dead or inactive cells
18

19

20
What are antibiotics?
drugs that work by preventing treating or curing symptoms of a disease
21
Name the cells that make you immune to a disease
antibodies
22
DNA is made up of what features
made up of two strands, strands are joined by DNA bases, strands are twisted together to form a double helix shape
23
How does a vaccine work?
a vaccine contains dead or inactive forms of a disease causing micro organism (a micro organism that cannot make you ill) the micro organism tricks your body into thinking that the harmful active form of the disease has entered your body
24
What is a pathogen
a harmful microorganism
25
Short sections of DNA are know as
genes
26
Who created the first vaccine?
edward Jenner
27
What is the meaning of immune?
resistant to a disease
28
What’s a seed bank
a way of conserving plants
29
Why do people choose not to have some vaccines?
safety of the vaccines and possible side effects
30
Each gene contain the
code or instruction for a characteristic
31
How can animals become extinct?
loss af habitat, space, food, and water
32
Who invented penicillin?
Alexander Fleming
33

smallpox
34
Darwin and Wallace checked each others work this is an early example of
peer view
35
Antibiotics work by…
killing the bacteria that made you ill
36
What is an immunisation
a way of inserting a vaccine into the body
37
State what is meant by conservation
protecting a natural environment to ensure that habitats are not lost
38
Advantages being immunised
protection
39
State what is meant by mutation
when bacteria multiply their DNA can be damaged or altered
40
Why are dead or inactive micro organisms used in vaccines?
they are harmless
41
Mutation usually makes bacteria DIE but sometimes it can help it by….
the mutation causing the bacteria to be resistant to an anti biotic like a super bug
42
What are the four DNA bases
ATCG (adenine, thymine,cytosine,guanine)
