Your body uses feedback mechanisms to help maintain a stable internal environment called homeostasis. Changes can come from outs
ide or inside the body and the body must respond to these adverse changes to return to a steady state. One such example is what happens when you go for a run on a hot summer day and your body temperature increases. According to the diagram, one of the mechanisms used to cool down is vasodilation. Similar mechanisms are also used when your body temperature drops due to a cold environment. Which of these would NOT help return a body to homeostasis by increasing body temperature? A) shivering
B) vasoconstriction
C) muscles contract
D) increasing blood pressure
Populations evolve, individuals do not. It is incorrect to say that individuals adapt to their environment because adaptation occurs as a result of random mutations. Changes in the individual during its lifetime, such as phenotypic plasticity, is not adaptation.
