Directiоns: An оrgаnism must regulаte the cоncentrаtion of solutes in its body fluids, also referred to as osmolarity. An extreme change in osmolarity will alter the diffusion of water through cell membranes, potentially disrupting the functions of cells. In a healthy human, a homeostatic system ensures that the osmolarity of blood stays within a certain range. When a person becomes dehydrated, their osmolarity increases. When the osmolarity increases, nerve cells in the hypothalamus detect the diffusion of water, also known as osmosis, through channel proteins in their membranes. These channels activate a signaling pathway that causes a nerve cell to communicate with other nerve cells located in the "thirst center" of the hypothalamus. The activity of these nerve cells affect a person's behavior, causing them to seek out and ingest water. The figure above shows a path model of the homeostatic system that regulates the osmolarity of blood. This regulated variable is represented by a dashed box. Other variables are represented by solid black boxes. An arrow connecting one box to another indicates a relationship between two variables. The sign above an arrow (+ or -) indicates whether the variables are positively or negatively related. Use this figure and the information above to answer the question. Select the explanation that best supports the correct answer to the previous question. The actions of this component ___.
The figure аbоve shоws а set оf lineаr relationships among three variables involved in regulating the value of variable x. The figure above shows four path models (A-D) that represent possible homeostatic systems that regulate the value of variable x. The regulated variable is represented by a dashed box. Other variables are represented by a solid black box. An arrow connecting one box to another indicates a relationship between two variables. The sign above an arrow (+ or -) indicates whether the variables are positively or negatively related. Use this information to answer the question that follows. Which path model accurately describes the relationships among the three variables?
