One way that I would really describe these kind of mirrors would be like first, these kind of mirrors are for sure <span>virtual, upright, smaller. And this would be only due mainly because this the kind of mirror this would be. So based from my information. So based from your options, the answer would most likely be one of the options that would practically fit this. This would be known to be "</span><span> upright and smaller than object".</span>
Answer:
-Reversal of the resting potential due to influx of sodium ions
-Mechanism that restores the resting membrane voltage and intracellular ionic concentrations
-Period during which potassium ions are diffusing out of the neuron because of a change in membrane permeability
-A brief reversal of membrane potential that travels along the axon
Explanation:
An action potential is a situation where the membrane potential is briefly reversed from -70mV to +30 mV
There are three steps of the moving action potential, including;
1) The depolarization step, where the membrane resting potential is reversed by the rush of sodium ions into a neuron
2) The repolarization, due to the closing of the voltage-gated sodium channels and the opening of the potassium channels, which is a mechanism that restores the membrane's resting voltage and the ionic concentration in the cell
3) Hyperpolarization, where due to some open potassium channels, there is an increased potassium permeability, and excessive efflux of potassium ions take place, which results in a dip in the membrane potential
4) The above three phases describe the phase of the action potential which is the brief reversal of membrane potential that travels along the axon
<span>a homogeneous, noncrystalline substance consisting of large molecules or ultramicroscopic particles of one substance dispersed through a second substance. Colloids include gels, sols, and emulsions; the particles do not settle and cannot be separated out by ordinary filtering or centrifuging like those in a suspension</span>
Answer:
1.01 V
Explanation:
From Nernst equation;
Ecell= E°cell- 0.0592/n log Q
Where;
Ecell= observed emf of the cell
E°cell= standard emf of the cell
n= number of moles of electrons transferred
Q= reaction quotient
Q= [Ag^+]^3/[MnO4^-] [H^+]^4
Q= [0.01]^3/[1.20] [1.50]^4
Q= 1.65×10^-7
Ecell= 0.88 - 0.0592/3 log 1.65×10^-7
Ecell= 0.88 - [0.0197×(-6.78)]
Ecell= 0.88 + 0.134
Ecell= 1.01 V
