<span>In case of normal cells, the nuclei is smaller than the size of nuclei in case of cancer cells. Another different lies in the shape of cells. In case of normal cells, the shape of the cells is somewhat symmetrical while in case of cancer cells, the shape of the cells is different. Another difference lies in the distance between the cells. In case of normal cells, there is a gap between the cells while in case of cancer cells, they are grouped together.</span>
Answer;
The above statement is true
Explanation;
-Complement is a system of plasma proteins that can be activated directly by pathogens or indirectly by pathogen-bound antibody, leading to a cascade of reactions that occurs on the surface of pathogens and generates active components with various effector functions.
-C3b is the larger of two elements formed by the cleavage of complement component 3, and is considered an important part of the innate immune system. C3b is potent in opsonization: tagging pathogens, immune complexes (antigen-antibody), and apoptotic cells for phagocytosis.
