1) If a person has neither of the two blood antigens, their blood type is O. To understand why, you need to know that blood can be categorized into different types based on the presence or absence of certain antigens. Antigens are substances that can trigger an immune response in the body. The two main antigens related to blood typing are A and B antigens. When someone has neither A nor B antigen on their red blood cells, their blood type is considered O.
4) Testosterone is produced in the testes. To determine this, you need to know that testosterone is a male sex hormone responsible for various functions such as the development of male reproductive organs and secondary sexual characteristics. The testes are the primary source of testosterone production in males.
6) The type of cell capable of digesting and engulfing dangerous particles or cells harmful to the body is a phagocyte. To arrive at this answer, you need to understand that phagocytes are a type of white blood cell involved in the body's immune response. They specialize in engulfing and digesting harmful pathogens, such as bacteria or dead cells.
7) The thickening and hardening of the artery wall is called arteriosclerosis. To determine this, you need to understand that arteriosclerosis is a condition characterized by the buildup of fatty plaques and calcium deposits on the inner walls of arteries, leading to their narrowing and hardening. This condition can restrict blood flow and increase the risk of various cardiovascular diseases, such as heart attack or stroke.
