Primary succession occurs<span> in essentially lifeless areas or regions in which the soil is incapable of sustaining life as a result of such factors as lava flows, newly formed sand dunes, or rocks left from a retreating glacier. Hope this answers the question.</span>

When the resident microbiota prevents the establishment of a pathogen, it is called _______.

Ksju [112]

Microbial antagonism is the inhibition of pathogens growth by antagonist microbiota. When the resident microbiota prevents the establishment of a pathogen, it is called <u>Microbial antagonism</u>.

<h3>What are antagonist microbiota?</h3>

Antagonist microbiota are the organisms, like bacteria or fungi, capable of acting as a biological control to avoid other pathogenic agents' establishment.

These organisms share three characteristics,

a) capability to quickly colonize a new surface and effectively persist on it

b) better ability than the pathogen to get nutrients

c) the capability of surviving under different environmental conditions.

These antagonists are

genetically stable,
their nutritious requirements are not demanding,
they are capable of surviving under adverse environmental conditions,
they have a high reproductive capability, and
are not pathogenic to their host.

The mechanisms these antagonists use to inhibit the pathogen growth and establishment are among others, antibiosis, competition for resources, lytic enzyme production, and parasitism.

When the resident microbiota prevents the establishment of a pathogen, it is called _<u>microbial antagonism</u>_.

A man and woman are deciding whether to have a child. The genotype of

LUCKY_DIMON [66]

Answer:

No, the child cannot inherit the disease.

Explanation:

The problem tells you that the man has a recessive allele for an inherited disease, but he has a normal phenotype. This means that the disease is recessive and in order for an individual to have the disease, they must have two recessive copies of the allele. The problem also tells you that the mother has a genotype that does not include this allele. With this information, you can do a punnet cross of BB (mother) x Bb (carrier father), and end up with the following possible genotypes: BB, Bb, BB, Bb. Therefore the child will not have the disease, but there is a 50% chance that the child will be a carrier for the disease.
