Answer:

D) Silent mutation on second codon, third amino acid changed from ILE to ASN.

Explanation:

Silent mutations are usually point mutation where you change one nucleotide. Since, the nucleotide changed is the third position, it does not affect the protein being manufactured (it will still put the amino acid Ala) [look up the codon redundancy on youtub.e to understand how awesome nature is!]

On the other hand, the other mutation introduced is Missense mutation where a different Amino acid is added due to change in codon (goes from ILE to ASN).

D

Methane gas is more potent( roughly by 30 times), as a greenhouse gas than carbon dioxide.

Explanation:

Greenhouse gases in the atmosphere trap infrared radiation (responsible for the transfer of heat) that reflects off of the earth's surface instead of allowing most of this radiation to escape to space. This causes heat to build up in the atmosphere. The more the greenhouse molecules are in the atmosphere the higher this effect is. Global warming is subsequently blamed for climate change around the world.

¿A qué se refiere la sexualidad libre de coerción y violencia?
kozerog [31]

Para las mujeres y las niñas, el derecho a controlar su propio cuerpo y su sexualidad sin ningún tipo de discriminación, coerción o violencia es fundamental para su empoderamiento. Sin derechos sexuales, no pueden realizar sus derechos a la autodeterminación y la autonomía, ni pueden controlar otros aspectos de sus vidas. De hecho, son los intentos de controlar la sexualidad de las mujeres y las niñas los que dan como resultado muchos de los abusos de los derechos humanos que enfrentan a diario, incluida la violencia de género, el matrimonio forzado, la mutilación genital femenina y limitaciones en su movilidad, vestimenta y educación. , empleo y participación en la vida pública. Lo mismo ocurre con las lesbianas, los hombres gay, las personas bisexuales, las personas transgénero, las trabajadoras sexuales y otras personas que transgreden las normas sexuales y de género y que, como resultado, enfrentan un mayor riesgo de violencia, estigma y discriminación. Está claro: los derechos sexuales sustentan el disfrute de todos los demás derechos humanos y son un requisito previo para la igualdad y la justicia.

A nivel mundial, existe un gran debate sobre si definir los derechos sexuales y cómo hacerlo. IWHC cree que para superar algunas de las barreras políticas al reconocimiento, respeto, protección y cumplimiento de los derechos sexuales, necesitamos aclarar cuáles son.

IWHC, en colaboración con otras organizaciones líderes de derechos humanos y salud sexual, ha desarrollado la siguiente definición de trabajo de derechos sexuales:

Los derechos sexuales abarcan ciertos derechos humanos que ya están reconocidos en las leyes nacionales, documentos internacionales de derechos humanos y otros documentos de consenso. Se basan en el reconocimiento de que todas las personas tienen derecho, libres de coerción, violencia y discriminación de cualquier tipo, al más alto nivel posible de salud sexual; perseguir una vida sexual satisfactoria, segura y placentera; tener control y decidir libremente, y con el debido respeto a los derechos de los demás, sobre asuntos relacionados con su sexualidad, reproducción, orientación sexual, integridad corporal, elección de pareja e identidad de género; ya los servicios, educación e información, incluida la educación integral en sexualidad, necesarios para ello.

Black coffee has a pH around 5; hand soap has a pH of 10. How many times more acidic is coffee relative
Anon25 [30]

Answer:

\boxed {\boxed {\sf 10^5 \ or \ 100,000 \ times \ more \ acidic}}

Explanation:

The pH scale stands for the power or potential of hydrogen. It measures how acidic or basic a solution based on the concentration of hydrogen ions and a scale from 1 to 14.

This scale is unique because it is logarithmic. So, every time the pH changes by 1 on the scale, the actual concentration of the solution increases or decreases by a tenfold.

So, a solution with a pH of 7 is ten times more acidic than a solution with a pH of 8. This can be translated to:

10^ {difference \ in \ pH}

The black coffee has a pH of 5 and the hand soap has a pH of 10. We want to find how many times more acidic coffee is, so we subtract 5 from 10 and get 5. The difference in pH is 5.

10^5=100,000

Coffee is <u>10⁵ or 100,000 times more acidic than hand soap.</u>
