two Barr bodies

A Barr body is the inactivated X chromosome when in a case like this, there is more than one X chromosome for only one place. In this case, because there are two more X chromosomes than it would be normal, it will result in two Barr bodies. So, the number of Barr bodies will be <span>is always the total number of X chromosomes minus one.</span>

FromTheMoon [43]

Answer:

Based on the facts, there is no legal claim he can create against the accounting firm

Explanation:

While it is true that Alonzo had received and accepted a formal proposal by the accounting firm in Los Angeles, it only becomes valid and binding when the contract with the company is signed. Therefore, any event that occurs between the acceptance of the proposal and the signing of the contract does not generate liability in either party. Unfortunately for Alonzo, there's no potential claim agains the accounting firm that he can do.

postnew [5]

The large population of microbes that contributes to the gut microbiota and have an important role in food processing are called <u>Commensal microorganisms</u> .

The human body is host to trillions  of microbes or bacteria. Most of these are useful but may become harmful when out of control.

The microbiota consists of a wide variety of bacteria, viruses, fungi ,and other microorganisms present in a singular environment such as the human digestive tract.

<h3>Gut microbiota : </h3>

The gut microbiota is vast and complex collection of microorganisms that profoundly affects human health gut microbiota are present in the digestive tract of vertebrates including humans.

The function of gut microbiota in body function includes harvesting energy from digested food, protecting against pathogens, regulating immune system and strengthening biochemical barriers of the gut and intestine changes in microbiota composition can affects these functions.

The normal gut microbiota have specific functions like host nutrition metabolism, maintenance of structural integrity of the gut mucosal barrier, helps in immunity, protect against pathogens.

<h3>Commensal microorganisms:</h3>

Commensal microorganisms are those type of microbes that reside on either surface of the body or at mucosa without harming human health . commensal bacteria are 10 times more than the cells present in our  body.

Example - Streptococcus oralis and Streptococcus salivarius .

Commensal microorganisms plays an important role against pathogens including respiratory pathogens. It acts on the host's immune system to induce protective response that prevents colonization an invasion by pathogens. On the other hand these bacteria can directly inhibits the growth of respiratory pathogens by producing antimicrobial products .it also competing for nutrients and adhesion sites. Provides the host with essential nutrients.

<h3>What are microbes ?</h3>

Microbes are tiny living things that are found all around us and  are too small to be seen by eye. They live in soil, water and in air. The human body is the home of trillions of microbes.

In the figure below, ΔMNO≅ΔPQR.What is the measure of ∠P? Show your work and explain your reasoning.
Juliette [100K]

Answer:

\huge\boxed{\sf P = 79.5\°}

Explanation:

<u>Given that:</u>

ΔMNO ≅ ΔPQR

That means

M ↔ P

N ↔ Q

O ↔ R

So,

∠P ≅ ∠M

Given that P = 3x + 20.4 and M = 5x - 19

3x + 20.4 = 5x - 19

Add 19 to both sides

3x + 20.4 + 19 = 5x

3x + 39.4 = 5x

Subtract 3x to both sides

39.4 = 5x - 3x

39.4 = 2x

2x = 39.4

Divide both sides by 2

x = 19.7

<u>Given that:</u>

P = 3x + 20.4

P = 3(19.7) + 20.4            (x = 19.7)

P = 59.1 + 20.4

P = 79.5°

\rule[225]{225}{2}

Hope this helped!
