Definition: A line or ridge that marks the junction of two parts, often found in biological structures.

Example: The rhaphe is an important feature in the anatomy of certain organisms.

Definition: A rare and heavy metallic element that is silvery-white and has a very high melting point. It is used in electrical contacts and high-temperature thermocouples.

Example: Rhenium is often used in jet engines due to its ability to withstand high temperatures.

Definition: The smallest amount of electric current needed to cause a nerve or muscle cell to become active and generate an action potential.

Example: The doctor measured the rheobase to determine the excitability of the patient's nerve.

Definition: Relating to the study of how materials flow and deform under stress.

Example: The rheological properties of the fluid determine how it will behave in different conditions.

Definition: The study of how materials deform and flow under stress.

Example: Rheology is important in understanding how different substances behave when they are mixed or processed.

Definition: A device used to measure how thick or sticky a liquid is, especially for liquids that do not flow easily.

Example: The scientist used a rheometer to analyze the viscosity of the new paint.

Definition: A device that changes the amount of electrical resistance in a circuit to control the flow of electricity.

Example: The technician adjusted the rheostat to increase the brightness of the light.

Definition: A type of synthetic dye used in various applications, including coloring textiles and biological staining.

Example: The scientist used rhodamin to stain the cells for better visibility under the microscope.

Definition: A type of synthetic dye that is red to pink in color and has bright fluorescent properties, often used in coloring materials and biological staining.

Example: The scientist used rhodamine to stain the cells for better visibility under the microscope.

Definition: A rare, silvery-white metal that is very strong and does not easily corrode. It is often used in making special alloys and coatings for other metals.

Example: Rhodium is commonly used to plate jewelry to give it a shiny finish.
