For Diffusion To Occur, Which Condition Must Be Met

Diffusion also occurs in pure metals, this is termed self diffusion. Diffusion Mechanism For atoms to move, two conditions must be met. 1) There must be an empty adjacent site 2) The atoms must have enough energy to break the bonds with its neighbor atoms- vibrational energy through temperature increase. MATERIALS SCIENCE 2 DIFFUSIONDiffusion is the process by which molecules move through a substance, seemingly down a concentration gradient, because of the random molecular motion and collision between particles.In the process of diffusion, a substance tends to move from an area of high concentration to an area of low concentration until its concentration becomes equal throughout a space. For example, think about someone opening a bottle of cleaning ammonia in the middle of a room.Since the distribution of molecules occurs in a variety of conditions, diffusion can be classified into two major types: 1) Simple Diffusion It is the process in which substances move across a biologically active semi-permeable membrane along the concentration gradient without the involvement of any other molecules.Surface area and thickness of the plasma membrane: Increased surface area increases the rate of diffusion, whereas a thicker membrane reduces it. Distance travelled: The greater the distance that a substance must travel, the slower the rate of diffusion. This places an upper limitation on cell size.

Diffusion, from an atomic perspective, is just the stepwise migration of atoms from lattice site to lattice site. In fact, the atoms in solid materials are in constant motion, rapidly changing positions. For an atom to make such a move, the following two conditions must be met: (i) There must be an empty adjacent site, andFor diffusion to occur there must be a concentration gradient. Diffusion occurs when particles move from a region of high concentration to a region of lower concentration. Diffusion occurs until there is equal concentration on both sides. Diffusion stops when concentration equilibrium is reached.Diffusion is the passive movement of molecules from an area of high concentration to an area of low concentration.; Passive diffusion is the movement of molecules across a membrane, such as a cell membrane. The movement does not require energy. In facilitated diffusion, a molecule is transported across a membrane with the help of a carrier protein.Diffusion is a type of substance movement that requires no energy to be expended for the substance to move. Simple diffusion occurs when there is no obstacle to the substance so it can diffuse...

Diffusion Mechanisms For an atom to make such a move, two conditions must be met: 1. An empty adjacent site 2. Atom must have sufficient energy to break bonds with its neighbor and then cause some lattice distortion during the displacement. 11/2/2018 7:57 PM Mohammad Suliman Abuhaiba, Ph.D., PE 11because diffusion is process molecules move down a concentration gradient. In other words, the processs by which molecules move from an area of low concentration to an area of high concentration....Diffusion is widely used in various fields such as biology, physics, chemistry, etc. Diffusion can be classified into two main types: Simple diffusion and facilitated diffusion. Simple diffusion A process in which the substance moves through a semipermeable membrane or in a solution without any help from transport proteins.o Have a condition that is at least 10 percent disabling • Vietnam Veterans who were: o Exposed to Agent Orange o Served in the Republic of Vietnam between Jan. 9, 1962, and May 7, 1975 o Served before Feb. 1, 1992, at a diffusion plant in Paducah, Kentucky, Portsmouth, Ohio or Oak Ridge, Tennessee . 2 . o Served before Jan. 1, 1974, atAnswers? Play games to get them! For diffusion to occur, which condition must be met? a) A hypotonic external environment is required.

First Question:

A - a focus gradient

because diffusion is procedure molecules transfer down a focus gradient. In different words, the processs by way of which molecules transfer from an area of low concentration to a space of high concentration. (focus gradient manner regions of opposite rate)

Its now not B as a result of a service is not wanted for molecules to move the membrane in easy diffusion (that's facilitated diffusion)

diffusion in an instance of passive shipping so it doesnt require any power so its now not C

Not E and Dbecause the vesicles and membrane fusion is utilized in endo and exocytosis (lively tranport)

Its now not C because

Second Question:

E - none of the above

endocytosis is lively delivery so it doesn't need a concentration gradient, i'm going to happen although its reached equilibrium so its now not A or B

it does not require a service because it enters thru vesicles so its now not B or C

Vesicle Formation - it if truth be told relies what you realized about vesicle formation: if what is supposed is that pockets form at the cellular membrane and make allowance particles to input, then it breaks off of the cell membrane the D is actaully the proper solution (that is what endocytosis is) if that's not what you discovered then the answerr in E

B - a carrier and a focus gradient

as a result of facilitated diffusion is when molecules can not immediately cross the membrane go through special protein channels instead (so you need the provider) another way facilitated diffusion is the exact same thing as easy diffusion so you continue to nead a focus gradient

not C, D, and E for the similar explanation why question one was once no longer C, D, and E

that leaves A and B and it does require a focus gradient nevertheless it also calls for a service which is why b is the simpler solution

Third Question:
