Relative dating best helps determine fossil age. It's where layers of sedimentary rock and fossils pile up on top of each other; the oldest fossils being in the bottom layer and the youngest in the top.
Opsonization.
Explanation:
- Complement proteins and antibodies coat a microorganism and provide binding sites, enabling macrophages and neutrophils to phagocytize the organism. This phenomenon is termed opsonization.
Opsonization occurs as a result of binding of a molecule called opsonin to the epitope of a pathogen.
Opsonization helps the immune system to select and kill the infected cells instead of targeting all the cells in general.
