Please give me the answer to the A-level Biology Question Could you explain the difference between passive diffusion and facilitated transport?

The answer to this A-level Biology question could be that active diffusion occurs without transmembrane proteins while facilitated transport requires transmembrane proteins for molecules to pass through cell membranes, thus allowing for reabsorption of water into circulation which helps regulate water balance. Additionally, it is important to understand How does Acetylcholine act on a neuronal synapse, and how is it released? Acetylcholine is released from neurons located in the presynaptic membrane when stimulated by an action potential. The release of Acetylcholine then triggers a cascade of events which leads to the opening of ion channels in the postsynaptic membrane, allowing for the influx of ions and resulting in a postsynaptic potential. This postsynaptic potential can then lead to further action potentials in the postsynaptic neuron. Similarly, Please give me the answer to the A-level Biology Question Could: Explain how anti-diuretic hormone (ADH) is released and acts on the body to regulate water balance? ADH is released from the posterior pituitary gland in response to changes in osmolarity or blood volume and binds to receptors on the kidneys, stimulating aquaporin channels which allow for increased water reabsorption back into circulation. This explains how anti-diuretic hormone (ADH) is released and acts on the body to regulate water balance by increasing water reabsorption back into circulation. To gain a better understanding of this process, it is important to explain how anti-diuretic hormone (ADH) is released and acts on the body in detail. Specifically, ADH is released from the posterior pituitary gland in response to changes in osmolarity or blood volume and binds to receptors on the kidneys. This binding triggers aquaporin channels which allow for increased water reabsorption back into circulation, thus providing an explanation for how anti-diuretic hormone (ADH) is released and acts on the body to regulate water balance. Furthermore, it is important to understand how ADH is released and how it acts on the body once it has been released. Explain how anti-diuretic hormone (ADH) is released and acts on the body to regulate water balance? ADH binds to receptors on the kidneys, stimulating aquaporin channels which allow for increased water reabsorption back into circulation. This explains how anti-diuretic hormone (ADH) is released and acts on the body to regulate water balance by increasing water reabsorption back into circulation.
