Detailed explanation-1: -Solute concentrations across a semi-permeable membranes influence the movement of water and solutes across the membrane. It is the number of solute molecules and not the molecular size that is important in osmosis. Osmoregulation and osmotic balance are important bodily functions, resulting in water and salt balance.

Detailed explanation-2: -Osmoregulation is the control of water levels and mineral ions (salt) in the blood. Water levels and mineral ions in the blood are controlled to keep the concentrations the same inside the cells as around them. This protects cells by stopping too much water from entering or leaving them by osmosis.

Detailed explanation-3: -Osmotic regulation, or osmoregulation, keeps these solutes at the ideal concentrations. Osmotic homeostasis is maintained despite the influence of external factors such as temperature, diet, and weather conditions.

Detailed explanation-4: -The most important factor that affects the rate of osmotic movement of water is the concentration of the solute in the solutions on both sides of the membrane. Water moves across the membrane from a higher concentration of solute to a lower concentration of solute.
