The passive transport used by water molecules to move across a cell membrane is called Osmosis.

In the case of water molecules, they do not require any specialized help to cross the cell membrane, for this reason, option B which indicates diffusion through the help of carrier proteins, is false. Option C is false as well given that Endocytosis is a form of active transport.

The remaining options are Diffusion and Osmosis. Though very similar, there is one key difference between the two. Diffusion occurs when particles move from a place of higher concentration to a lower concentration point, in order to achieve equilibrium.

The difference from Osmosis is that in Osmosis, the solvent particles can move without the need for other particles to move. This is the case for the small water molecules and because of this, the correct option is A.

If there is no lactose present, how does bacteria respond? The gene for beta-galactosidase turns on. The gene for beta-galactosi
mojhsa [17]

Answer:

The gene for beta-galactosidase turns off.

Explanation:

The gene that codifies the beta-galactosidase enzyme is part of the <em>lac</em> operon, which also contains two other genes that produce enzymes involved in the metabolization of lactose.

Between glucose and lactose, the bacteria will preferentially use glucose as an energy source. On the other hand, lactose is a dimer, and thus a series of enzymes are needed to process lactose before its use as an energy source.

If there is no lactose present, the genes contained inside this operon are turned off (the operon is repressed).

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.
