Answer:
The correct answer is "Koch's postulates".
Explanation:
The missing options of this question are:
a) spontaneous generation
b) Koch's postulates
c) epidemiology
d) vaccination
The correct answer is option b) "Koch's postulates".
Koch's postulates propose four criteria used to establish that a pathogen is responsible for a disease. In his famous experiments, Robert Koch was able to prove that <em>Bacillus anthracis</em> is the cause of anthrax by injecting to a mouse an isolated culture from the blood of an injected sheep. The scenario established in the question is very similar to anthrax, and the scientific approach to look for the pathogen of the disease is following the principles of Koch's postulates.
Answer:
<em>The correct option is 'Nitrogen has a larger radius and one less proton than oxygen.'</em>
Explanation:
Atomic number can be described as the number of protons in an atom. The atomic number of nitrogen is 7. This means that nitrogen has seven protons in its nucleus.
The atomic number of oxygen is 8 which means oxygen has 8 protons in its atom. Hence, oxygen has one more proton than a nitrogen atom.
The radius of an atom decreases when moving from left to right in the periodic table. Hence, the radius of nitrogen will be larges as compared with oxygen.
