When in its life cycle does a B cell first exhibit its particular surface antibody?
A B cell exhibits its particular surface antibody when it reaches the mature stage, which typically occurs during the later stages of its development in the bone marrow or lymphoid tissues. This occurs after the B cell undergoes rearrangement of its immunoglobulin genes and passes through different stages of maturation to become a fully functional B cell capable of recognizing specific antigens.

What is the difference between type a blood cells and type b cell?
Type A and B red blood cells differ in the antigens they express on the cell surface. The still carry out the same tasks (transportation). The antigens on the surface of these cells are what is recognised by the immune system - so that it knows the cell is part of the body and not foreign.
Is A B toxin a membrane disrupting toxin?
No, A B toxin is not a membrane disrupting toxin. It consists of two subunits: the A subunit, which is the active toxic component, and the B subunit, which is responsible for binding to cell surface receptors and facilitating the entry of the A subunit into the cell.
Two models of cells are shown below. Why would model B be better for moving nutrients in and out of the cell?
B has smaller cells but more surface area than A.
How can B cell mature into plasma cell?
The surface immunoglotulin that serves as the B-Cell antigen receptor (BCR) has two roles in B-cell activation. First, like the antigen receptor on T cells, it transmits signals directly to the cell's interior when it binds antigen. Second, the B-Cell antigen receptor delivers the antigen to intracellular sites where it is degraded and returned to the B-cell surface as peptides bound to MHC class II molecules.
What are the differences between Bcell receptors and Tcell receptors?
there are different types of b cell and t cell. both are lymphocytes, a subclass of white blood cell. the t cells are mainly used in identifying antigens and releasing chemicals which attact macrophages (big immune cells which 'eat' antigens), to destroy the antigen. b cells are used in the production of antibodies. when they encounter a new antigen, plasma cells and memory cells are formed from the division of a b cell. the memory cell remembers the antigen and which antibody to use, while the plasma cell makes the antibodies to fight a particular antigen or class of antigens
What is an example of a function that is continuous and bounded on the interval a b but does not attain its upper bound?
A function whose upper bound would have attained its upper limit at a bound. For example, f(x) = x - a whose domain is a < x < b The upper bound is upper bound is b - a but, because x < b, the bound is never actually attained.

Is a animal cell a prokaryotic cell or eukaryote cell?
All animal cells are eukaryote. A membrane bound nucleus and many membrane bound organelles.
What are the lower bound estimate and the upper bound estimate found by rounding to the greatest place 937 and ndash 156 A. lower bound 700 upper bound 800 B. lower bound 700 upper bound 900 C. lower?
The answer is B.
Small membrane-bound sac used for transport?
A vesicle is a small sac made of membrane that transports materials within a cell. Vesicles can move molecules within the cell, between different parts of the cell, or to the cell's surface for secretion.
What is the difference between type a blood cells and type b cell?
Type A and B red blood cells differ in the antigens they express on the cell surface. The still carry out the same tasks (transportation). The antigens on the surface of these cells are what is recognised by the immune system - so that it knows the cell is part of the body and not foreign.
Macfarlane burnet theory about antigen antibody reaction?
The Burnet theory about antigen antibody reaction is a basic concept about how we make antibodies specific to a foreign substance which has the ability to induce an immune response (antigen). Each B cell displas one unique type of B cell receptor on their surface (which is basically a membrane bound antibody). Therefore many B cells, each expressing its own type of B cell receptor are needed to cover the inexhaustable number of antigens that are possible, in the hope that one type of B cell receptor will be able to recognise the shape of that antigen. If one B cell does recognise the antigen in question, then this B cell will become activated to make many clones of itself, which will obviously carry identical B cell recptors which fit the antigen. |Therefore the clonal selection theory by Burnet is about antibody antigen interactions which result in the 'best-fit' B cell receptor inducing a reaction to tell the B cell carrying the receptor to multiply and produce lots of identical antibodies which can then be secreted to bind to the antigen they are specific for.
