Exam: GRE (Verbal)

Definition: A device used to separate and analyze different components in a mixture, producing a visual representation of the results.

Example: The scientist used a chromatograph to analyze the chemical composition of the sample.

Definition: To use a method for separating and analyzing substances in a mixture.

Example: Scientists often chromatograph samples to identify their components.

Definition: Relating to a method used to separate mixtures into their individual components, often used in chemistry and biology.

Example: The chromatographic technique allowed the scientists to analyze the different substances in the sample.

Definition: A method used to separate different substances in a mixture based on how they interact with a moving liquid or gas and a stationary material.

Example: The scientist used chromatography to analyze the components of the chemical mixture.

Definition: The process where certain materials in a cell, especially chromatin, break down or dissolve.

Example: During chromatolysis, the cell's chromatin disintegrates, affecting its function.

Definition: A type of cell that contains pigment and can change color by expanding or contracting, found in some animals like lizards and in certain bacteria.

Example: The chameleon can change its color thanks to the chromatophores in its skin.

Definition: Relating to or containing the chemical element chromium, particularly in its trivalent form.

Example: The chromic acid solution is used in various industrial processes.

Definition: The difference between a color and a reference color that has the same brightness, often used in color television and imaging.

Example: In video processing, chrominance is important for accurately representing colors.

Definition: A shiny, hard metal that is resistant to rust and is used in making strong steel and other materials.

Example: Chromium is often added to steel to make it stronger and more resistant to corrosion.

Definition: A dense area in the nucleus of some cells where certain types of genetic material are concentrated.

Example: The chromocenter plays a crucial role in the organization of genetic material within the cell nucleus.

Definition: The study of how quarks interact with each other through a force called the strong force, which involves particles known as gluons.

Example: In particle physics, chromodynamics helps explain how quarks combine to form protons and neutrons.
