrients. The topmost layer of soil is called the topsoil and is the most fertile. Soil erosion results in the loss of soil fertility and makes the land barren
The main cause of soil erosion is the removal of vegetation, which exposes the topsoil to water and wind. Wind and water are the main agents of soil erosion.
Water erosion can be sheet erosion, rill erosion, gully erosion or riparian erosion.
