Ƒ An atom that gains one or more electronswill have a NEGATIVE charge. ƒ An atom that loses one or more electrons will have a POSTIVE charge. ƒ An atom that gains or losesone or more electrons is called an ION. ƒ A positive ion is called a CATION and a negative ion is called an ANION.

From this information above you can see its negative so it means it gets reduced
hope it helped

In this reaction the lead atoms gain anelectron (reduction) while the oxygen loses electrons (oxidation). Magnesium loses electrons and is therefore said to be "oxidized", whereas the chlorines gain electrons and are said to be reduced
and as you can see oxidation only happens when oxygen is reduced

Debido a la baja cantidad de calorías que utilizamos o quemamos en un día de trabajo
Delvig [45]

Answer: Se debe a que el cuerpo lleva a cabo funciones fisiológicas vitales que requieren energía.

Explanation:

Las calorías son unidades de energía aportadas por los alimentos que consumimos a diario. Puntualmente se define la cantidad de calor necesaria para aumentar en 1 grado centígrado a la temperatura de 1 gramo de agua desde 14,5 hasta 15,5. La principal fuente de calorías en los alimentos son los hidratos de carbono, luego le siguen las grasas y proteínas.

<u>Dicha energía hallada en los alimentos, es utilizada por el cuerpo para llevar a cabo distintas funciones fisiológicas vitales e importantes para que el organismo funciones correctamente</u>, como el bombeo de sangre del corazón, funcionamiento de los riñones o el actividad del cerebro, etc. Nos referimos a esto como el metabolismo basal, el cual es el valor mínimo de energía utilizada en reacciones químicas celulares para la supervivencia del organismo. Dicho metabolismo basal depende de diversos factores tales como la edad, peso, sexo, etc. Pero también, las calorías son necesarias para distintas actividades voluntarias como caminar o levantar algún objeto.

<u>Sin embargo, la forma de energía de las calorías de los alimentos es distinta a la forma de energía necesaria para llevar a cabo estas funciones fisiológicas tanto voluntarias como involuntarias.</u> Para ello, la energía de las calorías debe de convertirse a otra forma y esto ocurre comenzando primero con la digestión de los alimentos, donde luego sus nutrientes son absorbidos en el torrente sanguíneo para luego dirigirse a las células. En las mismas, ocurre un proceso llamado respiración celular, en donde se utilizan las calorías de los alimentos para sintetizar ATP (Adenosín Trifosfato), la cual es una molécula que almacena energía utilizable por parte de las células y que eventualmente impulsará y llevará a cabo todos los procesos fisiológicos y metabólicos.

Entonces, en el caso del trabajo de una oficina en el que las personas permanecen sentadas largas horas, sin mucha actividad, <u>igualmente necesitan consumir mas de 2.000 kilocalorías diarias ya que el cuerpo debe obtener esa energía para llevar a cabo las funciones de todos los órganos para mantenerlos vivos.</u>

The structure of aba is shown below. why was this a suitable substitution for a cys residue? under what circumstances would it n
Inessa [10]

Answer and explanation;

-Aba is a suitable replacement because Aba and Cys have approximately the same sized side chain and are similarly hydrophobic.

-However, Aba cannot form disulfide bonds so it will not be a suitable replacement if these are required.

-Alpha-Aminobutyric acid is biosynthesized by transaminating oxobutyrate, a metabolite in isoleucine biosynthesis.

Bone can be classified as a connective tissue because it contains an extracellular matrix that surrounds widely spaced cells. Tr
kotykmax [81]

Answer:

False. Bone can be classified as a connective tissue because it provides support and structure to the body.

Explanation:

Connective tissue is those tissues that fill spaces between organs and other tissues, and also provide support to the organism. It is characterized by the presence of different types of cells separated by intercellular material synthesized by them.

The bony tissue is the principal structural and supportive connective tissue that differs from the other connective tissues because its extracellular matrix is mineralized, which makes it possible to accomplish its support and protection function due to its rigidity and hardness. The mineral that deposits in the osteoid matrix is the calcium phosphate, composing hydroxyapatite crystals. The bony tissue is a storage site of calcium and phosphate, which are available for maintaining constant the calcium blood levels according to the individual physiological needs.
