Question

cells rely on water to transport nutrients and wastes because water can dissolve many substances. which property of water explains this? water is cohesive, sticking to other water molecules. water is nonpolar. water is polar, allowing it to dissolve ions and other polar molecules. water expands as it heats up.

Explanation:

Polarity of water enables it to dissolve many substances like ions and polar molecules, which is crucial for transporting nutrients and wastes in cells. Cohesion is about water - water attraction, water being non - polar would not allow for such dissolving ability, and expansion with heating is not related to dissolving.

Answer:

Water is polar, allowing it to dissolve ions and other polar molecules.
