Which of the following formulas represents a disaccharide?
Disaccharides, such as maltose, are produced when two monosaccharides undergo a dehydration synthesis reaction.
Which of the following formulas represents a disaccharide?
The disaccharide maltose is formed by the dehydration synthesis reaction of two glucose monomers. When simply adding the two glucose monomers together, it may be thought that the summation of the two 
will be the chemical formula of maltose. However, this does not account for the dehydration synthesis reaction in which one oxygen atom and two hydrogen atoms disappear. After accounting for these molecules the chemical formula for maltose will be represented by

Animals and plants store glucose in saccharide polymers.
Which of the following is the polymer form of storage in plants and animals, respectively?
Animals and plants store glucose in saccharide polymers.
Which of the following is the polymer form of storage in plants and animals, respectively?
The sugar polymer form in which plants store energy is starch, whereas with animals, it is glycogen. While the other answers may in fact be sugar molecules involved in energy metabolism, they do not represent the primary sugar polymer storage molecule. Therefore the correct form of storage for plants is starch. And the correct form of storage for animals is glycogen.

What drives the formation of the phospholipid bilayer?
The phospholipid bilayer is critically important to the separation of the internal and external environment of the cell.
What drives the formation of the phospholipid bilayer?
The external hydrophilic environment attracts polar hydrophilic phosphate head groups to the exterior, while allowing non-polar hydrophobic fatty acids to remain shielded in the interior of what becomes the phospholipid bilayer.

Which of the following macromolecules are composed of long chains of amino acids?
Which of the following macromolecules are composed of long chains of amino acids?
By process of elimination, lipids and fats cannot be the correct answer-they are synonymous (lipids are also known as fats). Carbohydrates, eg sugars and starches are composed only of carbon, hydrogen, and oxygen. Nucleic acids contribute to DNA and RNA structure and function. The correct answer is proteins, made of long chains of amino acids-amino acids are sometimes called the "building blocks" of proteins.
