Upon completion of its proceedings , the Committee shall render its decision . If a bond is very likely to occur , then many receptors will bind to pathogen epitopes , resulting in a high affinity for that pathogen ; if a bond is unlikely to occur , then few receptors will bind to epitopes , and the lymphocyte will have a low affinity for that pathogen . More specialized projects can probe the details of functioning of a single data structure : for instance , you can investigate the expected number of rotations in an insertion or deletion in an AVL tree , the expected number of levels through which an element is sifted in a binary heap during insertion or deletion , etc. Another possibility is to study the cache behavior of various implementations of the same data structure - - write code to allocate storage differently in a tree , or compare linear probing ( next location in the table ) with double hashing or quadratic probing in terms of both running time and number of probes , testing to see if there is a crossover value . The connections can be either random or have some regularities , or structure . Because of the large size and complexity of most pathogens , only parts of the pathogen , discrete sites called epitopes , get bound to the lymphocyte receptors . Probably because it is too difficult to evolve receptor structures that are precisely complementary to epitopes that have never been encountered before . An important consequence of approximate binding is that a single lymphocyte can detect a subset of epitopes , which means that fewer lymphocytes are needed to provide protection against the vast variety of possible pathogens . Unfortunately , my parents decided that sending me to my room was far too humane as although I would be alone , I had plenty of toys to keep my entertained . A lymphocyte has approximately 100 000 receptors on its surface , but because all of these receptors have the same struture ( a lymphocyte is monoclonal ) , a single lymphocyte can only bind to structurally related epitopes .
