Natural selection occur to give the best survival chance to the organisms. Hence, they bring about biological evolution through future generations thereby increasing the variety of living things. This survival reflects on their ability to produce more offspring. The offspring must continue to survive by competing with the resources found in nature.

Answer:
Viruses and prions are considered microbes.
Some microbes are visible to the naked eye.
Explanation:
Microbes are the tiny organisms that can not be seen with unaided eyes. However, this does not hold true for all and some microbes like <em>Epulopiscium fishelsoni</em> can be seen with unaided eyes. Bacteria, viruses, protozoans, and prions are some of the microbes. Viruses are the microbes that have a protein coat around their genetic material. Prions are proteins that can cause infections. Prions do not have any genetic material.
<span> Amoebic dysentery is caused by the amoeba Entamoeba histolytica. This protozoan exists in nature in the cyst form and is transmitted by contaminated food and water. In patients, the amoebas revert to trophozoites and invade the intestinal lining.
Your answer is C.
