Answer:

31 electrons.

Explanation:

Atoms initially have a neutral charge. So if this atom were neutral, it would have 29 electrons to balance out with the 29 protons. Protons are never added or removed. Since this atom has a -2 charge, that means it is an anion with 2 additional electrons. 29e- + 2e- = 31e-

¿De qué manera la familia de los ARN, por la función que cumplen, colaboran con el ARN viral?
Zarrin [17]

Answer:

Los ARN de nuestro organismo pueden acoplarse con los ARN virales.

Explanation:

En las infecciones virales donde los virus presentan ARN, los virus pueden acoplar su informacion al ARN humano sin que nuestro organismo lo perciba, es asi que consiguen la produccion de sus proteinas ya que de otra manera se les seria imposible.

Un virus no tiene un mecanismo de traducciondel codigo ribonucleico, consolidacion  de proteinas y replicacion de ARN, es por eso que al acoplarse al ARN humano aprovecha estos mecanismos y multiplica sus estructuras proteicas junto con las proteinas celulares  de la celula huesped que infecto, desencadenando patologia de la misma celula.

A chef is going to use a mixture of two brands of italian dressing. the first brand contains 7% vinegar, and the second brand co
faust18 [17]

Answer is: 180 mL of 7% vinegar and 60 mL of 11% vinegar.

ω₁ = 7% ÷ 100% = 0.07.<span>
ω</span>₂ = 11% ÷ 100% = 0.11.<span>
ω</span>₃ = 8% ÷ 100% = 0.08.<span>
V</span>₁ = ?.

V₂ = ?.<span>
V</span>₃ = V₁ + V₂.
V₃ = 240 mL.

V₁ = 240 mL - V₂.<span>
ω</span>₁ · V₁ + ω₂ ·V₂ = ω₃ · V₃.

0.07 · (240 mL - V₂) + 0.11 · V₂ = 0.08 · 240 mL.

16.8 mL - 0.07V₂ + 0.11V₂ = 19.2 mL.

0.04V₂ = 2.4 mL.

V₂ = 2.4 mL ÷ 0.04.

V₂ = 60 mL.

V₁ = 240 mL - 60 mL.

V₁ = 180 mL.
