no... it is made up of elements. It does not have cells because it is an element. Think of hydrogen. Its an element.

Which particles-starch or Lugol's-were able to cross the model cell membrane?
The particles that were able to cross the model cell membrane was the Lugol's solution.
What is it when ions are in a low concentration outside a cell and they slowly cross the membrane into the cell?
the answer is the membrane are probably broken down
How does CO2 cross the cell membrane?
No, carbon dioxide does not need a transport protein to cross the cell membrane. It can pass through a membrane by diffusion.
What allows water to cross the permeable membrane of an animal cell?
plasma membrane allows water to enter animal cell
Why is a cell membrane called semi-permeable or selectively permeable?
As the cell membrane only allows certain substances to enter or leave the cell, meaning that while it IS permeable (as some substances can cross it), it is only selectively as not all substances are able to cross it, only some.
What ions are positively charged and can cross back and forth across neuron and cell membrane?
There are two ions that can cross the cell membrane. The positively charged sodium and potassium ions can cross back and forth across the neuron cell membrane.
Which particles-starch or Lugol's-were able to cross the model cell membrane?
The particles that were able to cross the model cell membrane was the Lugol's solution.
What is a calcium ion receptor?
This is a protein on or embedded in a cell membrane that activates when a Calcium ion interacts with it.
What depends on a molecule that can cross the plasma membrane?
The Gonhiqule depends on a molecule and cross the plasma membrane in an animal cell, but is a different story for the plant cell because of the cell wall.
What kinda ions are positively charged and can cross back and forth across the neuron cell membrane?
There are two ions that can cross the cell membrane. The positively charged sodium and potassium ions can cross back and forth across the neuron cell membrane.
What is cell membrane permeability?
It is the ability of the membrane to allow ions and/or particles to cross.
What is it when ions are in a low concentration outside a cell and they slowly cross the membrane into the cell?
the answer is the membrane are probably broken down
How does CO2 cross the cell membrane?
No, carbon dioxide does not need a transport protein to cross the cell membrane. It can pass through a membrane by diffusion.
What vitamin promotes the formation of the cell membrane?
vitamin E
What receptor has a ligand that can cross the cell membrane that binds?
Intracellular
Which transport is used to move calcium in or out of the cell?
Calcium is primarily transported into or out of the cell using specialized protein channels called calcium channels. These channels allow calcium ions to move across the cell membrane, either into the cell (via calcium influx) or out of the cell (via calcium efflux). Additionally, calcium can also be transported into the cell by calcium transporters such as ATPase pumps.
What restores and puts the cell membrane to resting conditions after an action potential?
Calcium
