Chemotaxis
Chemotaxis, the directed movement of entities like bacteria, immune cells, and ants in response to chemical signals, is integral to biological processes and medical research. This behavior is key in understanding disease mechanisms, aiding in the development of targeted treatments, and offers insights into ecological and evolutionary dynamics.

Regulated Expression
Gene expression regulation dictates the timing and location of gene activation in cells, ensuring precise protein production. This regulation spans several stages, from DNA accessibility to protein synthesis. External signals and internal networks shape these patterns. Any disruptions can lead to conditions like cancer.

Exaptation
Exaptation, a key concept in evolutionary biology, refers to the repurposing of existing traits for new functions. This process plays a significant role in both biological and cultural innovation, enabling rapid evolutionary responses. Its identification, however, is complicated due to the complexity of historical evolutionary pressures.
