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>_.

Black eyes are dominant to orange eyes, and green skin is dominant to white skin. Sam, a MendAlien with black eyes and green ski

Anna [14]

<h2>The correct answer is explained below:</h2>

Explanation:

According to the given question,
For eye color, let the black color be represented by B allele and orange color be represented by b allele. Black is dominant over orange.
For skin color, let the green skin be represented by G allele and white skin be represented by g allele. Green is dominant over white.
The phenotype of Sam is black eyes and green skin so his genotype can be BBGG or BbGg. It is also said that one of his parents has phenotype orange eyes and white skin. That parent's genotype must be bbgg.
Hence, the genotype of Sam must be BbGg.
Carole has the phenotype of orange eyes and white skin. Her genotype would bbgg.
The gametes produced by Sam are: BG, Bg, bG, bg.
The gametes produced by Carole are: bg.
Mating them we get,

BG Bg bG bg

bg BbGg Bbgg bbGg bbgg

(Black/ Green) (Black/ White) (Orange/Green) (Orange/ White)

The genotypes and phenotypes (Eye color/ Skin color) obtained are represented above.
The phenotypes (Eye color/ Skin color) obtained are in the following ratio:

(Black/ Green) : (Black/ White) : (Orange/Green) : (Orange/ White) = 1 : 1 : 1 : 1

Why doesn''t the patellar reflex happen when your leg is straight?

irga5000 [103]

The patellar reflex can be defined as the kicking movement of the lower leg which occurs with a sudden twitch when the patellar tendon of a person is tapped. This patellar tendon is present below a person's kneecap. This reflex happens only when the leg is bended. It is impossible for patellar reflex to occur if the leg is straight as the quadriceps muscles are already contracted and a sudden kicking movement of the leg in such state could not be elicited. The patellar reflex protects the quadriceps from stretching too much.

How is food moved in tge gastrointestinal tract?

sesenic [268]

Answer:

Food moves through your GI tract by a process called peristalsis. The large, hollow organs of your GI tract contain a layer of muscle that enables their walls to move. The movement pushes food and liquid through your GI tract and mixes the contents within each organ.
