i like your analogies with the sharing of electrons and the insect input-output with its brain. i think think scientific analogies help me understand science and the world better;) numbers in temperature with units in science seem a lot, but its so cool and i find myself being able to process it. i realize there is another example of negative feedback in thermostats say the room temperature is 72 degrees and you turn up the heat to 90 degrees, it will take time for the heat to rise and when it reaches 90 degrees, it levels off so the room temperature doesn’t overheat, i think a thermostat regulates the room’s temperature much like our own body regulates its temperature. the negative feedback mechanism offsets starts to inhibit too much of the product so there is a balance. also an item with more volume absorbs more heat such as a swimming pool absorbs the heat from the sun, however the pot pot of coffee has higher temperature. i’m learning lots from the ap biology book.
