Cell Potential

A blood cell is placed into the jar, as seen. Where will the water go?

• Into the cell

• Out of the cell

• Equally in & out - it's isotonic

• The water is a lie

A membrane potential becoming less negative is called

• hyperpolarization

• depolarization

• repolarization

• polarization

If the graded stimuli are of the right kind (usually a neurotransmitter), duration and strength, they can have an ​ (a)   effect, resulting in a ​ (b)   stimulus. This will cause ​ (c)   to flow in long enough to change the potential to ​ (d)   mV, the threshold ​ (e)   .

• threshold

• subthreshold

• Na+

• -55

• -70

• K+

What number(s) on the graph represents the Resting Potential?

• 1 and 2

• 1 and 5

• 2 and 3

• 3 and 4

• 0.64 net flow of water out of the cell

• -0.36 net flow of water into the cell

• 8.17 net flow of water out of the cell

• -8.83 net flow of water into the cell

Where will the water go?

• Into the cell

• Out of the cell

• Equally in & out - it's isotonic

• There is no water

In a turgid plant cell, which describes pressure potential of cell water
