Extracting aluminum from ore takes 20 times more _____ than obtaining it from _____ sources
mamaluj [8]
Extracting aluminum from bauxite ore requires 20 times more energy than extracting it from aluminum from recycled sources so therefore that is a good reason to promote its recycling starting with pop and beer cans which are things that most of us use.

What evidence must be considered when determining whether or not a trait is an adaptation? (Site 1)
Alexeev081 [22]
According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation. The next generation will have the things they will need to survive and the longer the generation goes the more fetchers they will have.

Si se aparean especies diferentes como por ejemplo el cruce entre caballos y burros; podemos afirmar que si llegan a tener desce
White raven [17]

Answer:

El híbrido va a ser esteril.

Explanation:

En la cruza entre dos especies distintas, cuando ocurre, existen distintos mecanismos de aislamiento reproductivo, que son barreras que inhiben o interrumpen el flujo génico entre especies distintas. Es decir que no habrá exito reproductivo de estas cruzas. Se trata de caracteres biológicos propios de cada especie que previenen la reproducción con otras especies.

Estos mecanismos de aislamiento reproductivo pueden ser precigóticos o postcigóticos.  

  1.Pre-copulatorios o pre-cigóticos:

  • Ecológico o por aislamiento de hábitat;
  • Estacional o temporal;
  • Sexual o etológico;
  • Mecánico;
  • Por incompatibilidad de gametas.  

  2. Post-copulatorios o cigóticos:

  • Inviabilidad del híbrido;
  • Esterilidad del híbrido;
  • Híbrido con viabilidad o fertilidad disminuido;
  • Interacciones citoplasmáticas.

La mula es producto de la cruza entre dos especies distintas: una yegua (Equus ferus caballus) y un burro (Equus africanus asinus). Es un ejemplo de la accion de mecanismo poscigótico, en el cual se forma un híbrido viable esteril. Este ejemplar puede nacer, crecer y sobrevivir, pero que no puede producir gametas funcionales, por lo cual no puede reproducirse.
