What determines the direction in a substance diffuses across a membrane?
The concentration gradient determines the direction in which a substance diffuses across a membrane. The concentration gradient is a measure of how the concentration of a substance changes from one place to another.
The difference in concentration of a substance across space is called a?
The difference in concentration of a substance across space is called a concentration gradient. This gradient drives the movement of molecules from regions of higher concentration to regions of lower concentration through processes like diffusion or active transport.
When the concentration of a substance differs from one area to another this is called concentration?
This is called a concentration gradient, which represents the difference in concentration of a substance between two locations. The substance will naturally move down the concentration gradient from areas of higher concentration to lower concentration through processes like diffusion or active transport.
The amount of one substance in a certain volume of another substance is called?
concentration
What is the amount of one substance in a certain volume of another substance is called?
concentration
When a substance changes from a liquid to solid it is...?
When a substance changes from liquid to solid is called freezing.
What is the temperature called at which a substance changes from a solid to a liquid?
The temperature at which a substance changes from a solid to a liquid is called the melting point.
What is a difference between a concentration of a substance is called the?
i think it is homeostasis
The movement of a substance across a concentration difference is called?
diffusion
The transport of a substance across the cell membrane against its concentration gradient is called what?
The transport of a substance across the cell membrane against its concentration gradient is called active transport.
When a substance changes from a liquid to a gas is called?
Its called condensation.
When a substance changes from a solid to a gas it is called?
It is called sublimation.
