What influences diffusion?
Diffusion is a type of passive transport. The factors that influence diffusion include: concentration gradient, size of molecule involved, distance the molecule has to travel, temperature, solubility of the molecule and surface area.
How is the active transport different from diffusion?
The main difference is that diffusion does not require energy and active transport does require energy. Just for the record diffusion has a concentration that moves from high to low, and active transport has a concentration that moves from low to high. (Hope this helps to answer your question!)
What two requirements distinguish osmosis from diffusion?
Diffusion and osmosis are both types of passive transport. The two requirements that distinguish osmosis from diffusion are the presence of a membrane and the type of substance.
How does active transport differ from the process of diffusion across a membrane?
Diffusion is the process in which a certain substance achieves equal concentrations in a specific area. Diffusion across a membrane means that the substance is equally distributed between both sides of the membrane, assuming the substance can pass through that membrane (the membrane is permeable to the substance).Active transport is just that, active. It requires energy because it is usually moving substances to a place where they would not naturally move or increases the rate of their disbursing. Active transport can move molecules against a concentration gradient, whereas diffusion cannot.Simply, active transport means that energy is needed to transport the object/molecule while diffusion is a naturally occurring process dependent on the concentration gradients between the membrane.
What do osmosis and diffusion have in common?
They're transferring a substance from a High concentrate to a low concentrate.

Name and describe the condition that exists when the diffusion of a particular substance is complete?
Passive Transport (:
Does diffusion or osmosis take place in the nervous system?
Diffusion is the process of cell transfer within the nervous system. It is diffusion of the ions that allows for transport and solubility to complete the process. Osmosis is used in other cellular areas.
How is the active transport different from diffusion?
The main difference is that diffusion does not require energy and active transport does require energy. Just for the record diffusion has a concentration that moves from high to low, and active transport has a concentration that moves from low to high. (Hope this helps to answer your question!)
What is the movement of a substance from an area of high concentration to an area of low concentration?
passive transport Movement down a concentration gradient is known as diffusion.

Give 2 examples of passive transport?
Passive transport is when molecules pass freely through the membrane moving from the higher concentration area to the region of lower concentration. Three examples of this are diffusion, osmosis, and active transport.
What is passive membran transport?
The diffusion of substances across a membrane is called passive transport. Molecules move from where the substance is more concentrated to where it is less concentrated.
What 3 ways can substances enter and leave a cell?
Substances can move in and out of a cell in several ways. Diffusion is when a substance will distribute itself in or out of a cell until the distribution on both sides of the cell is balanced. Active transport is when a cell transports a substance across the cell membrane that would not normally be able to pass through. Osmosis is the movement of water from areas with few dissolved dissolved substances to areas with high dissolved substances.
Is diffusion an example of active transport or passive transport?
Diffusion is an example of passive transport, like osmosis(the diffusion of water through a membrane).
Is diffusion a passive transport?
diffusion
