A pair of mice are bred several times generating the following data table. What are the most likely genotypes of the parents?
Answers
Answer:
This question lacks options, the options are:
A) FF and ff
B) FF and Ff
C) Ff and Ff
D) Ff and ff
The answer is D (Ff and ff for parent 1 and 2 respectively)
Explanation:
This question depicts a single gene coding for fur colour in mice. The gene controls two traits, black fur and white fur, encoded by alleles F and f respectively.
According to the question, a pair of mice has been bred several times to generate the same data of 22 black fur and 23 white fur mice. Based on this data, it shows that the phenotypic ratio of black to white mice is 1:1.
To get a 1:1 phenotypic ratio of black fur offspring to white fur offspring, the parents mice must have genotypes Ff (heterozygous) and ff (same recessive alleles).
In a cross between parents Ff × ff (see punnet square), offsprings with the following genotypes will be produced: Ff, Ff, ff and ff. Ff is black furred while ff is white furred.
Ff (2) : ff (2) is equivalent to Ff (1) : ff (1).
Hence, a data of 22 black mice and 23 white mice which represents a 1:1 ratio will only be produced by parents mice with genotypes: Ff and ff.

Answers
Answer:
natural selection leads to evolution
Explanation:
Natural selection leads to evolution. Therefore, the correct statement is option A.
What is natural selection?Evolution is a result of natural selection. Natural selection is an evolutionary mechanism that rewards people with specific features that help them live and procreate more successfully than those lacking such traits. New species evolve as a result of an increase in the frequency of these favorable features in the population throughout time.
Natural selection is a major force behind evolution in this way. However, other processes, such genetic drift, gene flow, and mutation, can also lead to evolution.
Natural selection and evolution are separate but closely connected ideas. It is one of the mechanisms that propels evolutionary change through time; as such, it is a mechanism of evolution. It acts on the genetic variation present in a population, favoring traits that increase an organism's reproductive success in a given environment.
Therefore, natural selection leads to evolution.

What is the number of this particle in a phosphorus atom?
Ap ex
Answers
Answer:
Fósforo
Símbolo P, número atómico 15, peso atómico 30.9738. El fósforo forma la base de gran número de compuestos, de los cuales los más importantes son los fosfatos. En todas las formas de vida, los fosfatos desempeñan un papel esencial en los procesos de transferencia de energía, como el metabolismo, la fotosíntesis, la función nerviosa y la acción muscular. Los ácidos nucleicos, que entre otras cosas forman el material hereditario (los cromosomas), son fosfatos, así como cierto número de coenzimas. Los esqueletos de los animales están formados por fosfato de calcio.
Cerca de tres cuartas partes del fósforo total (en todas sus formas químicas) se emplean en Estados Unidos como fertilizantes. Otras aplicaciones importantes son como relleno de detergentes, nutrientes suplementarios en alimentos para animales, ablandadores de agua, aditivos para alimentos y fármacos, agentes de revestimiento en el tratamiento de superficies metálicas, aditivos en metalurgia, plastificantes, insecticidas y aditivos de productos petroleros.
De casi 200 fosfatos minerales diferentes, sólo uno, la fluoropatita, Ca5F(PO4)3, se extrae esencialmente de grandes depósitos secundarios originados en los huesos de animales y que se hallan en el fondo de mares prehistóricos, y de los guanos depositados sobre rocas antiguas.
La investigación de la química del fósforo indica que pueden existir tantos compuestos basados en el fósforo como los de carbono. En química orgánica se acostumbra agrupar varios compuestos químicos dentro de familias llamadas series homólogas.
Esto también puede hacerse en la química de los compuestos de fósforo, aunque muchas familias están incompletas. La familia mejor conocida de estos compuestos es el grupo de cadenas de fosfatos. Las sales de fosfatos constan de cationes, como el sodio, junto con cadenas de aniones, como (PnO3n+1)(n+2)-, que pueden tener de 1 a 1 000 000 de átomos de fósforo por anión.
Los fosfatos se basan en átomos de fósforo rodeados en una disposición tetraédrica por átomos de oxígeno, el miembro más pequeño de la familia es el anión simple PO3-4 (el ion ortofosfato). La familia de las cadenas de fosfato se basa en hileras alternadas de átomos de fósforo y oxígeno en que cada átomo de fósforo permanece en el centro de un tetraedro de cuatro átomos de oxígeno. Hay también una familia estrechamente relacionada de fosfatos cíclicos.
Una característica estructural interesante de muchos de los compuestos del fósforo conocidos es la formación de estructuras tipo jaula. Ejemplos de estas moléculas son el fósforo blanco, P4, y uno de los pentóxidos de fósforo, P4O10. Las estructuras tipo red son comunes; por ejemplo, los cristales de fósforo negro en que los átomos están enlazados unos con otros.
En la mayor parte de sus compuestos, el fósforo está enlazado químicamente a cuatro átomos inmediatos. Hay gran número de compuestos en los que uno de los cuatro átomos está ausente y en su lugar hay un par de electrones no compartidos.
Hay también unos cuantos compuestos con cinco o seis átomos unidos al fósforo; son muy reactivos y tienden a ser inestables. Durante los años 60 y 70, se prepararon muchos compuestos orgánicos de fósforo. La mayor parte de estas estructuras químicas incluye tres o cuatro átomos enlazados al fósforo, pero existen también estructuras con dos, cinco o seis átomos unidos a cada átomo de fósforo.
Casi todo el fósforo utilizado en el comercio está en forma de fosfatos. La mayor parte de los fertilizantes fosfatados constan de ortofosfato diácido de calcio u otofosfato ácido de calcio muy impuros, Ca(H2PO4)2 y CaHPO4. Estos fosfatos son sales del ácido ortofosfórico.
El compuesto de fósforo de mayor importancia biológica es el adenosintrifosfato (ATP), que es un éster de la sal, el tripolifosfato de sodio, muy utilizado en detergentes y ablandadores de agua. Casi todas las reacciones en el metabolismo y la fotosíntesis requieren la hidrólisis de este tripolifosfato hasta su derivado pirofosfato, llamado adenosindifosfato (ADP).
Efectos del Fósforo sobre la salud
El Fósforo puede ser encontrado en el ambiente más comúnmente como fosfato. Los fosfatos son substancias importantes en el cuerpo de los humanos porque ellas son parte del material de ADN y tienen parte en la distribósforo que es conocida. Cuando el fósforo blanco ocurre en la naturaleza este puede ser un peligro serio para nuestra salud. El fósforo blanco es extremadamente venenoso y en muchos casos la exposición a él será fatal. En la mayoría de los casos la gente que muere por fósforo blanco ha sido por tragar accidentalmente veneno de rata. Antes de que la gente muera por exposición al fósforo blanco ellos a menudo experimentan náuseas, convulciones en el estómago y desfallecimiento. El fósforo blanco puede causar quemaduras en la piel, dañar el hígado, corazón y riñones.

We need these amino acids to survive because they make up proteins, and proteins perform pretty much every crucial function you can think of, ranging from defense to cell signaling to structure. All biomolecules are important in cell function -- carbs are needed for your cells to burn for energy via cellular respiration (a process that yields app. 28-32 ATPs per cycle), lipids are needed for cell membranes (amongst numerous other needs), proteins are needed for the reasons above, and nucleic acids are needed for RNA and DNA.
