The endocrine system involves a number of organs and glands that secrete hormones. The posterior pituitary gland is responsible

for secreting antidiuretic hormone (ADH). When the posterior pituitary gland overproduces ADH, a condition called the syndrome of inappropriate antidiuretic hormone (SIADH) develops. Which characteristics best describe SIADH?

Answer:

The characteristics that best describe SIADH is the ones explains below

Explanation:

(SIADH) or known as syndrome of inappropriate secretion of antidiuretic hormone is a disorder of impaired water excretion caused by the inability to suppress the secretion of antidiuretic hormone.

The characteristics that best describe SIADH is: Fluid retention, serum hypoosmolality, dilutional hyponatremia, and concentrated urine with normal intravascular volume .

The process where maiten magma rises and sinks due to tempature of difference, CRIVNCONEO
SIZIF [17.4K]

Answer:

Convection

Explanation:

The process where molten magma rises and sinks due to the temperature difference is known as CONVECTION.

This occurs when the hot magma moves upward and is cooled and moves downward again to be heated due to temperature difference, and similarly when cold magma moves upward and is heated and moves downward again to be cooled due to temperature difference.

Hence, in this case, the correct answer is CONVECTION

¿Cual de los siguientes solutos que pueden estar presentes en el liquido extracelular es transportado de acuerdo al modelo de me
kolezko [41]

Complete question:

¿Cual de los siguientes solutos que pueden estar presentes en el liquido extracelular es transportado de acuerdo al modelo de mecanismo propuesto en la ilustracion?

A) Etanol.

B) Calcio.

C) Glucosa.

D) Estrógeno.

E) Oxígeno.

<em>Nota: La ilustración se encuentra como un archivo adjunto.</em>

Answer:

Ión Calcio y Estrógeno son transportados por proteinas canal a traves de la membrana.      

Explanation:

Durante el paso de sustancias al interior o exterior de la celula ocurren dos tipos de transportes. Transporte activo y pasivo. El primero requiere de energia ya que se produce en contra de un gradiente electroquímico. El segundo, por otra parte, no requiere de energía ya que sucede a favor del gradiente electroquimico.

  • El transporte activo es mediado por proteinas transportadoras que actúan como bombas transportadoras.
  • El transporte pasivo puede ocurrir por
  1. difusión simple a traves de la bicapa lipídica (sin ningunaproteina que medie su paso),
  2. difusión facilitada a traves de proteinas canales (estas proteinas tienen forma de poro hidrofílico y permiten el paso de sustancias de un lado al otro de la membrana celular sin sufrir modificaciones. Permiten el pasaje de iones actuando como canales ionicos y de hormonas o neurotransmisores),  
  3. o difusión facilitada a través de proteinas transportadoras o carriers (estas proteinas son altamente selectivas y sufren un cambio temporal en su conformación al hacer pasar una sustancia de un lado al otro de la membrana plasmatica).    

<em>La ilustración adjuntada muestra un ejemplo de </em><em>proteina de canal</em><em> facilitando el transporte de distintas sustancias.</em>

A) Etanol.  Transporte pasivo. Difusión simple a traves de la bicapa lipídica.    

B) Ion Calcio, Ca²⁺.  Transporte pasivo. Difusión facilitada a traves de proteina canal.

C) Glucosa.  Transporte pasivo. Difusión facilitada a traves de proteina transportadora o carrier.

D) Estrógeno.  Transporte pasivo. Difusión facilitada a traves de proteina canal.

E) Oxígeno. Transporte pasivo. Difusión simple a traves de la bicapa lipídica.

In a certain population of red squirrele, a mutation causes several squirrels to
mihalych1998 [28]

Answer:

in a certain population of red squirrele, a mutation causes several squirrels to

be bom with darker coats. These coats make the squirrels nearly inweible

when they are foraging on the forest floor , According to the theory of evolution by natural selection, what is likely to  happen to this trait after several generations?

After several generations, this trait is likely to be much more  common because individuals with the trait will have a greater  chance of passing it on to their offspring,

Explanation:

It would later turn to what is termed as germline mutation which are mutations passed from parent to offspring, as time progresses the trait would be more and increases the chance of being transferred to their offspring
