Transport
This process is called diffusion, where molecules of one substance spread out and become uniformly distributed within another substance. It occurs due to the random motion of molecules and the tendency to reach equilibrium. Diffusion is essential for various processes in nature, such as the exchange of gases in the lungs or the movement of nutrients into cells.
Dissolution refers to the process of breaking down or disintegrating a solid substance into smaller particles by a solvent, usually a liquid. This allows the solid substance to become evenly distributed within the solvent, resulting in a homogeneous mixture.
Substances enter and leave cells through processes such as diffusion, facilitated diffusion, active transport, and endocytosis/exocytosis. Once inside the cell, substances can become distributed within cells through diffusion, cytoplasmic streaming, vesicular transport, and interactions with organelles.
A substance that dissolves in water is called a "soluble" substance. When it dissolves, it forms a solution, where the solute (the substance being dissolved) is evenly distributed within the solvent (water). Common examples include salt and sugar. In contrast, substances that do not dissolve in water are termed "insoluble."
"Soluble" refers to a substance's ability to dissolve in a solvent, usually water, to form a homogeneous solution. If a substance is soluble, it means it can be evenly distributed within the solvent to create a clear solution.

A non-uniform mixture is a combination of substances where the components are not evenly distributed throughout the mixture. This means that there are regions within the mixture where one substance is more concentrated than another. Examples include sand mixed with iron filings, where the iron is not evenly distributed throughout the sand.
The volume distribution is the theoretical volume into which (for example a drug) is distributed into the body. The apparent volume is the volume into which the drug is KNOWN to distribute in the body.
The leaves of Aloe Vera function mainly to store water and nutrients, as well as to conduct photosynthesis. The gel-like substance found within the leaves is known for its medicinal properties and is commonly used in skincare products for its soothing and healing effects.
When a substance changes state, Energy within the substance is gained or lost, but the composition is unchanged.
Temperature is a measure of the energy of motion of particles in a substance. It provides information about how fast the particles are moving within the substance.
