C. a rise in blood carbon dioxide concentration
Explanation:
Negative feed back mechanism refers to the control mechanism in which a product of a particular pathway controls the switch on and switch off of that particular pathway.
Since breathing increases the blood oxygen concentration and lowers carbon dioxide concentration and pH. The sensors that regulate the breathing should respond to oxygen concentration as the carbon dioxide is the by-product of respiration and is responsible for increasing blood pH. Thus increased Carbon dioxide levels in blood is the only factor which will trigger breathing.
Recording from single neurons in the brain has shown that neurons responding to specific types of stimuli are often clustered in specific areas. These results support the idea of localization of function.
Localization of function is an idea used in neuroscience. It refers to the idea that functions can be attributed to specific regions of the brain (different brain areas are specialized for different functions).
Territory’s, most kingdoms /kings or queens called it that
Because as humans grow bigger, so does there brain. So the smaller you are, the smaller your brain.
