Cell membrane, Nucleus, Cell wall, and axon terminal
The most command material used in photovoltaic solar cells is crystalline silicon.
The lysosome or peroxisome.
active transport
organelle that is used to store material, such as water, food, or enzymes, that are needed by the cell
The positive electrode is a graphite rod (elemental carbon).
Current doesn't flow inside the cell. The cell is used to push current through an external circuit. The so-called "conventional" current flows out of the positive terminal of the cell, through the circuit, and back into the negative terminal of the cell. The confusing truth is that the actual physical carrier of current is the electron, which carries a negative charge. So the things that are actually moving and carrying the current through the circuit leave the dry cell from its negative terminal, physically flow through the circuit, and end up at the cell's positive terminal.

Positive, because the negative terminal is usually used as the ground plane.

A rheostat is simply a variable resistor used to control current. It does not have a positive or a negative terminal.
Vehicle Electrical System GroundingFor MOST automotive electrical systems, NO, the positive battery terminal is NOT the ground. In most vehicular electrical systems the positive terminal is the "HOT" terminal, not the ground.The NEGATIVE TERMINAL IS ESTABLISHED/USED AS GROUND, in almost all vehicles.It is important to note that there are occasionally some exceptions to this standard, and you need to determine which grounding system is used on any vehicle BEFORE messing around with the electrical system.
Silicon
I think it is nothing
The ceramic materials are used for pem menbrane cell.
genetic material is a cell that can be turn into a amino acid to a protein.
Secretion of material out of cell, manufactured materials to be used in other cells.
