The spontaneous action potential established in cardiac contractile cells is highly dependent on which of the following? A. The
Arada [10]

Answer:

E. All of the above

Explanation:

In cardiac contractile cells there is rapid depolarization, then a plateau phase and repolarization.

when an action potential stimulates the cell, voltage-gated channels open quickly commencing the positive-feedback mechanism of depolarization. This in turn raises the membrane potential to approximately +30 mV, and this closes the sodium channels. Next comes the plateau phase, where membrane potential declines relatively slowly due to the opening of the slow Ca2+ channels, allowing Ca2+ to enter the cell while few K+ channels are open, leading to K+ to exit. Once the membrane potential reaches approximately zero, the Ca2+ channels close and K+ channels open, allowing the exit of K+. The repolarization lasts approximately for a while and here is when the membrane potential drops until it reaches resting levels once more and repeats the cycle.

denpristay [2]

Answer:

Dark matter provides the gravity that allows the stars to rotate at the same speed.

Explanation:

The stars at the edges of a galaxy are rotating around the galaxy’s center at the same speed as the stars in the middle of the galaxy. How does this provide evidence of dark matter?

Dark matter absorbs light from outside the galaxy, allowing the light of the stars in the galaxy to show the orbital speeds of the stars.

Dark matter emits the light that astronomers need to see the orbital speeds of the stars.

Dark matter subtracts gravity, which allows the stars to rotate at the same speed.

Dark matter provides the gravity that allows the stars to rotate at the same speed.
