lianna [129]
The median is 12.6.



Explanation:

To find the median you list them from greatest to least then whatever number is in the middle is your median.


11.8, 11.9, 11.9, 12.2, 12.3, 12.9, 13.3, 13.4, 13.6, 13.7

So the middle two numbers are 12.9 and 12.3 so you would find the average by adding them together and dividing by 2.

12.3+12.9=25.2
25.2/2=12.6

Describe the change which will occur if a piece of peeled potato is placed in a concentrated sugar solution and explain why this
skelet666 [1.2K]

Answer:

Through the process of Osmosis, water will move from a region of high water potential ('concentration') to low water potential. Therefore, water will slowly leave the cells of the potato and enter the sugar solution in an attempt to reach equilibrium and the potato will therefore lose mass.

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.
