Question

WHAT IS ALL YOU KNOW ABOUT CHEMICAL COMPOUNDS AND MOLECULES AND OSMOSIS AND DIFFUSION AND ACTIVE TRANSPORT COME ON PPLS I KNOW AMERICA CANT BE THAT STUPID

Answer 1

Geeze, man, I don't think your hard drive is big enough to hold all of that information. Maybe try limiting your topic a little, such as "everything we know about a Carbon-Carbon single bond" which would likely fill several volumes in and of itself.

Answer 2

If you want people to answer your question you might want to try not insulting them, especially when you don't know the answer yourself.

That said, here are some definitions:

active transport is the movement of a substance across a biological membrane against its concentration or electrochemical gradient with the help of energy input and specific transport proteins.

diffusion is the spontaneous tendency of a substance to move down its concentration gradient from a more concentrated to a less concentrated area.

osmosis is the diffusion of water across a selectively permeable membrane.

a chemical compound is a chemical substance consisting of two or more different chemically bonded chemical elements, with a fixed ratio determining the composition.

a molecule is the smallest particle of a substance that retains the chemical and physical properties of the substance and is composed of two or more atoms covalently bonded together.

Answer 3

osmosis:the diffusion of water across a cell

diffusion:the movement of particles from an area where their concentration is high to an area where their is low

active transport:the movement of particles through proteins in the cellmembrane aginst the direction of diffusion
