zubka84 [21]3 years ago
8 0

Answer:

The structure of ATP will need to be used.

Explanation:

Adenosine triphosphate or ATP is an energy rich compound which undergo hydrolysis in presence of water to generate free energy.

         When a molecule is moving against its concentration gradient it requires the input of energy which is generally supplied by the hydrolysis of ATP molecules.

For example Na+K+ATPase uses the energy derived from ATP hydrolysis to transport Na+ inside the cell and K+ outside the cell.

Que tipo de aislamiento reproductivo exhibe la mula?
bulgar [2K]

Answer:

<em>Aislamiento postreproductivo: Esterilidad del híbrido</em>

Explanation:

El concepto biológico de <u>especie</u>, en su definición, destaca que los ejemplares de una especie no pueden entrecruzarse con ejemplares de otra especie distinta, o bien, en caso de hacerlo, no hay éxito reproductivo.

Existen distintos mecanismos de aislamiento reproductivo, que son barreras que inhiben o interrumpen el flujo génico entre especies distintas. 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 (<em>Equus ferus caballus</em>) y un burro (<em>Equus africanus asinus</em>). 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 pueden producir gametas funcionales, por lo cual no pueden reproducirse.

what is the function of vesicles in the synthesis of proteins and the release or those proteins outside the cell?
Zina [86]

Vesicles transport newly synthesized proteins to the Golgi apparatus. After the Golgi apparatus modifies the proteins, vesicles transport the modified proteins to the cell membrane, where they are released.
