Saturated fatty acids have triple bonds; unsaturated have double bonds.

Analyze how the structure of water contributes to its unique properties.

Water's bent structure and hydrogen bonding contribute to its high specific heat.

Water's linear structure allows it to be a good solvent.

Water's ionic structure allows it to dissolve salts.

Water's nonpolar structure makes it a good solvent for oils.

Evaluate the impact of temperature on enzyme activity.

Enzyme activity increases with temperature up to a point, then decreases.

Enzyme activity increases indefinitely with temperature.

Enzyme activity decreases with increasing temperature.

Temperature has no effect on enzyme activity.

What is the difference between DNA and RNA in terms of structure?

DNA is double-stranded; RNA is single-stranded.

DNA is single-stranded; RNA is double-stranded.

DNA contains uracil; RNA contains thymine.

DNA contains ribose sugar; RNA contains deoxyribose sugar.
