Molecules moving from an area of greater concentration to an area of lesser concentration is called: 
	A.	osmosis
	B.	diffusion
	C.	concentration
	D.	none of the above

anonymous · Answer

How about "not math"?

(it's diffusion)

What type of molecular transport is able to move molecules from low concentration to high concentration areas?
	A.	Active transport
	B.	Diffusion
	C.	Osmosis
	D.	Passive transport

e.cociuba · Answer

A.)

e.cociuba · Answer

That would be active transport. Diffusion is the same as passive transport meaning that molecules move from areas of high concentration to areas of low concentration.

anonymous · Answer

Passive transport does not necessarily need to be diffusion, it's a broader category.

e.cociuba · Answer

ok macho man lol jk :P

anonymous · Answer

Moving against a concentration gradient, however, indeed requires additional energy, which is how active transport works.

anonymous · Answer

lol so which one would it be lol?

e.cociuba · Answer

Active Transport rite? @oldrin.bataku

anonymous · Answer

Moving against the concentration gradient is acting against entropy so indeed it is active transport.

e.cociuba · Answer

Perfect! :)

Which of the following shows the correct level of organization in multicellular organisms from simplest to most complex? 
	A.	cell, organ, tissue, organ system.
	B.	cell, tissue, organ, organ system.
	C.	organ system, tissue, organ, cell.

What is equilibrium?
	A.	A group of different tissues that work together to perform a specific function
	B.	A special type of diffusion that occurs with water molecules
	C.	Small, round organelles that break down large food particles into smaller ones
	D.	The balance between the concentrations inside and outside a cell

anonymous · Answer

Diffusive equilibrium is where there is no concentration gradient, in isotonic environments i.e. where there is a *balance* of concentrations on either side of the cell membrane.

anonymous · Answer

So what would our answer be?
