B) diapedesis.
C) cytotoxicity.
D) infection.
E) chemotaxis.

Accepted Answer

Chemotaxis refers to the movement of cells in response to a chemical gradient in their environment, either towards or away from the source of the chemical signal. This is a fundamental process involved in many biological phenomena, such as immune cell recruitment to sites of infection, or the migration of cells during development or tissue repair. Polarity refers to the presence of distinct regions or ends in a cell or molecule, diapedesis refers to the passage of cells through blood vessel walls, cytotoxicity refers to the ability of a substance to be toxic to cells, and infection refers to the invasion and multiplication of pathogenic microorganisms in a host organism.
