1. In Genetics:
* Carrier: An individual who carries one copy of a recessive gene associated with a genetic disorder but does not exhibit the disorder themselves. They can pass the gene to their children, who may or may not inherit the disorder depending on the other parent's genetic makeup.
2. In Biology:
* Carrier protein: A protein embedded in a cell membrane that facilitates the movement of specific molecules across the membrane. These proteins can be passive (allowing movement down a concentration gradient) or active (requiring energy to move molecules against a concentration gradient).
3. In Chemistry:
* Carrier molecule: A molecule that binds to another molecule (usually a smaller molecule) and transports it to a different location within a cell or organism. Examples include carrier proteins and enzymes.
4. In Physics:
* Charge carrier: A particle that carries an electric charge. Examples include electrons, protons, and holes.
5. In Technology:
* Carrier wave: A high-frequency radio wave used to transmit information in radio communication. The information (audio, video, data) is superimposed onto the carrier wave through modulation.
