Genetics is the study of heredity or inheritance. Genetics helps to explain how traits are passed from parents to their young. Parents pass traits to their young through gene transmission (for example hair and eye color, shape of ears, cheek bones, and mouth shape). Genes are located on chromosomes and consist of DNA (A chromosome is a long, stringy aggregate of genes that carries heredity information (DNA) and is formed from condensed chromatin). They contain specific

Special cells called "mast cells" also line the inside of the nose, throat, lungs and skin. Bacteria or viruses that want to gain entry to the body must first make it past these defenses. Once inside a body, a germ deals with a different level of the immune system. The major components of the immune system are: The thymus, spleen, lymph system, bone marrow, white blood cells, antibodies, complement system, and hormones. But there’s another part of the immune system which isn’t usually concluded upon. Except in this case it is what helps break down the chemicals in medications that allow the drug become active in our system, this ensures that the drug take some effect on your body. This is known as hydrogen peroxide. Hydrogen peroxide is widely regarded as a cytotoxic agent whose levels must be minimized by the action of antioxidant defense enzymes. The level of hydrogen peroxide in your body can be raised by certain things you drink throughout the day. Especially things like instant coffee. Everyone has different amounts of H2O2 (Hydrogen Peroxide) in their bodies, this variation of the chemical balance in their bodies is one of the causes of why the same dosage of a medication can possibly affect people differently.
