To determine the correct answer, we need to understand what abnormal cell division and its consequences are. When cells divide abnormally, it means that there is an error or mutation in the cell's genetic material, such as its DNA. This mutation can disrupt the normal process of cell division, leading to various health issues.
Out of the given options, let's evaluate which one is caused by abnormal cell division:
1. Sickle cell anemia: Sickle cell anemia is a genetic disorder caused by a mutation in the hemoglobin gene, which is responsible for the shape and function of red blood cells. This mutation results in the production of abnormal hemoglobin, leading to the sickling of red blood cells. However, sickle cell anemia is not directly caused by abnormal cell division but rather by a specific genetic mutation affecting the hemoglobin gene. So, this option is not the correct answer.
2. Cystic fibrosis: Cystic fibrosis is a genetic disorder caused by a mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. This mutation affects the production and function of a specific protein involved in the transport of chloride ions in the body. The abnormal CFTR protein disrupts the normal salt balance across cell membranes, leading to the production of thick, sticky mucus in various organs. Similar to sickle cell anemia, cystic fibrosis is caused by a specific genetic mutation rather than abnormal cell division. Therefore, this option is not the correct answer.
3. Skin cancer: Skin cancer is a broad term encompassing different types of cancers that originate in the skin. While UV radiation from the sun is the primary risk factor for developing skin cancer, it can also be caused by several genetic mutations. Some of these mutations affect genes involved in the regulation of cell growth and division, leading to abnormal cell division in the skin. Hence, abnormal cell division is a contributing factor to the development of skin cancer. This option is a correct answer.
4. Clogged arteries: Clogged arteries, also known as atherosclerosis, result from the buildup of plaque inside the arteries, causing them to narrow and restrict blood flow. Although plaque buildup can be caused by various factors such as high cholesterol, inflammation, and lifestyle choices, it is not directly related to abnormal cell division. Thus, this option is not the correct answer.
Therefore, the correct answer is skin cancer, as it can be caused by mutations that affect the regulation of cell growth and division in the skin.
