What name is given to the process by which substances pass into or out of a cell from an area of higher concentration to an area of lower concentration?
diffusion
What else can I help you with?
Process in which molecules move from and area of higher concentration to an area of lower concentration?
It is Diffusion because it describes the spread of particles through random motion from regions of higher concentration to regions of lower concentration ill c u if ur cheating dustin
What is the difference in the concentration of a substance across a space is called concentration?
The difference in concentration of a substance across a space is called a concentration gradient. It represents the change in concentration over a given distance and drives processes like diffusion and osmosis. Substances move from areas of high concentration to areas of low concentration along the concentration gradient to achieve equilibrium.
Passive transport requires no what?
Passive transport occurs when substances cross the plasma membrane without any input of energy from the cell. No energy is needed because the substances are moving from an area where they have a higher concentration to an area where they have a lower concentration. Concentration refers to the number of particles of a substance per unit of volume. The more particles of a substance in a given volume, the higher the concentration. A substance always moves from an area where it is more concentrated to an area where it is less concentrated. It's a little like a ball rolling down a hill. It goes by itself without any input of extra energy.
When molecules move down the concentration gradient it means they are moving from high to low or low to high?
When molecules move down the concentration gradient, they are moving from an area of high concentration to an area of low concentration. This movement occurs spontaneously to equalize the concentration of molecules in the given environment.
What Contains a relatively small amount of solute per given amount of solvent?
A dilute solution contains a relatively small amount of solute per given amount of solvent. Dilution involves adding more solvent to a concentrated solution to reduce the concentration of the solute. This process results in a solution with a lower concentration of solute molecules.
How are dilutions of substances prepared given a prepared concentration?
KDIE
What percentage of the solution is dissolved substances?
This is the concentration of a solute in a solvent at a given temperature and pressure.

Is it true that water tends diffuse from a region where it is lees concentrated to a region where it is highly concentrated?
It is not true. All substances tend to diffuse from an area of higher concentration to that of lower concentration. This is called passive transport(no energy required), or in the case of water, Osmosis. However, if given energy, they can also move from an area of lower concentration to that of higher concentration. This process is called active transport.
What is the given to diffusion of water across a membrane?
The diffusion of water across a membrane is primarily governed by the concentration gradient of solutes on either side of the membrane, a process known as osmosis. Water molecules move from an area of lower solute concentration (higher water concentration) to an area of higher solute concentration (lower water concentration) until equilibrium is reached. This movement occurs through specialized channels called aquaporins in biological membranes, facilitating rapid water transport. Additionally, temperature and pressure can influence the rate of diffusion.
What is the name given to the process that caused the movement of the dye?
The process that caused the movement of the dye is called diffusion. Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration, resulting in a uniform distribution of the dye molecules. This process is driven by the random thermal motion of molecules and is a fundamental concept in chemistry and biology.
What does the word diffusion mean?
Diffusion refers to the process by which particles spread out evenly in a given space due to their random movement. This occurs from an area of high concentration to an area of low concentration until equilibrium is reached. It is a fundamental principle in various scientific fields including physics, chemistry, and biology.
What is the name given substances whose pH is less than 7?
acidic, alkaline higher than 7
What is the difference in the concentration of a substance across a space is called concentration?
The difference in concentration of a substance across a space is called a concentration gradient. It represents the change in concentration over a given distance and drives processes like diffusion and osmosis. Substances move from areas of high concentration to areas of low concentration along the concentration gradient to achieve equilibrium.
What is the relationship between concentration and molarity in a solution?
Concentration and molarity are related in a solution because molarity is a way to measure concentration. Molarity is the number of moles of solute per liter of solution, so it gives a precise measurement of how much solute is dissolved in a given volume of solvent. Therefore, the higher the molarity, the higher the concentration of the solution.
What is the special name given to water diffusing through a membrane?
The special name given to water diffusing through a membrane is "osmosis." This process involves the movement of water molecules from an area of lower solute concentration to an area of higher solute concentration through a selectively permeable membrane, aiming to achieve equilibrium. Osmosis is crucial for maintaining cellular function and homeostasis in living organisms.
Which process explains the change in the positions of moelcules after five hours?
The process that explains the change in the positions of molecules after five hours is diffusion. Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration, driven by the random motion of particles. Over time, this movement leads to a more uniform distribution of molecules within a given space. Factors such as temperature and the medium in which diffusion occurs can affect the rate of this process.
