Solution
-
The best description of the homeostatic mechanism of negative feedback is "Adjustment made by the body to return itself to normal after detecting a change". This is because negative feedback mechanisms work to reverse or negate a change in the body's conditions, bringing it back to its normal state.
-
The role of the pituitary gland in regulating metabolic rate is that "It releases thyroid stimulating hormone". The pituitary gland releases thyroid-stimulating hormone (TSH), which then stimulates the thyroid gland to produce and release thyroxine, a hormone that regulates metabolism.
-
When the amount of thyroid stimulating hormone released from the pituitary gland increases, "More thyroxine is released from the thyroid, metabolic rate increases". This is because TSH stimulates the thyroid gland to produce and release more thyroxine, which in turn increases the body's metabolic rate.
-
The gland located at the top of your kidneys is the "Adrenal glands". These glands produce hormones like cortisol and adrenaline, which help the body respond to stress.
-
The 'flight or fight' response that is not caused by the release of adrenalin is "Blood redirected from skeletal muscles to digestive system". In a fight or flight response, adrenaline causes blood to be redirected to the muscles, not away from them.
-
The hormone that is not controlled by a negative feedback mechanism is "Adrenalin". Adrenaline is released in response to stress or danger and is not typically regulated by a negative feedback loop like the other hormones listed.
