Teniendo en cuenta la definición de configuración electrónica y el principio de Aufbau, el potasio K tiene una configuración electrónica de 1s²2s²2p⁶3s²3p⁶4s¹, mientras que el sodio Na tiene una configuración electrónica de 1s²2s²2p⁶3s¹
Configuración electrónicaLa configuración electrónica de los elementos es la disposición de todos los electrones de un elemento en niveles y subniveles de energía (orbitales).
Hay 7 niveles de energía, numerados del 1 al 7, y en los que los electrones se distribuyen, lógicamente, en orden según su nivel de energía. Los electrones con menos energía girarán en el nivel 1.
Cada nivel se divide en subniveles. Estos subniveles en los que se divide cada nivel pueden ser hasta 4. Estos 4 subniveles se denominan: s, p, d, f.
En el subnivel s solo puede haber un máximo de 2 electrones, en p puede haber un máximo de 6 electrones, en el subnivel d 10 electrones y finalmente en el subnivel f puede haber un máximo de 14 electrones.
En el nivel 1 solo hay un subnivel, que será el s. En el nivel 2 hay 2 subniveles, el s y el p. En el nivel 3 hay 3 subniveles s, p y d. Y en el nivel 4 hay 4 subniveles, el s, el p, el d y el f.
Principio de AufbauEl principio de Aufbau es un principio de la física atómica, que explica cómo se acomodan los electrones en sus órbitas alrededor del núcleo del átomo.
Este principio establece que el llenado de estos orbitales ocurre en orden creciente de energía, es decir, desde los orbitales de menor energía a los de mayor energía.
El más simple de los subniveles es 1. Si llena los 1, puede comenzar a llenar los 2. Una vez que se satisface el subnivel 2s, el 2p puede comenzar a llenarse y así sucesivamente.
Número atómicoEl número atómico es el número de protones que se encuentran en el núcleo de un átomo y varía de un elemento a otro, dependiendo de sus propiedades.
En un átomo eléctricamente neutro, es decir, la carga eléctrica es cero, un número de protones coincide con el número de electrones.
Este casoEn este caso, el potasio K tiene un numero atómico de 19, y considerando que es un átomo eléctricamente neutro, el elemento posee 19 protones y 19 electrones.
Entonces, teniendo en cuenta la definición de configuración electrónica y el principio de Aufbau, su configuración electrónica es:
1s²2s²2p⁶3s²3p⁶4s¹
Por otro lado, el sodio Na tiene un numero atómico de 11, y considerando que es un átomo eléctricamente neutro, el elemento posee 11 protones y 11 electrones. Entonces su configuración electrónica es:
1s²2s²2p⁶3s¹
En resumenEn resumen, el potasio K tiene una configuración electrónica de 1s²2s²2p⁶3s²3p⁶4s¹, mientras que el sodio Na tiene una configuración electrónica de 1s²2s²2p⁶3s¹

What happens when the chemical bond that holds the third phosphate is broken?
The second and third phosphate groups' chemical connection is a high energy bond. ADP is created when that link is disrupted and energy is released (adenosine diphosphate).
What is phosphate bond?
The structural structure of nucleic acids, including DNA and RNA, is composed of the sugar-phosphate backbone.
This molecule's directionality is determined by this backbone, which is made up of alternating sugar and phosphate groups.
Nucleotides make up DNA and RNA, and they are connected to one another in a chain via chemical interactions between their neighboring nucleotides' phosphate groups and sugar bases.
Therefore, The second and third phosphate groups' chemical connection is a high energy bond. ADP is created when that link is disrupted and energy is released (adenosine diphosphate).

Amino acids are named after two of their functional groups: the amino group (NH2), which acts like a base, and the carboxyl group (COOH), which acts like an acid. Amino acids also contain a third functional group, often called the R group. In alanine, the R group is a methyl group (CH3). In serine, the R group is a methyl alcohol (–CH2OH).
A molecule of alanine is shown next to a molecule of serine. Each molecular structure has an amino group (NH2) on the left side, and a carboxyl group (COOH on the right side.
What functional groups will be joined together if alanine and serine molecules combine to form a single molecule?

A. an amino group and a carboxyl group
B. two amino groups
C. an amino group and a methyl group
D. a hydrogen atom and an methyl group
The functional group alanine and serine molecules when they combine to form a single molecules an amino group and a methyl group.
What is amino acids?Amino acids are molecules that join together to form proteins. Amino acids are the building blocks of living organisms. Proteins are broken down into amino acids which is the end product of protein digestion and it is easily absorbed into the body. Amino acids help to build cells, synthesize hormone and neurotransmitters.
Amino acid is divided into essential and non essential amino acids.
The essential amino acids are not synthesised by the body but they are taken up as food supplements and they include that include leucine, isoleucine, histidine, lysine, methionine, threonine, phenylalanine, tryptophan, and valine.
Non-Essential Amino Acids are Amino acids that are synthesised by our bodies. Examples include aspartic acid, glutamic acid, alanine, glycine, tyrosine, serine.
Therefore, The functional group alanine and serine molecules when they combine to form a single molecules an amino group and a methyl group.

Cells and the organisms they make up reproduce through cell division. Some
organisms reproduce through mitosis, while others reproduce through meiosis and
fertilization. What advantage does meiosis give to organisms that reproduce sexually?
a
Meiosis ensures that offspring inherit genes from their parents.
b
Meiosis ensures that offspring will not inherit any genetic disorders.
c
Meiosis ensures that offspring are genetically different from their parents.
d
Meiosis ensures that offspring will have identical phenotypes to their parents.
The advantage meiosis give to organisms that reproduce sexually is meiosis ensures that offspring are genetically different from their parents.
What do you mean by meiosis?In sexually reproducing organisms, meiosis is a unique type of cell division that results in the production of gametes, such as sperm or egg cells.
Meiosis is a kind of cell division in physically repeating life forms that diminishes the quantity of chromosomes in gametes (the sex cells, or egg and sperm).
Gametes, or sex cells, are the end result of meiosis. Each of the four haploid daughter cells produced during meiosis has half the number of chromosomes as the parent cell.

Faris and his wife have normal skin color, but they both have a parent with albinism if
you know that albinism is a recessive trait. What is the probability that their first child
will have albinism?
Explanation:
If a man who's a carrier for albinism marries an albino what percentage of their children will be albinos, however if both parents carry the gene, there's a 1 in 4 chance that their child will have albinism and a 1 in 2 chance that their child will be a carrier. Carriers do not have albinism but can pass on the gene.

breathing involves the movement of diaphragm and Rib cage
true or false
Answer:
TrueExplanation:
It's a true statement as,
When we inhale the diaphragm moves downwards and the rib cage moves upwards and outwards to let enter the outside air containing oxygen come in.While we exhale the diaphragm comes to its position and the rib cage move downwards and inwards to let out the inside carbon-dioxide and other games out.Hence, we can conclude that breathing involves the movement of diaphragm and Rib cage.
Yes,very true! This is very true because out lungs are around our rib cage,and our lungs is where we breath. For example,right now take a breath in.....Hold.... and out. And one more time. Your lungs are moving in your rib has you do that!
