padilas [110]

In a resting state, sodium (Na ) is at a higher concentration outside the cell, and potassium (K ) is more concentrated inside the cell. During an action potential, the sodium levels <u>increase </u>inside the cell.

During an action potential, the potassium level inside the cell decreases, and the sodium level inside the cell increases. That is to say, there is an outflow of potassium and an inflow of sodium ions.

Action potential usually occurs when an electrical signal disrupts the balance of Na+ and K+ within a cell membrane, briefly depolarizing the concentrations of each.

malfutka [58]
Lll. a limited supply of necessary resources. If there isn't enough resources the species will have to learn to adapt to be able to gather the new food supply they need. Such as birds and there beaks, if the insects population went down and that was the main food supply for that type of bird they would have to be able to adapt in order to survive, so evolution occurs. Over time that bird would change to adapt to its new feeding source.

Hope this helps!

A roller coaster train with a mass of 500 kg stops at the top of a hill. If the hill is 110 m high, what is the potential energy
katrin [286]
Potential energy=PE
PE=mgh
m=mass in kilograms.
g=9.8 m/s
h=height in meters

Data:
mass=500 Kg
h=110 m

PE=(500 Kg)(9.8 m/s²)(110 m)=539000 joules
