True

False

Solution

Answer: True, Some homeostatic imbalances cause a variable that is normally controlled by negative feedback to be abnormally controlled by positive feedback.

For example, In the case of heart failures. Due to aging of the body, the negative feedback mechanism fails and gets overwhelmed and the positive feedback mechanism tries to compensate for the failed negative feedback. This leads to the enlargement of the heart accompanied by hypertension. Both these conditions eventually lead to heart failure.
