Answer:

The correct answer is 20...

Explanation:

The name of these 20 common amino acids is as follows: alanine, arginine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, histidine, isoleucine, leucine, lysine, methionine, phenylalaine, proline, serine, threonine, tryptophan, tyrosine, and valine. Alanine.

Although their is 20 altogether their is only 9 main essential ones:

The 9 essential amino acids are leucine, iso-leucine, valine (all BCAAs), lysine, histidine, phenylalanine, methionine, threonine, and tryptophan. Essentials amino acids are important because they serve as the "building blocks" for muscle protein. They are also are what makes a protein a "complete" protein.

Stella [2.4K]
It is important to make the client understand that while alcohol might not be the cause of their problems or all of their problems it does affect the process of their decision making depending on the situation and how they feel towards different situations. A short-term goal would be to go a week without drinking alcohol and to note their changes in mood, behavior towards others and different challenges that they face. Another option is to set a "challenge" to see how long the client can go without the consumption of alcohol, the longer they go without the bigger the changes they will see in their day to day life.

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!
