Answer:The world population increased from 1 billion in 1800 to 7.7 billion today. The world population growth rate declined from 2.2% per year 50 years ago to 1.05% per year. Other relevant research: ... We show how the world population grew over the last several thousand years and we explain what has been driving this change.

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.

FrozenT [24]

Domain of a function is the type of parameters it takes as input. The domain of a sine function is angle in either degrees or radians. The function that represents the population growth of the bacteria that is tripling every minute is given by the mathematical expression,

x_{t} = x_{0} \times 3^{t},

where, t is time in minutes, x_{0} is the initial population size, and x_{t} is the population at time, t.

The domain of this function will be time, t.
