Answer:
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>
Answer:
We use the first law of motion.
Explanation:
1st: Newton's first law of motion states that an object in motion will stay in motion unless acted upon by a force. ... In swimming, the force produced by the swimmer is equal to the mass of the swimmer multiplied by the acceleration of the swimmer in the water.
