The answer is C Nuclear Regulatory Commission
Answer:
El enlace iónico se da entre dos átomos diferentes (metálico y no. metálico), mientras que el enlace covalente se produce entre dos átomos iguales (no-metálicos). En el enlace covalente hay un compartimiento de electrones, mientras que en el enlace iónico hay una transferencia de electrones
Explanation:
Answer:
The correct answer is
B.action potential; sodium
Explanation:
Action potential
Nerve action potentials are initiated and propagated in an all or nothing fashion. The all-or nothing action potential is initiated when the membrane potential threshold value is reached
Sodium
Voltage-gated Na⁺ ions membrane channels open enabling an influx of sodium ions to rapidly enter the cell, raising the membrane potential up to +40 mV
Depolarization in the neuron is based ion exchange channels opening to allow the rapid influx of sodium ions (Na⁺) and the efflux of potassium ions (K⁺)
The neuronal responds rapidly and for short periods to the activation of an ion channel receptor by a drug or natural neurotransmitter is rapid rel
Chlorine is element number 17, so the electron configuration must be:
2,8,7
