The microorganism must be isolated from a diseased organism and grown in pure culture.

The cultured microorganism should cause disease when introduced into a healthy organism.

The microorganism must be reisolated from the inoculated, diseased experimental host and identified as being identical to the original specific causative agent.

What are the two factors that affect the friction between two surfaces
BabaBlast [244]

Answer:

The two factors are:

• The kind/type of surface involved.

• The force that the surface are being pushed together.

Explanation:

Friction can be said to be the general term used to describe the force that one surface exert on another when they rub against each other.

When the surface is partially not smooth or totally rough, a greater force is been needed to move one surface past the other.

The weight of the can also significantly be a key factor. This is where the need to friction reduction come to play a role; and need for friction reducers like lubricant, rollers etc helps.

A population in which the frequency of alleles remains the same over generations is said to be in genetic equilibrium. Describe
DochEvi [55]

Answer:

Natural selection disrupts the genetic equilibrium by favoring the genes for the traits that impart survival advantage to individuals.

Explanation:

Natural selection refers to the unequal survival rate of individuals of a population due to the presence of some beneficial adaptive genetic trait. These individuals are able to survive more and leave more progeny. Over generations, the population has increased number of these individuals leading to evolution of a population with different allele frequencies.  

For example, the frequency of gene for antibiotic resistance in the bacterial population was increased once humans started using antibiotics to control the bacterial population. This led to the evolution of the bacterial population with antibiotic resistance.
