Answers

Answer 1

Answer:

1.) Lactase is an example of ENZYME.

2.)An INHIBITOR is a molecule that can bind to an enzyme and prevent the enzyme from working.

3.)Enzymes speed up chemical reactions by lowering the ACTIVATION ENERGY,

4.) a molecule of SUBSTRATE binds to the enzyme and is broken down into one or more molecules of PRODUCT which are released.

5.) The specific location within an enzyme molecule where the substrate binds is called the ACTIVE SITE.

Explanation:

An enzyme is defined as the substances that aids in the breaking down of complex food substances, taken in by animals, into simple, soluble and diffusible substances before they can be absorbed into the body. In the enzymatic reactions, a molecule of SUBSTRATE binds to the ACTIVE SITE of an enzyme and is broken down into one or more molecules of PRODUCT which are released.

There are different types of enzymes which are named according to the type of good they digest, these include:

--> Lactase: breaks down Lactose

--> proteases: breaks down proteins

--> Amylases: breaks down carbohydrate

Enzymes have the following characteristics:

--> They are proteins

--> They are specific in action. For example Lactase can only act on lactose.

--> They can be inactivated by INHIBITORS.

--> They are sensitive to temperature

--> They speed up a reaction by lowering the ACTIVATION ENERGY

How does bacteria cause disease?

Answers

Answer:

Bacteria cause disease by secreting or excreting toxins (as in botulism), by producing toxins internally, which are released when the bacteria disintegrate (as in typhoid), or by inducing sensitivity to their antigenic properties (as in tuberculosis).

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

Adults produce gametes through a type of cellular reproduction called mitosis. The process of a sperm cell and an egg cell fusing together is called fertilizationand produces a zygote. As a zygote undergoes rapid cell division to develop into an embryo, fetus, and eventually baby, the type of cellular reproduction being used is . As a baby grows into an adult, the type of cellular reproduction used is mitosis.

Answers

Answer:

Mitosis.

Explanation:

Mitosis is the type of cellular reproduction which is used in order to develop an embryo, fetus, and eventually baby. In mitosis type of cell division, the parent and mature cells divides into two daughter cell. This type of cell division occurs in somatic or body cells whereas meiosis type of cell division occurs in the sex cells which produces four daughter cells from a single parent cell.

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

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.
