When the brain is deprived of oxygen, the mitochondria within neurons stop producing atp. what effect does this have on the membrane potential? why?
The neuronal membrane potential depends on different concentrations of sodium and potassium on either side of the membrane. Ionic concentration gradients are established by the action of the sodium-potassium ion pump, an enzyme that requires ATP. Without ATP, the pump will not function. As a result, the resting membrane potential will not exist and the brain will not function.
What is neuronal membrane?
The neuron and its ionic components can be treated using the ideas mentioned above.
The neuron's plasma membrane is only minimally permeable to Cl and Na+ and extremely permeable to K+. A balance between a high concentration of Na+ and a high concentration of Cl, as well as modest amounts of impermeant anions like bicarbonate, phosphate, and sulfate, is what keeps the extracellular fluid's electroneutrality. The concentration of Cl in the cytoplasm, where K+ concentration is high, is substantially lower than what is required to balance the sum of the positive charges. There, negatively charged impermeant proteins and phosphates keep the environment electroneutral.

In addition to transporting oxygen from the lungs to the tissues, hemoglobin is also involved in transporting carbon dioxide from the tissues to the lungs. how is this accomplished?
The correct option is (C) Carbon dioxide reacts with an amino group to stabilize the deoxyhemoglobin state.
In addition to transporting oxygen from the lungs to the tissues, hemoglobin is also involved in transporting carbon dioxide from the tissues to the lungs where, Carbon dioxide reacts with an amino group to stabilize the deoxyhemoglobin state.
How does hemoglobin contribute to the movement of carbon dioxide from the tissues to the lungs?The transport of carbon dioxide in the blood is influenced by a number of factors. First, blood contains more carbon dioxide soluble molecules than oxygen. The plasma contains 5–7% of the total dissolved carbon dioxide. Second, carbon dioxide can enter red blood cells and bind to hemoglobin or it can bind to plasma proteins. In this form, 10% of the carbon dioxide gets transported. A substance known as carbaminohemoglobin is created when carbon dioxide binds to hemoglobin. Hemoglobin and carbon dioxide can bind to one other again. As a result, when it gets to the lungs, the carbon dioxide can separate from the hemoglobin without restriction and leave the body.Third, the bicarbonate buffer system is responsible for transporting 85% of the carbon dioxide molecules.Learn more about the CO₂ transfer with the help of the given link:

Water is a polar molecule that exhibits the properties of adhesion and cohesion. identify the examples as either cohesion, adhesion, or both.
Water is a polar molecule and exhibits both properties of adhesion and cohesion.
Water molecules possess strong cohesive forces due to their ability to form hydrogen bonds with one another. Cohesion is the scientific term for molecules' affinity towards other molecules of their sort. Surface tension, a phenomenon that causes a liquid's surface to have a tendency to resist rupturing when subjected to tension or stress, is caused by cohesive forces. Adhesion, which is the attraction of molecules of one kind to molecules of another kind, can be exceedingly powerful for water, especially when those other molecules have positive or negative charges. For instance, adhesion enables water to ascend through minute capillary tubes submerged in liquid. The capillary activity that causes this upward movement against gravity depends on interactions between water molecules (cohesion) also on the attraction of water molecules to the tube's glass walls (adhesion). We can infer from the surface tension and capillary action phenomena that water demonstrates both cohesion and adhesion qualities.

After soaking for one hour in a solution of unknown concentration, a slice of potato appears to be very soft and limp. you can determine that the solution is:______
If the potato slice becomes soft and limp after soaking for one hour in the solution, the solution is hypertonic.
What is a hypertonic solution?In biology, a hypertonic solution is a solution with more solute concentration than it is found in the sap of any other cell placed in it.
Such solutions have lower water potential than the cells placed in them. Thus, water will readily move by osmosis from the sap of the cells into the solution.
Cells that are placed in hypertonic solutions, therefore, usually end up becoming flaccid as a result of water loss.
