Answer:
The correct answer is D increasing the activity of protons pumps that lowers the pH of the cell walls allowing cells to elongate.
Explanation:
The plant growth hormone auxin work by increasing the H+ ion concentration thus decreasing the pH of the apoplast.
The decrease in the pH of the apoplast helps in the cell wall extension that ultimately result in cell growth.
Auxin hormone exert this effect by increasing the activity of increasing the activity of proton pumps in the apoplastic membrane.
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.
