A neuron's ability to generate action potentials depends: Question 1 choices Choice A., on the axon reaching threshold and the o

pening of voltage-gated sodium channels, allowing sodium to enter the axon. Choice B., on the axon reaching threshold and the opening of voltage-gated sodium channels, allowing sodium to leave the axon. Choice C., on the immediate opening of voltage-gated potassium channels once threshold has been reached, allowing potassium to leave the axon. Choice D., on the immediate opening of voltage-gated potassium channels once threshold has been reached, allowing potassium to enter the axon.

Answer is A
Firstly axon must reach the threshold level and then depolarisation occurs. Depolarisation phrase means sodium enters and potassium leaves the axon . Choice C can't be because main idea is the entering of sodium ions.

What heats up the fastest (in order) wet sand, rock, water, dry sand
dedylja [7]
The specific heat capacity represents the amount of energy, in joules, that it takes to raise the temperature of one gram of a given substance by one degree Celsius. Put more simply, the amount of energy it takes to raise a quantity of water by one degree Celsius would raise an equivalent quantity of sand by a little over 14 degrees. Likewise, sand does not need to lose nearly as much energy as water to produce equivalent cooling. Since it "holds" a lot less energy, it cools down much faster than sand.
Indeed, liquid water has an unusually high specific heat capacity. Because it is much less prone to temperature swings than other common substances, large bodies of water often work to moderate temperatures in a region. This helps to explain, for example, why average temperatures fluctuate very little over the year in San Francisco, a city whose climate is heavily influenced by the water that nearly surrounds it.
