Cullis is a term used in many fields, including biology, chemistry, and physics. It refers to the process of removing unnecessary or unwanted material from a sample or object. In biology, for example, culling refers to the process of eliminating weak or sick animals from a herd to ensure the health and survival of the remaining animals.
