HELP ME!!!!!!PLEASE

the choices are
A.they flow from outside the cell in
B.they flow from inside the cell out
C.they flow from the inside of one cell into the next cell
D.Calcium ions cant flow in or out of the cell

Answer 1

.they flow from inside the cell out

Step-by-step explanation:

Calcium ions move naturally through diffusion from a region of high concentration to a region of low concentration. Due to the concentration gradient between the inside and the outside, the ions will move from the inside to the outside until an equilibrium is reached.
