Q: Answer the following question given this paragraph: General Structure of a Vertebra Within the different regions of the vertebral column, vertebrae vary in size and shape, but they all follow a similar structural pattern. A typical vertebra will consist of a body, a vertebral arch, and seven processes (Figure 7.23). The body is the anterior portion of each vertebra and is the part that supports the body weight. Because of this, the vertebral bodies progressively increase in size and thickness going down the vertebral column. The bodies of adjacent vertebrae are separated and strongly united by an intervertebral disc. The vertebral arch forms the posterior portion of each vertebra. It consists of four parts, the right and left pedicles and the right and left laminae. Each pedicle forms one of the lateral sides of the vertebral arch. The pedicles are anchored to the posterior side of the vertebral body. Each lamina forms part of the posterior roof of the vertebral arch. The large opening between the vertebral arch and body is the vertebral foramen, which contains the spinal cord. In the intact vertebral column, the vertebral foramina of all of the vertebrae align to form the vertebral (spinal) canal, which serves as the bony protection and passageway for the spinal cord down the back. When the vertebrae are aligned together in the vertebral column, notches in the margins of the pedicles of adjacent vertebrae together form an intervertebral foramen, the opening through which a spinal nerve exits from the vertebral column (Figure 7.24). Q: What separates and strongly unites bodies of adjacent vertebrae? Choices: - synovial fluid - collagen fibers - interstitial fluid - intervertebral disc A:
A: intervertebral disc

Q: Answer the following question given this paragraph: When appropriate, a symbol may be written above or below the arrow to indicate some special circumstance. The symbol "" is often used to indicate that the reaction is to be heated. Q: Which enzyme is used in step three of the polymerase chain reaction because of it's ability to withstand high temperatures? Choices: - minocycline polymerase - carbon polumerase - backronym polymerase - taq polymerase A:
A: taq polymerase

Q: Answer the following question given this paragraph: People themselves are also affected by the large size of the human population. Some people have a lot; some have very little. Many people refer to the abundance of luxury items in some people's lives as over-consumption . People in developed nations use 32 times more resources than people in the developing countries of the world. The symbol of this is CO 2 emissions, which are a waste product from fossil fuel burning. Populations that burn the most fossil fuels have a high standard of living. Q: What is a waste product from fossil fuel burning? Choices: - smog - oxidation - hydrogen gas - co2 emissions A:
A: co2 emissions

Q: Answer the following question given this paragraph: How do you think scientists test whether two populations are separate species? They bring species from two populations back together again. If the two populations do not mate and produce fertile offspring, they are separate species. Q: If two populations do not mate and produce fertile offspring, what results? Choices: - same species - large species - small species - separate species A:
A: separate species
