Sodium and potassium ions move in and out of the axon when the membrane is ______
Ostrovityanka [42]

Answer:

Answer : Depolarized

Explanation:

Sodium and Potassium ions tend to move inside of the axin when the membrane is depolarized.

A change in polarity occurs in the axon membrane when a nerve impulse travels across it.  At the beginning of an action potential or nerve impulse , the ions of sodium tend to move inside of axon causing depolarization. As a result potassium ions tend to move outside of the axon causing re polarization. Hence, this effect causes the nerve impulse to travel in one direction only inside the axon.

Scorpion4ik [409]

Answer:

Drought is 19%

Flooding is 9%

Freeze is 2%

Severe storm is 15%

Tropical cyclone is 48%

Wildfire is 3%

Winter storm is 4%

Explanation:

220 + 108 + 25 + 178 + 550 +31 + 41 = 1153

Basically, you take the number of each natural disaster plus it all together. That is your total.

You then take individually the number and divide it by the total (1153), once you get a decimal number you times it by 100. Which give you the percent

You then do this for the rest of the other natural disasters.

Hoped this helped!
