Ou just read an article on the Endosymbiotic Theory. Based on what you read, what is the importance of the Endosymbiotic Theory?
VikaD [51]

Answer: The endosymbiotic theory suggests that eukaryotic organisms evolve from primitive prokaryotic organisms.

Explanation:

According to the endosymbiotic theory the organelles like mitochondria and chloroplast in the eukaryotic cells have arisen from aerobic bacteria. The aerobic bacteria being prokaryotic cell was consumed by the anaerobic bacteria or prokaryotic cell.

The following are the evidences of the origin of eukaryotic organisms from prokaryotic organisms:

1. The chloroplast and mitochondria have circular DNA like bacteria.

2. The mitochondria and chloroplast reproduce through binary fission which also occurs in bacteria.

Blababa [14]

Answer:

a. Uninucleate, nonstriated

Explanation:

Smooth muscle tissue is composed of smooth muscle cells that are spindle-shaped with a single nucleus. Smooth muscles line the walls of hollow organs such as urinary bladder, uterus, stomach, intestines but also arteries and veins and the tracts of the respiratory, and reproductive systems.

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.
