Convergent Evolution: In evolutionary biology, convergent evolution is the process whereby organisms not closely related (not monophyletic), independently evolve similar traits as a result of having to adapt to similar environments or ecological niches

81. Co-Evolution: "the influence of closely associated species on each other in their evolution".

81.1. Evidence of evolution: Fossils of living things that are no longer around and the absence of modern organisms from the fossil record has always been the most solid evidence of macro-evolution.

81.1.1. Embryonic similarities: Many traits of one type of animal appear in the embryo of another type of anima Fossil records: "A fossil record is a group of fossils which has been analyzed and arranged chronologically and in taxonomic order." Homologous / Vestigial structures: is the existence of shared ancestry between a pair of structures, or genes, in different species

82. Pathogens: a bacterium, virus, or other microorganism that can cause disease

82.1. Skin: The skin is the outermost protective covering of an organism.

82.1.1. Mucus and Cilia: "The mucus traps smaller particles like pollen or smoke. Hairlike structures called cilia line the mucous membrane and move the particles trapped in the mucus out of the nose. Inhaled air is moistened, warmed, and cleansed by the tissue that lines the nasal cavity." Saliva: watery liquid secreted into the mouth by glands, providing lubrication for chewing and swallowing, and aiding digestion. Stomach Acid: has a nifty way of digesting proteins and it's called stomach acid, though you might know it as gastric juice or simply acid.

83. Fevers: "is a body temperature that's higher than is considered normal. It's also called a high temperature, hyperthermia, or pyrexia, and it's usually a sign that your body is working to keep you healthy from an infection"

83.1. Antigens: "a toxin or other foreign substance which induces an immune response in the body, especially the production of antibodies"

83.1.1. Antibodies: "a blood protein produced in response to and counteracting a specific antigen. Antibodies combine chemically with substances which the body recognizes as alien, such as bacteria, viruses, and foreign substances in the blood" Helper Cells: "a T cell that influences or controls the differentiation or activity of other cells of the immune system" Plasma B Cells: "hite blood cells that originate in the bone marrow and secrete large quantities of proteins called antibodies in response to being presented specific substances called antigens".

83.2. Active Immunity:is defined as immunity to a pathogen that occurs following exposure to said pathogen

83.2.1. Passive Immunity:the short-term immunity which results from the introduction of antibodies from another person or animal Antibiotics: are medicines that fight bacterial infections in people and animals. They work by killing the bacteria or by making it hard for the bacteria to grow and multiply Antivirals:an antiviral drug or medicine
