Potassium diffuses into the cell
There is a greater concentration of Na plus outside and there is a greater concentration of K plus inside the cell. When the stimulus is delivered, the permeability of the membrane is changed, and Na plus diffuses into the cell, initiating the depolarization of the membrane.
The speed of light (and all other forms of electromagnetic radiation) in vacuum is determined bythe electrostatic permittivity (ε0) and magnetic permeability (μ0) of free space.An interesting thought ... we have no way of knowing whether these physical constants are the samenumbers today that they have always been. If either of them has changed since the birth of the universe,then the speed of light changed, and our observations of the earliest cosmos give an erroneous numberfor the age of the universe.But anyway, that's what these quantities are today, and they're what determines the speed of light,as is so neatly predicted by Maxwell's equations and verified spot-on by the best measurements.
Both "is changed" and "has changed" can be correct depending on the context. "Is changed" is typically used when referring to the current state of something, while "has changed" is used when talking about a change that occurred in the past with a connection to the present.
yes it is changed
An object that is changed and can be changed back like silly putty. Chemical change is when an object is changed and cannot be changed back. ex. egg cracking

The cell membrane is the first part of a cell that is affected by changes in pH. A significant change in pH can alter the structure and function of the cell membrane, leading to disruptions in transport processes and cell signaling.
Osmosis is a physical process, not a chemical change. It involves the movement of solvent molecules from an area of higher concentration to an area of lower concentration across a semi-permeable membrane. No new substances are formed during osmosis.
The potato strips changed length during osmosis because water molecules moved across the semi-permeable membrane from an area of higher water concentration to an area of lower water concentration. This caused the cells in the potato strips to either gain or lose water, leading to changes in their size and length.

it changed by... well it changed... It just changed!
a changed variable is something that you have changed
a changed variable is something that you have changed
They have changed brick work and changed windows
no lens is changed!

It means she changed you. Or you changed your self.
