Stimulus in biology can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal).
Explanation:
Stimulus in biology can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). Thus, all living organisms (both animals and plants) respond to changes in their environment and consequently, an appropriate response or reaction is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.
In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ. Therefore, the senses are necessary for behavior because stimuli must be sensed in order to respond.
Stimulus control can be defined as a phenomenon that arises when a living organism responds or behaves in the presence of a stimulus and in another way in the absence of a stimulus.

Development of tissue typing changed organ transplantation as
Tissue typing minimizes the chance of rejection
Explanation:
Before tissue typing the chances of rejection of organs y the body of the person needing a transplant was very high and it was a dangerous procedure with little chance of success.
Tissue typing is a process by which the sample tissue of the donor is matched with the sample tissue of the patient in need of help. This makes it viable for the person to know if the organs will be rejected or not before the actual surgery takes place and has allowed for greater successes in transplant thus.
