¿Cual es la importancia biológica de los estímulos umbrales?

En electrofisiología, el potencial umbral es el nivel crítico al que debe despolarizarse un potencial de membrana para iniciar un potencial de acción.

Explanation:

En neurociencia, los potenciales de umbral son necesarios para regular y propagar la señalización tanto en el sistema nervioso central (SNC) como en el sistema nervioso periférico (SNP).

Espero que esto ayude :))

white blood cells or wbc s are mainly 2 types-

1.agranulocytes

2.granulocytes

the monocytes or macrophages of agranulocytes , dendritic cells which are accessory leucocytes, and b cells which is one type of lymphocytes   identify the antigens present on the pathogen's surface. these three cells are called antigen presenting cells(apc) which are phagocytes and destroy the antigens by secreting antitoxins. besides this leukocyte is always plays vital role in the immunity of the body.

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
