Answer: To separate the inside of the cell from its environment.

The cell membrane is primarily made up of lipids and proteins. It provides protection to the cell by keeping the interior of the cell separated from its external environment.  

It is a selectively permeable membrane meaning that it only allows certain substances to pass through it. It is involved in various cellular processes like cell signaling, cell adhesion, endocytosis, exocytosis etc.

How do phagocytes protect the body
Olin [163]

1) pathogen enters body and releases chemoattractants

2) a phagocyte/macrophage is attracted by these chemicals

3) the phagocyte engulfs the pathogen using its pseudopodia

4) the membranes of both organisms fuse forming a phagosome

5) lysosomers in the phogocyte fuse with the phagosome, forming a phagolysosome

6) these enzymes digest the pahogen (hydrolyse the bonds)

7) the antigens of the pathogen are placed on the surface of the phagocyte making an APC (antigen presenting cell)

Normal values for hemoglobin in males range from 13.5 to 17.5 g/dL. The patient has very serious anema and note he is just 15 months old, and so needs immediate doctor’s attention. The doctor is likely to order a blood transfusion to elevate hemoglobin levels and stabilize the patient before ordering tests to determine cause of anemia.</span>

Overtime, these few resistant insects reproduce more offsprings that carry the resistant genes to these pesticides. As a result, the population of resistant insects become increased more than the non resistant insects.
