When two hormones must be present to achieve full expression of an effect, that interaction is called ______________.
Vinvika [58]

Answer:

Synergism

Explanation:

Synergism means cooperation, and is a term of Greek origin (synergy). Synergy is a work or effort to accomplish a certain very complex task, and to be able to succeed in the end. Synergy is the moment when the whole is greater than the sum of its parts.

In physiology, synergism occurs when the effect of two or more combined chemical agents is greater than the sum of individual effects. Concerning hormones, synergism happens when two hormones must be present for the full expression of an effect. That is, two hormones act for a certain purpose.

Example: FSH (follicle stimulating hormone) and estrogen cause oocyte maturation, but this only occurs if neither acts in isolation.

¿Por qué la aparición de la comunicación celular fue un paso clave en la evolución de los organismos multicelulares?
Deffense [45]

Answer:La transición de formas de vida unicelulares a multicelulares ha ocurrido en más de una ocasión a lo largo de la evolución. Las plantas, las algas marrones, los hongos y los animales han adquirido estilos de vida multicelulares de forma independiente y convergente.

La aparición de los animales representó un paso evolutivo clave en la historia de la vida. El desarrollo embrionario y todas las funciones que requiere la vida multicelular se hallan conservados en todos los animales, desde las esponjas a los humanos.

La secuenciación de los genomas de las especies unicelulares más cercanas a los animales ha revelado que estas ya contenían muchos de los genes necesarios para la multicelularidad. Estos habrían sido reutilizados para nuevas funciones multicelulares en el ancestro común de todos los animales.
