I DONT KNOW IM TRYING TO ASK YOU THIS!
What else can I help you with?
When materials move passively by diffusion in what dirction do they go through the cell?
Materials move passively by diffusion from an area of higher concentration to an area of lower concentration, across the cell membrane. This process allows the substances to reach equilibrium within the cell.
Diffusion allows materials to?
Diffusion allows materials to move from an area of high concentration to an area of low concentration until equilibrium is reached. This process occurs passively, driven by the random movement of particles.
In passive transport materials move from an area of higher concentration to an area of lower concentration through a cell membrane.?
yes
When materials need to move into a cell but require no energy to enter it is called?
When materials move into a cell without requiring energy, it is called passive transport. This process relies on the concentration gradient, allowing substances to move from an area of higher concentration to one of lower concentration. Examples of passive transport include diffusion and osmosis.
Why is it easier to move materials across membranes down a concentration gradient?
osmotic pressure

yes
How do materials move in and out of a cell?
they usually don't.
Why is it easier to move materials across membranes down a concentration gradient?
osmotic pressure
How does fat move in the molecules?
Molecules usually move from high concentration to lower concentrations. East-side
In materials move from an area of higher concentration to an area of lower concentration through a cell membrane.?
Through the process of mitosis.
How molecules moved?
Molecules usually move from high concentration to lower concentrations.
What is required when cells must move materials against a concentration gradient?
Active transport which requires ATP.
How do transport proteins that are pumps differ from that are channels?
Transport proteins that are pumps differ from those that are channels in that when it pumps, it moves materials against concentration gradient. Other wise, from low to high concentration levels. Channels move materials down a concentration gradient, requiring no energy expenditure by the cell. From high concentration to low concentration levels.

What is the name of cellular process in which materials are moved across a membrane from an area of low concentration to an area of high concentration?
active transport
