How come one type of matter can be converted to a totally different one?
wariber [46]

Answer:

Explanation:

En física, la materia es todo aquello que se extiende en cierta región del espacio-tiempo, que posee energía y está sujeto a cambios en el tiempo y a interacciones con aparatos de medida. Se considera que es lo que forma la parte sensible de los objetos perceptibles o detectables por medios físicos.

Etimológicamente, proviene del latín materia, que significa «sustancia de la que están hechas las cosas» y que también alude a la «madera dura del interior de un árbol»;1​ la palabra está relacionada con māter («origen, fuente, madre»)2​ y se corresponde con el griego hyle3​ (de hylos: «bosque, madera, leña, material»)4​5​ que es un concepto aristotélico de la teoría filosófica del hilemorfismo.6​

El uso moderno del término va más allá de la noción clásica de sustancia, y los físicos denominan materia a cualquier entidad cuya presencia en una cierta región del espacio-tiempo conlleva que el tensor energía-impulso para dicha región es diferente de cero.

Answer: The genotype ratio of offsprings of a cross between one homozygous tall plant and one heterozygous tall plant is 2TT:2Tt

The phenotype ratio is that all offsprings will be tall.

The genotype ratio of a cross between two heterozygous red flowers is 1RR:2Rr:2rr. The phenotype ratio is 3 Red flowers: 1 white flower.

Explanation: From the information given, tall is dominant and short is recessive while red is dominant and white is recessive.

Let T represent the allele for tall height, t represent the allele for short height, R represent allele for red flowers and r represent allele for white flowers.

The genotype of a homozygous tall plant is TT, the genotype of a heterozygous tall plant is Tt, the genotype of a heterozygous red flowered plant is Rr.

The possible genotypes of offsprings of a cross between one homozygous tall plant and one heterozygous tall plant are TT and Tt.

Tt will manifest outwardly as tall because T is dominant over t. Therefore, all the offsprings will be tall.

The possible genotypes of a cross between two heterozygous red flowers are RR, Rr and rr. RR will manifest as red, Rr will also manifest as red because R is dominant to r while rr will manifest as white because white allele (r) is recessive. Therefore 3 plants will be red-flowered while 1 plant will be white flowered.

See the attached punnet squares for details of the cross.
