NegFeedBackBasic/ControlOfCoolerToSummerHeat

POINT!

When room temperature is increased, negative feedback facilitates cooler (function).

① Summer came. Room temperature is increased due to the summer heat. Cooler decreases room temperature. These are in the opposite direction (blue).

② Since these are in the opposite direction, negative feedback facilitates (red) the cooler (function, such as by turning the power on). Because of this, the room temperature-decreasing effect of the cooler strengthens, and the increase in room temperature (red upward unfilled arrow) disappears (increased room temperature decreases to the baseline).

This simply says, when room temperature is increased (during summer), cooler are used. In the present "Step-By-Step Study of Life Sciences", let's call such control blue→red negative feedback.

Challenge Quiz

1.

Because of summer heat, room temperature is increased decreased  正解!, and a cooler increases decreases  正解! room temperature. Since these are in the same direction opposite direction  正解!, negative feedback inhibits facilitates  正解! the cooler (function). With this control, the initial change in room temperature disappears, namely the room temperature increases decreases  正解! (towards the baseline).

2.

When room temperature is increased, negative feedback facilitates inhibits  正解! cooler (function).
