lana [24]

Answer:

Ox so it was cheese doodles night...She looked at her little girl who was about to become a teen. She tried to think back to when the girl had been younger but failed to pinpoint the exact moment when she had become a little too big to pick up and carry. It hit her all at once. She was no longer a little girl and she stood there speechless with fear, sadness, and pride all running through her at the same time.

The computer wouldn't start. She banged on the side and tried again. Nothing. She lifted it up and dropped it to the table. Still nothing. She banged her closed fist against the top. It was at this moment she saw the irony of trying to fix the machine with violence.

The trees, therefore, must be such old and primitive techniques that they thought nothing of them, deeming them so inconsequential that even savages like us would know of them and not be suspicious.

ludmilkaskok [199]

Answer:

The correct answer is c) opsonins

Explanation:

Opsonization is a process in which proteins like antibodies and complement proteins called opsonins bind to the antigens and get it recognized by the phagocyted which destroys the antigen.

Especially when bacteria is having external capsule than it becomes difficult for phagocytes to attach to the capsular surface as the recognition molecule like membrane carbohydrate of antigen is concealed by capsule.

So to encounter this, antibodies like IgG and complement proteins like C3b attaches to the antigen and get it recognized and opsonized by the phagocytes like macrophages. This opsonization causes the destruction of antigen by enzymatic lysis.
