Imagine yourself in a dark classroom reading powerpoint slides. if an audience member were to check the internet using her cell phone and causing her screen to light up, chances are that many people would notice the change in illumination in the classroom. however, if the same thing happened in a brightly lit classroom during a discussion, very few people would notice. the cell phone brightness does not change, but its ability to be detected as a change in illumination varies dramatically between the two contexts. this is an example of

Weber's Law

Explanation:

Weber-Fechner's Law relates the physical magnitude of a stimulus to the subjective intensity of a person's sensation. It goes for any sensory perception, be it auditory, visual, thermal, tactile, taste or olfactory. Generally speaking, the Weber-Fechner Law can be stated as follows: the increase in stimulus necessary to produce the minimum increase in sensation is proportional to the pre-existing stimulus. Cell phone light is a stimulus, which is increased in low light situations, so this light is more noticeable in a dark and quiet room than in a room with lots of people talking.

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.

a researcher conducts an experiment on the secretion of a particular hormone in mice. scientists inject mice with a substance that stimulates the production of the hormone. the scientists then test the levels of hormones produced by the mice. the tool used to measure the hormones consistently detects the levels at 10 points lower than the actual hormone levels in the mice. this tool makes measurements, but the measurements aren't .
