WGU C107 Module 2 Homeostasis and Feedback Loops| Exam Questions with Correct
Answers| Latest Update 100% Solved
The main benefit of using negative feedback instead of positive feedback to control a variable is
that: Negative feedback brings the variable back toward the set point.
The component of a feedback loop that makes the decision about whether or not the variable is
at the set point (normal value) is the: Controller
Heart rate commonly changes in response to challenges to the body, yet there is no direct
sensor for heart rate. This would suggest that heart rate is: A response of the effector
Match the parts of this feedback loop with the correct terminology.
Hypothalamus: Control center
Kidney retention of water: Effector
Body fluid osmolarity: Variable
Osmoreceptors in the hypothalamus: Method of communication
Which of these other organ systems is NOT part of the feedback loop described but would also
likely contribute to homeostasis of body fluid osmolarity? Digestive system
What phrase best describes homeostasis? An ability to maintain a relatively stable
environment
