Answer:
The body will overheat
Explanation:
If the brain of an individual does not receive input that the body was starting to heat up on a hot day, <u>the setpoint temperature of the body would be exceeded and the body will overheat. If the condition persists for a while, the entire systems of the body may shut down due to overheating. </u>
Normal homeostatic response requires that the brain (the control center) receives a message from the skin (the sensor) about a rise in the body's temperature. In turn, the brain will set mechanisms that will bring the body's temperature back to normal in motion, including vasodilation of the blood vessels in the skin to allow more blood into the skin which in turn causes more heat loss to the surrounding.<em> Thus, an individual starts sweating and the evaporation of the sweat causes cooling and a return of the body to the setpoint temperature.</em>
Answer: research it? i dont know
Explanation:
No, what determines a dominant gene is how many copies of that gene exists within the parent. This doesn't mean it will be the most common because of recessive genes. It doesn't matter how many copies a dominant gene has, a recessive gene can still appear in the offspring.
Answer:
Photoperiodism
Explanation:
The term "photoperiodism" was coined to describe a plant's ability to flower in response to changes in the photoperiod: the relative lengths of day and night. Because flowers produce seeds, flowering is crucially important for the plant to complete its life cycle.
