One of our homework questions in Anatomy 1 states
Describe the relationship between homeostatic imbalance and disease.
I understand that homeostasis is what our bodies use to keep balance and regulation.
Is this question something along the lines of;
When our bodies catch a flu/virus the body fights off the disease by giving us a fever. The fever fights off the infection by chemical responses that come from the receptor detecting change in the body and trying to get all levels of each system back to it's regular functioning levels?
Thank you,

Which of the following statements is CORRECT in describing the positive feedback control systems in our body?
Group of answer choices
The response counteracts the stimulus, shutting off the response loop.
The response reinforces the stimulus, sending the variable farther from the set-point.
The response is able to move the variable closer to the set-point.
The response is able to move the variable farther from the set-point by suppressing the stimulus.

- Read the following statements: ANIMAL AND PLANT PHYSIOLOGY Both plant biologists and animal biologists seek to understand how their focal organisms have evolved to interact with the environment. Despite this similarity in goals, the differing biology of plants and animals as well as other factors have led these scientific communities to diverge. Scientific discoveries that have occurred in each community in relative isolation may advance progress in the other community and set the stage for broad scientific syntheses.
