T killer cell or Cytotoxic T cells are the cells in animals that are used to destroy bacteria and viruses after combining with lysosomes.
<u>Explanation</u>:
The T cells kills the bacteria and virus. The T cells can easily identify the pathogen when combined with the lysosomes. The activated T cells releases a material called perforin. This substance gets into the walls of the affected cell and punctures its walls. Due to hole in the walls, there happens discharge of fluid and electrolytes, which leads to the death of the cell. The substance secreted is the cytolytic proteins from the lysosome which helps in destruction of the infected cells.
The term agglomeration is an economic term used to refer to the phenomenon of firms being located close to one another. There are a number of components we'll explore later in this lesson, but for now, just remember that agglomeration relates to clusters of population or business activity.
Agglomeration, the adhering of particles to each other or to strong surfaces, is a characteristic marvel.
Agglomeration also changes the mass attributes of particulate solids typically to improve things. Bigger particles have less residue, display improved stream conduct, and highlight decreased staying inclinations.
Hence, the right answer for the fill up the blank is "Agglomeration"
