Chemistry
1 answer:
aleksklad [387]4 years ago
5 0

Explanation:

Fire is the visible light given off during combustion. It is usually a product of the rapid oxidation of substance in the presence of heat.

Fires have a broad range of applications and their disadvantages abound too.

The elements of fire are:

  • Fuel: every fire must have a fuel. Almost everything is combustible and can serve as fuel. The fuel is the material that combines with oxygen.
  • Oxygen; the oxygen provides the oxidation for the fuel. This sets it alight.
  • Heat: heat is needed to start a fire. This initiates and drive the reaction.

Fire is a product of combustion reaction and it occurs in the presence of oxygen gas.

"The occurrence of the all-or-none ________________ results from depolarization in response to rapid entry of ____________ ions
Leno4ka [110]

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
