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.

<em>Example II; When your body touches a hot object, you quickly move away and feel some pain subsequently. </em>
Answer:
4: I should monitor the Eye PH
Explanation:
The pH of the eye is usually monitored when chemical burns occur to the eye, to know if the chemical has altered the PH of the Eye in any way, either by increasing its acidity or alkalinity.
But if Electrical burn occurs, the nurse should monitor the airway for breathing, vital signs, heart rhythm if it is normal or abnormal, neuro vascular status of injured limbs should be assessed too, the client's level of consciousness, and urine output should all be taken note of and not the client's PH level.
