Which disease can vitamin B12 deficiency be attributed to?
Diabetes
Obesity
Alcoholism
Hypertension
The Correct Answer is C
Vitamin B12 is a water-soluble vitamin that is involved in the production of red blood cells, DNA synthesis, and nerve function. Vitamin B12 deficiency can cause anemia, neurological problems, and cognitive impairment. Vitamin B12 deficiency can be attributed to alcoholism because alcohol interferes with the absorption and metabolism of vitamin B12 in the stomach and liver. Alcohol also damages the lining of the intestines, where vitamin B12 is absorbed from food sources.

Marfan syndrome is a genetic disorder that affects the connective tissue, causing problems with the heart, blood vessels, eyes, bones, and joints. It is caused by a mutation in the FBN1 gene, which encodes for a protein called fibrillin-1. Marfan syndrome follows an autosomal dominant pattern of inheritance, which means that only one copy of the mutated gene is needed to cause the disorder. A person with Marfan syndrome has a 50% chance of passing on the mutated gene to each child, regardless of the gender of the parent or the child.

HIV stands for human immunodeficiency virus, a virus that infects and destroys CD4+ T cells, which are a type of white blood cell that coordinates the immune response against foreign invaders. HIV can cause acquired immunodeficiency syndrome (AIDS), which is a condition where the immune system becomes severely weakened and unable to fight off common infections and cancers. HIV can be transmitted through sexual contact, blood transfusion, needle sharing, or mother-to-child transmission.
