Tina is studying chipmunks in a field of 900 square meters. In 2020, she counts 194 chipmunks. In 2021, she counts 231 chipmunks

. What is the population density of chipmunks in 2021?

Answer:the population density of chipmunks in 2021=256,666.667 per square kilometres

Explanation:

Population density is defined as the number of population per unit area of land

which can be expressed as

Population density =number of population/ land area

Since  land area is usually given in square kilometres or square miles  we convert 900 square meters to square kilometres

1 square kilometres =1000000 square meters

900 square meters=900/1000000=0.0009 square kilometres

Therefore, the population density of chipmunks in 2021= 231/0.0009 square kilometres =256,666.667 per square kilometres

How do the vacuoles and cytoplasm contribute to maintaining homeostasis in a cell?
Anestetic [448]

Answer:

Vacuoles regulate the turgidity by regulating the amount of water inside the cell. cell has excessive water: vacuole absorbs the water and then diffuses it out of the cell. cell lacks water: water from the vacuole gets passed back into the cell thereby maintaining turgidity

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.
