pathogens can spread through direct contact, water, air
4 types of bacteria pathogens,bactiria, fungi,protits
-
viruses make you ill by rapidly producing in your cell which will damage or burst your cell destroying it
three examples of viral disease are measles, HIV tobacco mosaic virus
two examples of viral disease are salmonella,gonnarea
an example of a protists disease malaria caused by a protist pathogen that is spread from a person to a person by mosquito bites and causes recurrent fevers
a communicable disease is a disease that can be spread from one organism to another
an incommunicable disease is where it cant be spread from one organism to another
four methods of controlling the spread of communicable disease is good hygiene isolating infected individuals controlling vectors and vaccinating people
an example of a fungal disease in plants is rose black spot spread by water and wind it affects plants growth because it reduce the plants of photosynthesis
the cause of plant disease can be identified by using gardening manuals and websites, labotory testing monoclonal antibody's kits
plant disease can be identified by seeing if the plant has areas of decay discoloration, growths , ,malformed stems or leaves , presence of pests, spots on leaves and stunned growth
what happens during phagocytosis well phagocyte is attracted to the area of infection, engulfs a
pathogen, and releases enzymes to digest the pathogen
What three functions do white blood cells have phagocytosis, producing antibodies, producing antitoxins
-
antibody are a specific defence because they are have to be the right shape to fit the unique antigens so they target a specific
antigen they do this by blinding to them
-
-
a vaccination helps protect against a specific pathogen because vaccination simulates the body to produce antibody's against a specific pathogen - if the same pathogen renters the body white blood cell rapidly produce the correct antibody
herd immunity is were most of a population is vaccinated against a disease meaning it is less likely to be spread
-

-
What properties of new drugs are clinical trials
designed to test
toxicity, efficacy, and optimum dose
What happens in the pre-clinical stage of a drug trial the drug is tested on a cell or apiece of tissue then on animals
a placebo is a medicine with no affect that is given to patients instead of the real drug in a trial
a double-blind trial is a trial were neither the patient nor doctor knows who receives the real drug or who receives the placebo
