Question

what do fats, steroids, and waxes have in common? (a) moderate polarity. (b) low solubility in water. (c) they occur in membranes. both (a) and (c). both (b) and (c). part b dr. haxton told one of his students, to move in the bloodstream, fats need the help of phospholipids. what would a good student say? you have it backwards. fats help phospholipids to travel. sorry, dr. haxton! help comes from cholesterol, not phospholipids. not so. fats are small enough to travel easily without help. right. fats are too polar to travel alone in water. yes. nonpolar molecules arent compatible with water.

Explanation:

Fats, steroids, and waxes are lipids. Lipids are non - polar molecules, which gives them low solubility in water (a polar solvent). Fats need phospholipids to move in the bloodstream because fats are non - polar and water in the bloodstream is polar, so non - polar molecules aren't compatible with water.

Answer:

Part A: B. Low solubility in water.
Part B: Yes. Nonpolar molecules aren't compatible with water.
