The part of the cell membrane that is polar and allows water to exist is the phospholipid bilayer. The hydrophilic (water-attracting) heads of phospholipids face outward towards the aqueous environment, while the hydrophobic (water-repelling) tails face inward, away from water. This arrangement creates a selective barrier that regulates the movement of substances, including water, into and out of the cell. The presence of proteins and channels also facilitates the transport of water molecules across the membrane.
Water is a good solvent for cells because of its polar structure, which allows it to interact with and dissolve many different types of molecules, such as ions and polar compounds. The abundance of hydrogen bonding in water also helps in breaking down solutes and facilitating various cellular processes. Additionally, water's high heat capacity and ability to regulate temperature make it critical for maintaining cellular homeostasis.
Food coloring is typically polar because it consists of water-soluble molecules that can be easily dissolved in water. The polar nature of food coloring allows it to mix evenly in water-based solutions.

Yes, polar substances dissolve well in water because water is a polar molecule with positive and negative ends that can interact with other polar molecules through electrostatic interactions. This allows substances with polar characteristics to easily dissolve in water.
The higher electronegativity of oxygen allows water to carry partial charges (negative on oxygen, positive on hydrogen). These partial charges allow water to bind strongly with itself, and allows it to interact with polar molecules. The partial charge allows polar molecules to dissolve in water.
yes
Yes, polar proteins are typically water-soluble because water is a polar solvent that can interact with the polar regions of proteins through hydrogen bonding and electrostatic interactions. This allows for the proteins to dissolve and interact with water molecules.
