Phagocytosis of microbes by macrophages is enhanced by both the binding of antibodies to the surface of microbes & antibody-mediated opsonization of microbes
What is the function of phagocytosis?
Phagocytosis is the cellular process through which particles bigger than 0.5 m in diameter, such as bacteria, foreign substances, and apoptotic cells, are ingested and eliminated.
- Phagocytosis is found in many different types of cells and is hence an important step for tissue homeostasis.
- However, only specialized cells known as professional phagocytes are capable of high-efficiency phagocytosis.
- Among these specialized cells are macrophages, neutrophils, monocytes, dendritic cells, and osteoclasts.
Phagocytosis occurs in four stages:
I identification of the particle to be swallowed,
ii) activation of the internalization process,
iii) development of a specialized vacuole known as a phagosome,
iv) maturation of the phagosome to turn it into a phagolysosome.
Hence, the correct option is A

Answer: Endosmosis is the movement of water from outside to inside of the cell. In hypotonic solution, concentration of the solvent is high outside the cell. Therefore, water/solvent enters the cell causing the contents of the plant cell to press against the cell wall. In hypertonic solution, exosmosis will take place, i.e. the solvent/water will move from inside to outside of the cell.
Explanation:
Each organelle has it's own specific function to help the cell survive. The
nucleus of a eukaryotic cell directs the cell's activities and stores DNA.
Eukaryotes also have a golgi apparatus that packages and distributes
proteins. Mitochondria are the power house of the cell and provide the cell
with energy
Answer:
The Lactaid is the independant variable and the amount of glucose is the dependant variable
Explanation:
Since the milk is treated with lactaid, the result of this is the amount of glucose in the milk
