Challenge Quiz
1.
Since increase decrease in room temperature and the effect of a heater are in the same direction, negative feedback facilitates inhibits the heater (function).
2.
Since increase decrease in room temperature and the effect of a heater are in the opposite direction, negative feedback facilitates inhbits the heater (function).
3.
When room temperature is increased decreased , negative feedback facilitates heater (function).
4.
When room temperature is increased decreased , negative feedback inhibits heater (function).
