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>_.

Can anyone explain to me the "all or nothing law" of action potentials? I'm in a college physiology class, and I do not understa

AysviL [449]

The all or nothing law of action potentials mainly talks about how the axons in the neurons only fire when there is enough action potential to fire. If there is not enough action potential, then the neuron will not be able to send signals because the action potential does not fire because of the deficit.

Energy convention: Convection is the motion of a fluid driven by temperature differences across that fluid. When a fluid is heated, the region in closest contact with the heat source becomes less dense due to increased kinetic energy in the particles. Convection is one of the fundamental ways that heat is transferred

Two different mature mRNA transcripts are produced from this gene, one is approximately 2000 nucleotides long, the other is appr

klemol [59]

Answer:

Alternative splicing explains how it works

Explanation:

Two different transcripts can be produced from one single gene according to the nature of exons and introns of every transcript, which means that a group of exons will form the future mRNA molecule. The nature of this phenomenon is based on the function and local that every transcript will act. These mRNA transcripts are the result of how the RNA polymerase and transcription factors interacts with DNA molecule and therefore selects the number and the size of the exons and introns of each mature mRNA transcript.

How is fur helpful for organisms living in cold environments?

garri49 [273]

Fur has a thick layer of protection to help protect..say a bear in this case. A polar bear's fur is helpful in the cold, to prevent the bear from freezing to death.

But since a polar bear eats fish and things that it's used to in Antarctica, it probably won't adapt as easily.

I hope I helped!
