Answer: Incomplete questions. Should include options:
a.8 bolts and 56 nails
b.14 bolts and 44 nails correct answer
c.18 bolts and 32 nails
d.20 bolts and 26 nails
Explanation: Azerbaijan is willing to trade 3 nails to Uzbekistan for every bolt that Uzbekistan makes.
Therefore for every 3 nails produced Azerbaijan gets 1 bolt.
3 nails gives 1 bolt
6 nails gives 2 bolts
9 nails gives 3 bolts
12 nails gives 4 bolts
15 nails gives 5 bolts
18 nails gives 6 bolts
21 nails gives 7 bolts............
42 nails gives 14 bolts.
This is the closest answer.
Answer:
Threshold is a specific voltage that is needed by a neuron to generate action potential
the absolute refractory period is period in which neurons are unable to generate second action potential. And relative refractory period is interval following absolute refractory period.
Normally -70mV voltage is required to stimulate an action potential
Explanation:
The relative refractory period is the period occur shortly after the depolarization of a nerve fiber when partial repolarization has occurred and need a greater stimulus which can stimulate a second action potential.
During an action potential, sodium channels (voltage gated) open, and sodium rushes into the cell because there is more sodium outside the cell than inside and after specific time period sodium channels closed and at the same time potassium channels opens which let the positive ions (potassium ions) to goes out of the cell which makes axon negative and again ready for other action potential
The action potential generates at −70 mV which raised it to threshold potential which is above −55mV then rapidly rises to a peak potential of +40 mV and then the potential drops and overshoots to −90 mV, and the resting potential of −70 mV is reestablished.
