Directiоns: An оrgаnism must regulаte the cоncentrаtion of solutes in its body fluids, called 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 the osmolarity increases, nerve cells in the hypothalamus detect the diffusion of water through channel proteins in their membranes (osmosis). These channels activate a signaling pathway that causes a nerve cell to secrete a hormone called vasopressin. A molecule of vasopressin can bind to receptors in the membranes of kidney cells, causing the kidneys to excrete less water as urine. Over time, the osmolarity of blood returns back to its expected range. Alcohol inhibits the release of vasopressin by nerve cells. Typically, a person who has not consumed alcohol has a concentration of vasopressin between 0.5 pg ml-1 and 2 pg ml-1, but a person who has ingested alcohol has a much lower concentration of vasopressin. The figure above shows a path model of the homeostatic system that regulates the osmolarity of blood. This model also describes the effect of alcohol on the concentration of vasopressin in blood. 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 value above each arrow indicates the slope of the linear relationship between the variables connected by the arrow. Use this figure to answer the question. If the concentration of alcohol in the blood was 22 mmol L-1, how would the rate at which the kidneys excrete water change? The rate would ______.
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 ___.
