Natural immunity occurs through contact with a disease. There are two types of natural immunity. Actively acquired and passively acquired.
Actively acquired - When the body has already experience an infection by that pathogen
Passively acquired - Antibodies pass across placenta providing a newborn baby with immunity against disease. Antibodies are also present in breatsmilk.
Artificial immunity develops through delibereate action such as vaccine. There are two types: Actively acquired and passively acquired
Actively acquired - This is by vaccination at a suitable time in the person's life, not when they are infected. eg TB vaccine
Passively acquired - The vaccine contains ready-made antibodies which provide immediate relief by destroying the antigens. This is given when the person has been infected with the antigen and has no preivous immunity eg tetanus
Natural immunity is dispersed by the immune system in the body. It sends white blood cells out to "fight" the enemy bacteria or germs. Artificial acquired immunity is given by a doctor, usually through a needle, to disperse special kinds of immunities depending on the sickness.
explain the two types of cells that activated B cells will proliferate and differentiate into and how they work alongside the innate defense system in the bodys immune system
Artificial cloning is when you plan it and natural cloning is when it just happens

Natural Passive Immunity
Passive natural immunity
Artificial satellites are manufactured in laboratories. Natural satellites coalesced from the primordial cloud.
No, vaccinations are examples of artificial passive immunity. Natural passive immunity is passed from mother to infant either through breastmilk, or while the fetus is in utero with the transfer of antibodies from the mother through the placenta.
Active (your body produces the t-cells and b-cells): Natural- by means of infection Artificial - Passive- (develops in another person and is transferred): Natural - maternal Artificial - immunization

the difference between the 2 r that natural is the best looking or tasting and artificial is fake
passive immunity is the immunity you get from the outside of your body. got two types= natural and artificial. by means of natural, you get it from your mother's milk or from the placenta during pregnancy. The antibody that's produced in your mother's body will diffuse tru the placenta and reach the fetus. by means of artificial, you will obtain it in a from of SERUM. it's a solution containing antibodies from donors. it's very effective but lasts for short period of time.
Natural Passive Immunity

After the infection, you get naturally acquired active immunity to the chickenpox. You have a very low chance of getting chickenpox again because your immune system has made antibodies to fight off.
The difference between natural and artificial sources of light is that natural sources are produced by the sun while artificial light sources illuminate using energy from other sources and include incandescent bulbs.
