Definitions? ? ? i need these for biology before 10-18-17 and i'm desparate for answers !

Active Transport- movement of materials across a membrane that requires an input of energy from a cell.  
Passive Transport- movement of materials across a membrane that does not require energy from the cell
Diffusion- process in which atoms and molecules move from an area where they are more concentrated to an area where they are less concentrated.
Endocytosis- the movement of materials into a cell by use of a vesicle.
Exocytosis- the movement of materials out of a cell by use of a vesicle
Facilitated Diffusion-the process of spontaneous passive transport 
Homeostasis- the tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes
Hypertonic-having a higher osmotic pressure than a particular fluid, typically a body fluid or intracellular fluid.
Hypotonic-having a lower osmotic pressure than a particular fluid, typically a body fluid or intracellular fluid.
Isotonic- denoting or relating to a solution having the same osmotic pressure as some other solution, especially one in a cell or a body fluid.
Osmosis- the diffusion of water through a membrane that is selectively permeable to the water more than other molecules
Permeable- allowing liquids or gases to pass through it.

It feels feed the echo system

Aneutral atom must have the same number of neutrons and protons? no, they must have the same number of protons and electrons
