Answer the following question given this paragraph: Four interactions stabilize the tertiary structure of a protein: (a) ionic bonding, (b) hydrogen bonding, (c) disulfide linkages, and (d) dispersion forces. When a protein contains more than one polypeptide chain, each chain is called asubunit. The arrangement of multiple subunits represents a fourth level of structure, the quaternary structure of a protein. Hemoglobin, with four polypeptide chains or subunits, is the most frequently cited example of a protein having quaternary structure Saylor URL: http://www. saylor. org/books.

OPTIONS:
- binary
- unary
- ternary
- quaternary

Answer: quaternary

Answer the following question given this paragraph: The nitrogen atom of a primary amine is bonded to two hydrogen atoms and one carbon. The nitrogen atom of a secondary amine is bonded to one hydrogen and two carbons. The nitrogen atom of a tertiary amine is bonded to three carbon atoms. Amines are typically named by a common system rather than by IUPAC guidelines. The common system for naming amines along with several examples is shown below. Q: How many hydrogen atoms does a nitrogen atom of a primary amine have? A:
****
A: two

Answer the following question given this paragraph: In any chemical reaction, there is no overall change in the amount of energy. Energy cannot be created or destroyed. This is the law of conservation of energy. Q: What law states that energy cannot be created or destroyed? A:
OPTIONS:
- deposit of energy
- conservation of force
- difference of energy
- conservation of energy
conservation of energy

Answer the following question given this paragraph: Cerebral Cortex Compared to other vertebrates, mammals have exceptionally large brains for their body size. An entire alligator's brain, for example, would fill about one and a half teaspoons. This increase in brain to body size ratio is especially pronounced in apes, whales, and dolphins. While this increase in overall brain size doubtlessly played a role in the evolution of complex behaviors unique to mammals, it does not tell the whole story. Scientists have found a relationship between the relatively high surface area of the cortex and the intelligence and complex social behaviors exhibited by some mammals. This increased surface area is due, in part, to increased folding of the cortical sheet (more sulci and gyri). For example, a rat cortex is very smooth with very few sulci and gyri. Cat and sheep cortices have more sulci and gyri. Chimps, humans, and dolphins have even more. Q: What organ do mammals have that is exceptionally large for their body size? A:
OPTIONS:
- lungs
- heart
- liver
- brain

Answer:
brain
