SOVA2 [1]

Answer:

la selección natural es el mecanismo principal por el cual la evolución ocurre

Explanation:

Charles Darwin fue un naturalista inglés que propuso la teoría de la evolución o 'descendencia con modificación' mediante el mecanismo de selección natural. Acorde a esta teoría, la selección natural se define como el mecanismo selectivo de reproducción diferencial de los individuos mejor adaptados a su ambiente. La variabilidad es el la materia prima sobre la cual la selección natural actúa, seleccionado aquellos individuos que presentan combinaciones fenotípicas y genotípicas más adaptadas para sobrevivir en un ambiente en particular. Los individuos de una población que son 'superiores adaptativamente' poseen más chances de sobrevivir y reproducirse, y por lo tanto tienen también más probabilidades de transmitir sus genes a la siguiente generación.

Ksju [112]

Answer:

<u>They produce the materials needed by the sperm to travel to the egg</u>

Explanation:

Seminal vesicles are glands located near the distal end of the vas deferens. They are responsible mainly for the secretion of seminal fluid as the sperm are moved along towards the ejaculatory duct. The seminal fluid contains a substance which stimulates the sperms. The seminal fluid also contains simple sugars e.g. fructose which provide nourishment for the sperms.
