Answer:
Cells from the pure culture can cause disease in healthy individual after infecting it with the pure culture.
Explanation:
Koch postulates says that microbes are the cause of every disease. These microbes can be isolated from the infected host and can be grown outside the host in a pure culture. Then this pure culture is able to cause disease in a healthy host after infecting the host with pure culture. Then this same microbe can again be isolated from the second host.
So Koch postulates which proves that cells from the pure culture can cause disease in healthy individuals after infecting it with the pure culture was the step that enabled Koch to determine that a particular microbe is the cause of the disease because it was causing disease in healthy individual also.
Answer:
Covalent
Explanation:
A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms.
In terms of density, the oceanic crust is denser than continental crust, which also means it is heavier.Density is important in the formation of layers on Earth. Because continental crust is less dense, it floats higher than oceanic crust. If the two will have different densities, then continents will be submerged in the ocean.
C. they created the globe after they realized it was round
The answer is <span>The name includes the genus and species.
</span>In binomial nomenclature, the name of the species consists of two (Greek: bi-) word. The first word indicates the genus classification of an organism and the second word indicates the species within a genus. For example, Latin name for a white oak is Quercus alba. The first word indicates that the species belongs to the genus Quercus. The second word 'alba' indicates the name of the species within the genus Quercus.
