Answer:
4. The suspected causative agent must be isolated from the diseased host and grown in pure culture
Explanation:
Robert Koch (1843-1910) was one of the most important bacteriologists of all time. Famous for discovering the tuberculosis bacillus (precisely on March 24, such as today, in 1882), he also discovered the cholera bacillus and is considered the founder of bacteriology. He worked on the isolation of infectious agents and reinfections from pure cultures, experiences from which he established the "Koch Postulates".
These postulates have been taken as a reference that describes the etiology of all the causative agents of an infectious disease, although they were originally used to describe only the tuberculosis bacillus. They are the following:
1- The agent must be present in each case of the disease and absent in the healthy.
2- The agent should not appear in other diseases.
3- The agent must be isolated in a pure culture from the lesions of the disease.
4- The agent has to cause the disease in an animal that can be inoculated

Answer:
Incomplete dominance
Explanation:
Incomplete dominance is a condition observed in the organisms while studying their genetics.
When the organisms with two alleles for the same trait are crossed, then neither of the two alleles completely express themselves but a new variation of the trait is formed.
This can be observed in the given scenario also when the ed and white flowers are crossed, then the pink flowers (a new variation of the trait) is formed called blended trait.
Thus, incomplete dominance is correct.
Hello there,
As from what I can recall, I can remember 4 concerns regarding nuclear energy
1) Storing radioactive waste
2) Safety
3) Weapons proliferation and terrorism
4) Health
Hope this helps ;))
