They want to be a equilibrium (have the same concentration both inside and outside the semi-permeable membrane). Therefore they will move from a higher concentration to a lower in an effort to gain equilibrium. This does not require energy, unlike active transport.

What is the most important factor in explaining why diffusion occurs spontaneously?
The most important factor in explaining why diffusion occurs spontaneously is the tendency of particles to move from an area of higher concentration to an area of lower concentration in order to reach equilibrium. This process is driven by the random motion of particles and does not require an external energy source.
How do concentration gradients work?
Concentration gradients involve the movement of particles from an area of higher concentration to an area of lower concentration. This movement occurs due to the natural tendency of particles to spread out and reach equilibrium. Diffusion is the primary mechanism involved in the movement of particles along a concentration gradient.
How does facilitated diffusion work?
Facilitated diffusion is a process where molecules move across a cell membrane with the help of transport proteins. These proteins create a channel or carrier to allow specific molecules to pass through the membrane. This movement is passive and follows the concentration gradient, meaning that molecules move from an area of high concentration to low concentration.
Which way do molecules move during active transport?
Molecules move against their concentration gradient, from an area of low concentration to high concentration, in active transport. This process requires energy input to pump the molecules across a membrane using specific proteins like pumps or carriers.
How does secondary active transport work?
Active transport requires energy (ATP, GTP, etc) to work against the electrochemical gradient. Passive transport works with the electrochemical gradient and does not require energy. (Think diffusion)
Does simple diffusion work with or against the concentration gradient?
I think that it is something
How is diffusion different from active transport?
Diffusion is a passive process where molecules move from an area of high concentration to low concentration, while active transport requires energy to move molecules against their concentration gradient from low to high concentration. Active transport involves carrier proteins or pumps to transport molecules, while diffusion does not require any specific proteins.
How can molecules move without diffusion or osmosis?
Molecules can move through processes like active transport, facilitated diffusion, or bulk transport. In active transport, molecules are moved against their concentration gradient with the help of energy. In facilitated diffusion, molecules move across a membrane with the help of carrier proteins. In bulk transport, large molecules are engulfed by the cell membrane and transported inside the cell.
Does osmosis work with or against the concentration gradient?
Osmosis works with the concentration gradient, meaning that it involves the movement of water molecules from an area of low solute concentration to an area of high solute concentration in order to equalize the solute concentration on both sides of the membrane.

Why did whole milk move?
The whole milk moves because of diffusion.The molecules of milk diffuse thorugh the water as in simple diffusion, molecules diffueses from where it is more concentrated to where it is less concentrated to where it is less concentrated (diffusing down its concentration gradient). This leads to dynamic equilibrium; the solute molecules of mile continue to cross the membrane but at equal rates in both directions. Diffusion is a spontaneous process, needing no input of energy. No work must be done to move substances down the concentration gradient.
What types of transport moves molecules along a concentration gradient?
Passive transport mechanisms like simple diffusion, facilitated diffusion, and osmosis move molecules along a concentration gradient without using energy. Active transport mechanisms, including primary and secondary active transport, use energy to move molecules against their concentration gradient.
How do faciliated diffusion and active transport differ?
Facilitated diffusion is a passive process where molecules move across a membrane with the help of transport proteins, following their concentration gradient. Active transport requires energy input (ATP) to move molecules against their concentration gradient with the help of transport proteins.
A form of passive transport that uses transport proteins-?
Facilitated diffusion is a form of passive transport that uses transport proteins to facilitate the movement of specific molecules across a cell membrane. These proteins help molecules move down their concentration gradient without requiring energy input from the cell.
How does facilitated diffusion work?
Facilitated diffusion is a process where molecules move across a cell membrane with the help of transport proteins. These proteins create a channel or carrier to allow specific molecules to pass through the membrane. This movement is passive and follows the concentration gradient, meaning that molecules move from an area of high concentration to low concentration.
What is the function of passive transport?
Passive transport is a biological process that allows molecules to move across a cell membrane without the use of energy. It occurs down the concentration gradient, from an area of high concentration to an area of low concentration. Common types of passive transport include simple diffusion, facilitated diffusion, and osmosis.
