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.
<em>For example, opening the door of a microwave oven as soon as its timer beeps.</em>
<em>Example II; When your body touches a hot object, you quickly move away and feel some pain subsequently. </em>

Some physicians are aloof or awkward in addressing concerns regarding the female reproductive system as there are certain practices, beliefs, knowledge, and attitudes that can affect the patient’s interaction with a physician. Because of this, the physician may not be able to offer the proper management and the physician may be at risk for lawsuits. For instance, a patient with gynecologic problem refuses internal examination of the genitalia; the physician cannot make an objective examination and management will be compromised.<span> </span>
Answer: In barren areas of chromatin.
Explanation:
Elite controllers are considering individuals with human immunodeficiency of virus-1 which means that it can maintain undetectable plasma virus levels and it is very rare.
60% of the elite controllers' HIV material is found in areas that are barren areas of chromatin and also called ''gene deserts''.
They contain about 0,12 percent of the integration sites which means that there HIV can plan its genes physically but that does not change the fact that 60% of the elite controllers' HIV genetic material is found in those areas.
