Answer:

Autoregulation

Explanation:

When the activities of a cell, tissue, organ, or system change automatically due to environmental variation, the homeostatic mechanism that operates is called autoregulation.

Autoregulation is a method of controlling the local blood circulation. It is characterized as an organ's inherent capacity to sustain a standard blood flow, given changes in the pressure of the perfusion.

<span>The trick here is to understand the definition of each of the cellular transport or function mechanisms listed. These are some interesting (and strange) analogies!

Facilitated Diffusion
This is when a mechanism assists in diffusing (spreading) some material into an environment. The dog on the wagon going through a spring loaded door would shoot it out into the environment. This is an odd analogy but Point 3 would be the one.

Active Transport 
Is when energy is expended to transport molecules somewhere against a concentration gradient or some other barrier. Examples include transporting molecules across a cell wall. The best analogy is the dog being dragged into a bathtub (Point 1).

Phagocytosis 
This is when a larger cell consumes a molecule often like eating. This matches to point 2 - the child eating the doughnut.

Passive Diffusion
Is when a concentration of molecules naturally diffuse into an environment. This suits point 5 - the crowded room full of people.

Pinocytosis
Is the budding of cell membranes to consume liquid in the surrounding environment. I guess a woman drinking tea is the closest analogy listed (Point 4).</span>

Degger [83]

Answer:

Answer is A. B-hemoglobin mRNA is translated more efficiently than is a-hemoglobin mRNA.

Explanation:

The introduction of electric charge into a gel or fluid, causing or resulting in the movement of the charged particles in the gel or fluid, is referred to as the electrophoresis. It can also be explained as a separation method or technique which is based on the movement of particles or ions in an electric field.

The electrophoresis is used in separating DNA fragments , RNA or protein, based on their size and charge.

Beneficios y desventajas de la modificación genetica
finlep [7]
La manipulación genética representa todas aquellas técnicas que permiten modificar de forma directa los genes en el interior de las células de los organismos vivos. Estas modificaciones pueden ser a través de la inserción, la eliminación o la alteración de uno o más genes específicos. Todas las instrucciones que hacen que un organismo sea lo que es están codificadas en los genes, es decir que estos fragmentos de ADN son los que le indican a cada parte de las células y a cada célula en el cuerpo de un organismo multicelular o unicelular, qué debe hacer, cuándo y cómo. La manipulación genética es uno de los procesos científicos biotecnológicos más empleados hoy en día, ya que incluye todas las herramientas necesarias para modificar las características físicas de prácticamente cualquier ser vivo o, mejor dicho, de todo lo que tenga información genética en su interior (ADN o ARN).

Hoy en día la manipulación genética es uno de los temas más discutidos por la sociedad científica, pues existen herramientas biotecnológicas capaces de manipular de manera fácil y efectiva casi cualquier gen que se desee en un organismo Entre los organismos que se pueden “manipular genéticamente” se incluye al ser humano, y es allí donde surgen la mayoría de los debates, ya que a pesar de que la manipulación genética puede ayudar a curar un gran número de enfermedades hereditarias, también puede utilizarse para crear armas biológicas sumamente peligrosas.

How are the three chromosomal aberrations differend from each other?
Lorico [155]
The three chromosomal aberration: 

1.) Inversion - breakage of chromosome in two places , the other piece of DNA is re- inserted into the chromosome.
2.) Translocation - the one piece breaks off and attaches to another chromosome. 
3.) Deletion - the loss of segment of chromosome.
