Ohh. Wait but then when do the antibodies attach to the mast cell? In secondary responses its when the pathogen attaches to the antibodies on the mast cell that the mast cell releases histamine right? Could you elucidate the events that take place in the primary allergic response please
ANYYYYONEEEEEE!!! :/:/:/
Is it D?
Yes, it is. But why?
If i were in the exam, I would have chosen D because it is the only answer with number 4 in it. High humidity means that transpiration is low thus transpiration pull force is not working properly so the plant uses the Root pressure instead.
Cuz when the substrate con. Comes to a constant no more product is formed as in reaction comes to a constant
They bind to the mast cells for triggering them to release histamine and cause inflammation. Then an immune response is stimulated, attracting nearby neutrophils to the antigen.the neutrophil recognize and then attach to the antigen, engulf it by phagocytosis, then it is digested and released out of neutrophil by exocytosis, it can also act as antigen presenting cell, then if the antigen is in body-cells, cell mediated response stimulated(t-cells), but if outside cells in tissue fluid then humoral response stimulated(b-cells)
Hi everyone, assalamoalaikum!!
To get things organized in a better way, I am making this thread. As othewise, some queries remain unanswered!
So post your A LEVEL BIOLOGY doubts in this thread. InshaAllah those who can , will help me and you all.
Will try to update this soon, by adding links to some Biology Notes & Links around the forum.
Thanks!
Jazak Allah Khair!

competitive inhibitors are the type of inhibitors who keep on attaching and detaching from the substrate that why increasing the substrate means more substrate is able to attach so rate of reaction increase hope it helped

Typical plant cell - 40 micrometers.
Nucleic acid present in baseshow come lysosome hav nucleic acid??
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
