Receptor Site Theory
The theory that states the active substance in a drug has an affinity for a specific chemical constituent of a cell is known as the receptor theory. According to this theory, drugs bind to specific receptors on cells and produce a biological response. This interaction between the drug and receptor is what mediates the pharmacological effects of the drug.

Fred Hoyle is the one that is credited for coining the phrase The Big Bang Theory. The theory itself was first composed from observed by Vestro Slipher in the early 1900s.
It is the current working theory of the origin of the universe. It is the paradigm that Astronomy is based upon. But, new evidence is always being described. The theory itself might change as our knowledge grows.
Simple occupancy theory states that the intensity of a drug's response is proportional to the amount of receptors occupied by that drug. Simply put, the more drugs bind to the receptors the more intense the response.
The theory that a drug attaches itself to specialized cells in the body because of its size, shape, electrical charge, and chemical properties is called the

In specificity theory, each neuron would be tuned to fire for one colorProblems include distribution of color receptors, and the absolute number of colors we can perceive. Also, specificity theory does not account for different intensities
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.
delegation theory
Theory is used used to craft the null hypothesis, which is either proved or disproved by the research itself
Gravitational instability theory....
gas and dust sticks to itself and collapses
Gravitational instability theory
Yes, the Alcubierre Drive relates to a solution to one of Einstein's field equations in his General Theory, although the solution itself does not imply that creation of the drive itself would be a practical endeavor; it remains in the realm of theory.
That is the Deisty theory
It is actually another theory explaining how a new species arises. The theory itself states that a species goes a long time without change, then suddenly changes.
