31
Q

examples of viruses

A

common cold, flu, aids and chicken pox

32

bacteria

A

unicellular(single celled) organisms that can cause disease

33
Q

examples of bacteria

A

tuberculosis, strep

34
Q

parasites

A

an animal or microorganism that live and feed of of a host

35
Q

immune system

A

the bodys defense against disease

36
Q

how the immune system works

A

1- every pathogen has a different shaped antigen on its surface
2- once the pathogen enters a human body, the body sends out proteins called antibodies
3- antibodies that have a similar shape to the antigen will attach to the pathogen
4- white blood cells will then engulf the pathogen and destroy it

37
Q

vaccine

A

the use of a weakend or dead pathogen to induce an immune response

38
Q

how a vaccine works

A

1- get injected with a dead or weakend virus or pathogen
2- reacts to the antigen8uiu987
3- body creates antibodies against that pathogen
4- antibodies attack the vaccine particles

39
Q

how a vaccine works

A

1- get injected with a dead or weakend virus or pathogen
2- reacts to the antigen8uiu987
3- body creates antibodies against that pathogen
4- antibodies attack the vaccine particles

40
Q

allergy

A

an immune response to a usually harmless substance

41
Q

aids

A

a viral disease that attacks the immune system us now open to other infections such as pnuemonia that can cause death

42
Q

antibody

A

a protein found in the blood that is produces in response to a specific antigen

43
Q

antigen

A

substance on the surface of a pathogen that triggers an immune response

44
Q

dominant

A

the observed trait: allele masks the expressions of another allele ; expressed with a capital letter

45
Q

recessive

A

trait that can be masked by the dominant form of the trait:lower case letter

46
Q

homozygous

A

having two different allese for a particular trait(Rr)
