This describes a negative or positive feedback loop.arrow_forward
- Positive feedback loops are the opposite of negative feedback loops. In a positive feedback loop, any change in the original variable triggers mechanisms that actually push the variable further in the direction of the change. Imagine that body temperature was regulated in this way. Briefly explain what would happen.arrow_forwardThe presence of a full bladder triggers the bladder to contract. As a little urine is released, this causes more contractions, which will completely empty the bladder.

- Which statement regarding thermoregulation is TRUE? ectotherms thermoregulate by moving between sunny and shady locations whereas endotherms do not thermoregulate endotherms thermoregulate by producing heat through metabolic reactions whereas ectotherms do not thermoregulate ectotherms and endotherms both thermoregulate, but they do it through different methodsarrow_forwardcreate your own diagram by illustrating how the positive and negative feedback mechanism works. You should use specific condition in the body like (temperature regulation, osmotic balance and glucose levels).

Is this an example of negative or positive feedback? Explain reasonsarrow_forwardThe pancreas releases the hormone_______ when blood glucose levels become too high; it causes many cells of the body to take up glucose. When the pancreas produces too little of this hormone, or body cells cannot respond to it, a disorder called________ results._______ is released when blood glucose levels become too low; it causes the liver to break down the starch-like storage molecule_______and release glucose into the blood.arrow_forward
