Explanation:

The cardiovascular system is vital for life. During the day and during the night, minute by minute, our cells need nutrients and oxygen.

Thanks to a complex and complete system of “pipes”, the heart, as if it were a double pump, is able to propel, through the arteries, the oxygenated blood and the nutrients necessary to give life to all the cells of the body, and in less than a minute.

The blood vessel network, in the form of eight, performs the following functions:

the rapid transport of blood with oxygen and nutrients to human body tissues and organs, as well as the collection of metabolic wastes. It also carries vital substances for body homeostasis.

Hormonal control: it takes hormones to the target organs and secretes its own hormones.

Temperature regulation: controls the distribution of heat between the center of the body and the skin.

Reproduction: helps an erection to occur.

the defense against pathogens: it carries immune cells and antibodies.

the expulsion of substances and salts through the filtrate of the kidney maintaining the pH of the blood and the balance of sodium (salt) and potassium, essential for life.

Qué tipo de anomalía cromosómica es el síndrome de down y Cómo se manifiesta? ¿Qué tipo de anomalía cromosómica es el síndrome d
sashaice [31]

Answer:

El síndrome de Down es el resultado de un niño nacido con un cromosoma adicional agregado al número esperado de cromosomas (generalmente destinado a ser 46).

El síndrome de Angelman se produce cuando un niño nace con una mutación en el 15º cromosoma heredado de los padres.

Explanation:

En el síndrome de Down, se agrega un cromosoma adicional al complemento de cromosomas que un niño debe heredar de sus padres. Se supone que un niño tiene un complemento de 46 cromosomas (23 cada uno) de ambos padres. Una vez que hay un aumento en este número, se establece el síndrome de down. Es una condición cromosómica común. Puede manifestarse como una trisomía, causada por la no disyunción durante la división celular, lo que resulta en 3 copias del cromosoma 21 en lugar de 2 copias, mosaicismo, donde una mezcla de células se clasifican en 2 grupos que contienen un complemento completo de 46 cromosomas y el otro un el cromosoma adicional lo hace 47 y la translocación ocurre cuando un cromosoma 21 adicional o parte del 21 se une al cromosoma 14. Los niños generalmente tienen cabezas y orejas pequeñas, cuellos cortos, caras planas, etc.

En el síndrome de Angelman, el cerebro se ve afectado en gran medida, debido al efecto de la mutación en el sistema nervioso. La pérdida de la función en el 15º cromosoma es responsable del síndrome de Angelman, que resulta en la incapacidad del niño para hablar, mantener el equilibrio, moverse, un desarrollo deficiente tanto física como intelectualmente.

The answer is copper. Nonrenewable resources are those that cannot be readily/naturally replaced at rates that match those of consumption (an aspect that allow renewable resources to be sustainable). Copper are made deep in earth at very slow rates hence do not readily renew themselves. Organisms, on the other hand die, and are naturally replaced by offspring.
