Body
Number each answer as Question 1, Question 2, et cetera but do not include the questions as part of the exam. Add each answer as a series of paragraphs with each paragraph separated by a vertical space between paragraphs. Use single spacing; do not double-space your answers to the questions. Do not use footnotes. Do not include illustrations or graphs. Do not include quotations. Your answers are to be narrative only and re-written in your own words. List only the five primary sources for all answers combined at the end of the exam; do not list sources at the end of each question, and do not use in-text citations.
The top of the first page of an exam will look something like this . . .

Question 1
Charles Darwin (1809-1882) is perhaps one of the most influential scientists of our time. All of his life he worked toward understanding the reason why species are so diverse and how animals and their ancestors developed over time. His theory of evolution was formed during his trip to the Galapagos Islands while aboard the ship the HMS Beagle.
Darwin studied animal husbandry upon returning to England. He was intersted in the selection of animals to improve the breed. He wondered whether the same selection by natural forces could lead to modification of animals in nature. If so, he hypothesized, the ancestors of the Galapagos finches could have, by chance, arrived on the islands and each island's characteristics, being different from the others, acted somehow to modify future generations of finches as does artificial selection act to improve a breed of domesticated animals. More . . . et cetera
Question 2
DNA structure comprises sequences of nucleotides, Adenine (A), Thymine (T), Guanine (G) and Cytosine (C), in two strands that wrap about one another in a helix. The two strands are held together by the attractions between nucleotides forming "base pairs": between A and T and between G and C. Changing these AT and GC base pairs is one type of mutation that can occur. Mutations include changes to individual nucleotides, duplicating or deleting regions of DNA, and changing the locations of regions of DNA.
Mutations can occur by a number of different processes. Radioactive minerals of Earth emit particles as those minerals decay over time. Some of these particles are harmless, not even able to penetrate the outer layers of skin. Other particles are able to pass through our bodies and as they do may strike our DNA molecules causing physical damage. High frequency, high energy electromagnetic radiation such as ultraviolet, X-ray and gamma-ray radiation can cause chemical changes as they are absorbed by DNA, making the DNA more chemically reactive. And, of course, DNA itself is a molecule that can react with other molecules and by so doing be changed in the course of the reaction. Radiation and chemicals that can cause damage to DNA are referred to as mutagens More . . . et cetera

References Style Guide
List only five sources in the References section: the textbook and an additional four resources that were most useful to you in constructing your answers to the exam questions. Alphabetize your references by the first author's last name.
Enter your References section two lines directly below the last answer of the examination.
Note: Do not include common, basic sources such as dictionaries. For encyclopedic sites such as Wikipedia or Encyclopedia Britannica, cite only once regardless of the number of pages or topics used. It is best to use sources from scholarly journals.

Question 3
The differences in electronegativity between hydrogen (2.1) and oxygen (3.5) causes the bonding electrons of the hydrogens to be drawn more strongly toward the oxygen nucleus (with an 8+ charge) than to the single proton (with a 1+ charge) that is the hydrogen nucleus.
Because of these polar covalent bonds between oxygen and hydrogen, the hydrogen poles of the molecule have a partial positive charge (d+) and the two filled orbitals of oxygen have partial negative (d-) charges. Water molecules thus behave as magnets with two positive poles and two negative poles and will be attracted to anything polar or with a charge . . . hydrogens attracted to negative areas, and oxygen's orbitals filled with electrons attracted to positive areas. More . . . et cetera
Question 4
Enzymes are fragile. Proteins have complex structures dependent on weak interactions between their various parts to become folded into very specific shapes. These shapes are essential to an enzyme's function because the various surfaces of the enzyme are important in recognizing the molecules on which they act and are reactive, participating in the chemical reactions with the substrate (the molecule on which an enzyme acts). Any change in shape influences the activity of the enzyme and a permanent change in shape and the destruction of enzyme activity can be due to temperatures which are too high. A permanent change in enzyme shape that inhibits its activity is called "denaturation". A good analogy is the heating of the protein white of an egg and its "denaturation" from a clear, viscous fluid to an opaque, white rubbery solid. This denaturation is irreversible . . . you cannot reverse this reaction to regain the fluid egg white. Over-heating causes denaturation of proteins and, in particular, the class of proteins that are enzymes are most sensitive. Therefore, during heat stoke the denaturation of structural proteins and enzymes is irreversible and even if normal temperatures are regained, the damage has been done. More . . . et cetera
