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:
The given blank can be filled with minimum viable population.
Explanation:
The MVP or the minimum viable population refers to the lowest number of individuals or the minimum density of the population of a species that can thrive in a specific region. The term is generally used in the fields of ecology, biology, and conservation biology.
The minimum viable population refers to the smallest probable size at which the population can prevail without encountering extinction due to demographic or natural disasters, genetic, or environmental stochasticity. Generally, MVP is utilized to signify towards a wild population, however, it can also be utilized for ex-situ conservation.
