The correct answer is Robert Koch.
He was a German scientist and is globally known as one of the fathers of microbiology and bacteriology. He is famous for his work with anthrax, finding out the causative agent of the fatal disorder to be Bacillus anthracis. He received a Noble prize for his work in 1905. He also gave four postulates known as Koch's postulates.
The four characteristics that were formulated by Robert Koch to determine the causative agent of a specific disorder are:
1. The pathogen or microorganism must be must be found in all the cases of the disorder.
2. The pathogen can be withdrawn from the affected host and can be developed in pure culture.
3. The pathogen from the pure culture must result in a disease when incorporated into a vulnerable, healthy laboratory animal.
4. The pathogen must be reisolated from the novel host and demonstrated to be similar to the originally inoculated pathogen.
Answer:
probably A.
Explanation:
if I face the question A. I would answer more ten years so I think A. can fit.
B. can not be true because the most related answer would be about some organisms not plants so A. is the best choice.
In order to be considered wet, the fish should be introduced to the air first as having to be wet is where you are introduced to a water in a state that you're not in or on. The fish submerged in the water is not considered wet as this is its natural habitat.
Answer:
sinusitis
Explanation:
Sinusitis is defined as the swelling or inflammation of the linings of the tissue of sinuses. It is a condition where the cavities where the nasal cavities swells up.
The healthy nasal cavity or sinuses are always filled with air. But sometimes they get blocked and then they are filled with a fluid where bacteria germs grow and causes infection. This causes swelling up of sinuses cavities and a lot of pain is experienced by the person.
Other symptoms are runny nose, headache, nasal congestion and facial pain.
Answer:
Nucleation
Explanation:
The first step of formation of new phase, structure or self-assembly is called as Nucleation.
It is mentioned in the book of Molecular Biology of the Cell that whenever, In-vitro polymerization of micro-tubules and actin filament occur the first step is called nucleation. In other words Lag Phase.
