Welcome back. Let's look at our next next question. During the warm season. The body reacts to the heat by increasing the blood flow to the skin surface. Which of the following process pairings is correct. And we look at our four answer choices. We see that they involve various pairings with a stimulus sensor and a response. So let's look at those three things and think through what they are in the situation presented in our problem. And then we can match that with a correct answer. So let's look at the information given to us. Well, we know that a stimulus is something in the environment that the body is reacting to. Well right here in our problem, That says, the body reacts to the heat. So the stimulus is the warm temperature and the surroundings. That is what the body is reacting to. And when we look again at what is given to us in the problem. But what happens when the body reacts? What does it do? What is its response? It increases the blood flow to the skin surface. So the response is increasing blood flow to skin surface. So the only piece of information we've got to sort of infer here is the sensor. What part of the body is sensing that stimulus? That warm temperature? Well, how do you sense warm temperature? That's with your skin? Specifically the nerves in your skin? So nerves in skin. So now we just look at our answer choices and see which one corresponds to the three things here that we have matched up. So choice A says the stimulus is the high temperature. So that's correct. That's what we have here, says the sensor is the skin nerve endings, and we wrote nerves and skin so that matches as well, and the response increased blood flow to the skin surface. And that is also what we concluded. So right there, we have identified our correct answer choice A corresponds with what we've figured out. Thanks for watching.
