Answer:
Abiotic factors are the non-living factors that support the life on earth. The make up the environment suitable for the survival and growth of the living species like soil, water, sunlight and others. Biotic factors are the living species like plants, animals, microbes and humans.
A cow is a herbivores animals, that utilizes grasses,shrubs and leaves as food, it also need water to drink and oxygen to breath and respire. Therefore, the two example of abiotic factors which a cow will experience in it's environment is oxygen and water and biotic factors will be grasses and another member of the same species as mate, to undergo copulation and produce a new offspring.
The immune system protects the body from possibly harmful substances by recognizing and responding to antigens. Antigens are substances (usually proteins) on the surface of cells, viruses, fungi, or bacteria. Nonliving substances such as toxins, chemicals, drugs, and foreign particles (such as a splinter) can also be antigens. The immune system recognizes and destroys, or tries to destroy, substances that contain antigens. Your body's cells have proteins that are antigens. These include a group of antigens called HLA antigens. Your immune system learns to see these antigens as normal and usually does not react against them.
Innate, or nonspecific, immunity is the defense system with which you were born. It protects you against all antigens. Innate immunity involves barriers that keep harmful materials from entering your body. These barriers form the first line of defense in the immune response. Examples of innate immunity include:
Cough reflex
Enzymes in tears and skin oils
Mucus, which traps bacteria and small particles
Skin
Stomach acid
Innate immunity also comes in a protein chemical form, called innate humoral immunity. Examples include the body's complement system and substances called interferon and interleukin-1 (which causes fever). If an antigen gets past these barriers, it is attacked and destroyed by other parts of the immune system. Acquired immunity is immunity that develops with exposure to various antigens. Your immune system builds a defense against that specific antigen. Passive immunity is due to antibodies that are produced in a body other than your own. Infants have passive immunity because they are born with antibodies that are transferred through the placenta from their mother. These antibodies disappear between ages 6 and 12 months. Passive immunization may also be due to injection of antiserum, which contains antibodies that are formed by another person or animal. It provides immediate protection against an antigen, but does not provide long-lasting protection. Immune serum globulin (given for hepatitis exposure) and tetanus antitoxin are examples of passive immunization.
