When do opportunistic pathogens when the host is weakened
tend to cause disease?
Who showed that biogenesis is Louis Pasteur
responsible for the propagation of
life?
Robert Koch helped establish the introduce the bacteria into a new mouse to see if it
germ theory of disease by discovering established the same infection
that anthrax was caused by a bacterial
microorganism. After he isolated and
purified the same bacteria from
several diseased animals, what would
be the next step in order to show that
this bacterium caused anthrax?
How many principles are there in 4
Koch's postulates of disease?

Which of the following microscopic
techniques would be most
appropriate?
An atom is best described as the smallest unit of an element
Isotopes are atoms of the same the number of neutrons found in the nucleus
element that differ in
A feature of many of the isotopes that The nucleus of the isotope is unstable and decays
are used in the field of medicine is that over time.
the isotopes are radioactive. What
does this mean?
The pictured molecules all contain six Isomers
carbon atoms, twelve hydrogen
atoms, and six oxygen atoms
(C6H12O6). However, these atoms are
arranged differently in each molecule.
