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

1 answer:

3 0

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 you write an essay about what makes a good rapper.<br> I will mark you Brainly.

DedPeter [7]

Answer:

There are many rappers out there in the world yet only a few of them are really well known and recognized. Of course this is because they meet peoples expectations. Different people have different opinions on what makes a good rapper. Things that I think make a good rapper is that they need to have good flow, meaningful lyrics that actually make sense and not just rhyme any word with another that doesn't make sense. Another thing is how they are like as a person as well. If they are a pretty decent human being and meets peoples expectations then they will be considered as a good rapper. If the person is not only ignorant but also can't rap well then they are considered bad. Like I said many people have different opinions but these are just mines.

Based on your experimental results, categorize each microbe as preferring isotonic environments, being halotolerant, or as a hal

NISA [10]

The microbes present in the experiment were:

S. cerevisiae

S. epidermis

A way of categorizing microbes is according to the environment that they need to live in. In other words, we can classify them as isotonic, halotolerant and halophile.

If we put these two microbes in solutions of increasing concentrations, 1%, 7% and 15%, we will see that:

S. cerevisiae only grows when it is in a 1% solution.

S. epidermis only grows when it is in a 1% and 7% solution.

In conclusion, S.cerevisiae prefers an isotonic environment. S. epidermis is halotolerant since it can grow in a more hypertonic environment. As none of them grows in a highly hypertonic solution, neither of them are halophile.

A man who is an achondroplastic dwarf with normal vision marries a color-blind woman of normal height. The man's father was six

Degger [83]

Answer:

1/4.

Explanation:

The autosomal dominant trait means that the trait is visible in homozygous dominant and in heterozygous condition. The X linked recessive trait will be pass down from mothers to their sons and daughters will show the trait in homozygous recessive condition only.

The man is achandroplastic dwarf ( Aa) with normal vision (XY ) is married with woman that has normal height (aa) with color blind (XhXh). They have a daughter who is dwarf ( Aa). The probability of being dwarf can be calculated by the cross Aa × aa. The offspring are Aa, Aa, aa, aa. Means 1/2 are the probability of being hetterozygous for achondroplastic . The vision probability is calculated by cross XY and XhXHh. The probability that female is heterozygous is 1/2.

So, the heterozygous probability for both trait is 1/2× 1/2 = 1/4.

Discuss the social implications of diseases

lana66690 [7]

The economic implications have to do with agriculture. Look what happens when there is an outbreak of mad cow or hoof and mouth disease. Thousands of farmers lose their herds and are financially devastated. This also affects the consumer because the decrease in supply will drive up the costs. But, it could also have the opposite effect. If consumers no longer feel safe, then they will stop eating the particular food and the farmers will lose money. The same is true with disease in plants. Tobacco mosaic virus can devastate crops, resulting in huge economic losses. On a grand scale, crop diseases can affect human history. Potato blight caused suffering and death in Ireland and resulted in massive migration. Many descendents from Irish folks in the U.S. wouldn't be here if it weren't for a crop disease.
