Usted cuenta con 45,2 nM de una sustancia X liofilizada (nota: la liofilización es un proceso de secado de compuestos orgánicos que los lleva a polvo) y necesita preparar con ella una solución stock de 100 µM ¿Que volumen de agua destilada debe agregar al liofilizado?

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.

there really is life in the deepest part

answer:

sequence 1- deletion

                  2- duplication

                  3- insertion

                  4- substitute

                  5- inversion

i think the answer is g1
