Answer:
stimulus control.
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). All living organisms (both plants and animals) respond to changes in their environment and as such an appropriate reaction or response 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.
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.
Hence, when a behavior is elicited by a stimulus without additional prompts and reinforcers, stimulus control has been attained.
For example, opening the door of a microwave oven as soon as its timer beeps.
Answer: D) It shot air into the molten iron, making it hotter and eliminating impurities.
The Kelly-Bessemer process consists of removing impurities from the iron by oxidation with air that is blown through the molten iron. This raises the temperature of the iron mass and keeps it molten. The Kelly-Bessemer process was the first inexpensive industrial process for the mass production of steel.
The process is named after the inventor Henry Bessemer in 1856, although it is said to have been independently discovered by American inventor William Kelly in 1851.
