Answer 1

Answer:

A. They have identical DNA in all of their cells.

Explanation:

Identical twins are also known as monozygotic twins. They result from the fertilization of a single egg that splits in two. Identical twins share all of their genes and are always of the same sex. In contrast, fraternal, or dizygotic, twins result from the fertilization of two separate eggs during the same pregnancy.

Trastorno alimenticio caracterizado por una gran pérdida de peso, que el propio paciente se provoca y que puede conducir a un estado de inanición.

Answers

Answer: Anorexia nerviosa.

Explanation:

La anorexia nerviosa es un trastorno o desorden alimenticio en donde se produce un rechazo de la comida debido a un temor excesivo a subir de peso, llegando a un estado de inanición serio. Entonces, se produce un deterioro en la salud y una debilidad causada por una ingesta insuficiente de nutrientes causando una desnutrición que altera diversas funciones del organismo. Es mas común en mujeres jóvenes o adolescentes aunque se reportan casos en ambos sexos y a cualquier edad. No debe confundirse con otro trastorno llamado simplemente anorexia, que es un síntoma que se caracteriza por una falta de apetito debido a alguna causa orgánica.

Este trastorno puede ocurrir por diversas causas que vienen acompañadas por una distorsión de la imagen corporal propia, en donde la persona considera que debe perder más peso de lo que se considera saludable y normal para su edad y estatura, llegando a estados raquíticos. También hay muchos casos en donde además de una dieta extrema, se realice ejercicio de manera excesiva o que utilicen otros métodos para bajar de peso como el abuso de laxantes u otros medicamentos.

 Algunos factores de riesgo para el desarrollo de la anorexia nerviosa pueden ser:

Personalidad perfeccionistaImagen propia negativa o baja autoestimaPresiones socialesPadecer algún trastorno de ansiedad

A molecule of carbon dioxide (CO2) is made up of one carbon atom and two oxygen atoms.

Answer:a colorless, odorless gas produced by burning carbon and organic compounds and by respiration. It is naturally present in air (about 0.03 percent) and is absorbed by plants in photosynthesis.

D. Mitosis

Answers

Answer:

A. General Cell Processes

B. Growth

C. DNA Replication

Explanation:

During interphase, the cell grows and makes a copy of its DNA. During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells.

During interphase, the cell grows and makes a copy of its DNA. During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells. So, the option A, B and C are correct.

What do you mean by interphase?

Interphase is the portion of the cell cycle that is not accompanied by visible changes under the microscope, and includes the G1, S and G2 phases. During interphase, the cell grows, replicates its DNA and prepares for mitosis.

A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.

Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis. During mitosis, chromosomes will align, separate, and move into new daughter cells.

When a genotype of a guinea pig is "Hh" (select all that are true)

One chromosome of the homologous pair has a sequence that results in hair and one chromosome has a sequence that results in no hair

One copy of the "H" allele on the homologous chromosome is enough to make the guinea pig have hair since both alleles are transcribed and translated

Only one of the chromosomes in the homologous pair carry the genetic sequence to make hair

Both chromosomes in the homologous pair carry the genetic sequence to make hair

Answers

Answer:

One chromosome of the homologous pair has a sequence that results in hair and one chromosome has a sequence that results in no hair

One copy of the "H" allele on the homologous chromosome is enough to make the guinea pig have hair since both alleles are transcribed and translated

Only one of the chromosomes in the homologous pair carry the genetic sequence to make hair

Explanation:

Hairy is dominant over hairless. If there was a hairless guinea pig here instead, we would know its genotype. It would be hh. Remember any time a dominant allele is present it is expressed in the phenotype, so if the phenotype is not the dominant one, we know the genotype must contain two recessive alleles.

These are the factors that is true, When a genotype of a guinea pig is "Hh"

• One chromosome of the homologous pair has a sequence that results in hair and one chromosome has a sequence that results in no hair

• One copy of the "H" allele on the homologous chromosome is enough to make the guinea pig have hair since both alleles are transcribed and translated

• Only one of the chromosomes in the homologous pair carry the genetic sequence to make hair

Comparing the four most common types of power plants in Alberta (coal, natural

gas, wind, and hydroelectric), which has the lowest efficiency in electricity

generation? and why?

Answers

Answer:

Coal.

Explanation:

Steam power plant has the lowest efficiency in electricity production which can only be run with the use of fossil fuels such as coal. The efficiency of this power plant is the lowest because large amount of coal is converted into smoke and other gases and very less amount of coal into heat energy. This coal is used to produce heat energy which can be used in the heating of water to produce steam. This steam is used to move turbines which turn mechanical energy into electric energy.
