Which statement must be mentioned in explaining why amphipathic molecules line up at a water surface? which statement must be mentioned in explaining why amphipathic molecules line up at a water surface? nonpolar groups repel water. nonpolar groups attract one another.

Nonpolar groups repel water.

Explanation: Amphipathic molecules line up at a water surface because the polar end of each molecule remains in contact with water grouping together, while the nonpolar ends are grouped by repelling water.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
