is Earth an open system or closed system? Explain your answer and provide at least one example that occurred during the Precambr
Ivan

Answer:

The Earth is essentially a closed system; it obtains lots of energy from the Sun but the exchange of matter with the outside is almost zero. Isolated systems can exchange neither energy nor matter with an outside system.

The Precambrian was originally defined as the era that predated the emergence of life in the Cambrian Period. It is now known, however, that life on Earth began by the early Archean and that fossilized organisms became more and more abundant throughout Precambrian time.

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.

Which type of asexual reproduction involves duplication of the parent DNA before dividing itself into two?
Kipish [7]

Answer:

binary fission - asexual reproduction by a separation of the body into two new bodies. In the process of binary fission, an organism duplicates its genetic material, or deoxyribonucleic acid (DNA), and then divides into two parts (cytokinesis), with each new organism receiving one copy of DNA.
