Why is solid water (ice) less dense than liquid water?

The hydrogen bonds between water molecules are spaced out.

Liquid water does not form hydrogen bonds.

It is actually more dense.

Hydrogen bonds are not able to be formed.

Water's ability to move against gravity in a narrow space, such as a tube, is called:

A redox reaction can easily be explained as:

transferring electrons between reactants

forming a bond by sharing electrons

the breakdown of glucose in cells

The reactant in a redox reaction that readily donates electrons is called a/an:

reducing agent

coenzyme

redox agent

All of the following statements are true about lipids, EXCEPT that _____.

all lipids are fats

lipids are good at storing energy

lipids are biological molecules that are insoluble in water

Why does soap remove grease from pans when we wash dishes?

Part of the soap is polar and part is non-polar

Soap molecules react with fats to break up fat blobs.

Soap sends a chemical message to fats to break up fat blobs

The whole soap molecule is non-polar, so it breaks apart fat
