Communicable Diseases

Bacteria create Toxins and the White blood cells create Anti-toxins neutralize the effect of the toxins produced by bacteria
Types of microbes are fungi, viruses, bacteria and prototist
Bacteria can produce a waste product, toxins are there reason you feel bad, if it is in your blood stream it can become widespread, they are single cells, drugs help, e.g. food poisoning and cholera
Diseases spread by Direct Physical Contact, Sneezing, Air, Food, Water, Body fluids, Unclean Objects
Virus is genetic info with protein, very harmful, in tissues, e.g. Measles and influenza
Fungi, e.g. Athletes foot
Micro organisms invade the body and white blood cells engulfs them and ingests them so they a digested and destroyed
Antigens are found on the surface of the microorganism and when detected by white blood cells, antibodies which lock on the antigens this causes them to clump together so they can be digested by white blood cells, "Phagocytosis"
Vaccinations can protect you from diseases by immunization, this is done b giving you a vaccine

Herd Immunity is the resistance to the spread of a contagious disease within a population that results if a sufficiently high proportion of individuals are immune to the disease, especially through vaccination.
Antibiotic Resistance is when a bacteria that was treatable with antibiotic and were killed and is no longer affected by drugs
Double blind trials is important to be certain that a drug really does have positive effects, rather than people feeling better simply because they expect to feel better if they take a medicine. This is called the placebo effect. Only the researcher knows which is which
A Placebo is a medicine or procedure prescribed for the psychological benefit to the patient rather than for any physiological effect.
Monoclonal Antibodies are made form a single clone of cells, these are specific with binding sites on antigens and able to target specific parts
Monoclonal Antibodies are used in Drugs screenings, Labs, Treating Cancer, Research and Identification and plant diseases
Nitrogen is used for protein growth, Magnesium is used is used to make chlorophyll
To find plant disease you can check a manual or a website, send sample to be tested or buy testing kits

Signs of disease are Yellows leaves/colour change,withering, dropping leaves, dis-formed, spots
