Q

What causes fermentation?

A

yeast

19
Q

germ theory of disease

A

some diseases are caused by specific germs called pathogens

20
Q

What did Robert Koch study?

A

etiology of disease using petri dishes and staining

21
Q

What is the most widely used staining technique and why?

A

Gram’s stain because it can differentiate between bacteria types

22
Q

What are Koch’s postulates?

A

-the suspected causative agent must be found in every case of the disease and be absent from healthy hosts
-agent must be isolated and grown outside the hosts
-when the agent is introduced to a healthy host and host must get the disease
-same agent must be found in the diseased experimental hosts

Ehrlich

A

started the field of chemotherapy

29
Q

Why might Nightingale be considered the Mother of Nursing?

A

she founded modern nursing and saved tons of patients

30
Q

What are the basic chemical reactions of life?

A

biochemistry

31
Q

How can biochemistry be applied?
