Answer: Troposphere
Explanation: The troposphere is the lowest layer of the atmosphere. This is the layer where we live and where the weather happens. The Temperature in this layer generally decreases with height. The boundary between the stratosphere and the troposphere is called the tropopause..
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.
Answer:
5.When the skater has high PE it the skater is slow, when the skater has low PE it's going fast. When the skater has high KE the skater is going fast, when it has low KE he's going slow
6. If you double the speed of an object, the kinetic energy increases by four times.If you double the mass of an object, you double the kinetic energy. potential energy increases as weight and height increases
7.The skater won't stop untill he runs out of kenetic energy.It depends on the potential energy to detemines how far it will go.What would slow you down is if the track was long,so eventually it would were out the energy
