• Nucleic Acids

• Nucleotide

• Protein

• Amino acid

• Lipids

• Monosaccharides

• Carbohydrates

A sugar, phosphate and a nitrogenous base form building blocks for

• Carbohydrates

• Lipids

• Proteins

• Nucleic Acids

Why can't fatty acids dissolve in water?

• because they have to be heated

• because they are polar

• because they are nonpolar

Water is considered a universal solvent because it

• is a polar solvent that can dissolve many substances.
• is a non-polar solvent that cannot dissolve any substances.
• is only effective in dissolving gases.
• is a solid at room temperature and does not dissolve anything.

Large bodies of water do not fluctuate in temperature due to

• water's adhesive properties.

• water being nonpolar.

• water's cohesive nature.

• water's high specific heat capacity.

Match the water property to its action

• water moves from roots to leaves

• Capillary action

• water sticks to water

• Ice floats

• water sticks to other molecules

• Cohesion

• ice is less dense than water

• Adhesion

• water has uneven charges

• Polarity

Enzymes affect the ____ of a chemical reaction.

• concentration
• temperature
• pressure
• rate

Needs the right temperature and pH to function properly.

• Enzymes
• Lipids
• Carbohydrates
• Proteins

When you see a word ending in -ose, like fructose, lactose, galactose

you should think (check all that apply)

• carbohydrates

• sugars

• monosaccharide

  (1 sugar)

• polysaccaride

  (many sugars)
