Q: Compared to thoracic and lumbar types, the cervical type of what structures carry the least amount of body weight? Read this paragraph and choose the correct option from the provided answers: Cervical Vertebrae Typical cervical vertebrae, such as C4 or C5, have several characteristic features that differentiate them from thoracic or lumbar vertebrae (Figure 7.25). Cervical vertebrae have a small body, reflecting the fact that they carry the least amount of body weight. Cervical vertebrae usually have a bifid (Y-shaped) spinous process. The spinous processes of the C3C6 vertebrae are short, but the spine of C7 is much longer. You can find these vertebrae by running your finger down the midline of the posterior neck until you encounter the prominent C7 spine located at the base of the neck. The transverse processes of the cervical vertebrae are sharply curved (U-shaped) to allow for passage of the cervical spinal nerves. Each transverse process also has an opening called the transverse foramen. An important artery that supplies the brain ascends up the neck by passing through these openings. The superior and inferior articular processes of the cervical vertebrae are flattened and largely face upward or downward, respectively. The first and second cervical vertebrae are further modified, giving each a distinctive appearance. The first cervical (C1) vertebra is also called the atlas, because this is the vertebra that supports the skull on top of the vertebral column (in Greek mythology, Atlas was the god who supported the heavens on his shoulders). The C1 vertebra does not have a body or spinous process. Instead, it is ring-shaped, consisting of an anterior arch and a posterior arch. The transverse processes of the atlas are longer and extend more laterally than do the transverse processes of any other cervical vertebrae. The superior articular processes face upward and are deeply curved for articulation with the occipital condyles on the base of the skull. The inferior articular processes are flat and face downward to join with the superior articular processes of the C2 vertebra. The second cervical (C2) vertebra is called the axis, because it serves as the axis for rotation when turning the head... Choices: - nasal - nuclei - ametic - vertebrae A:
vertebrae

Q: In celsius, what is the boiling point of water? Read this paragraph and choose the correct option from the provided answers: The crystal structure of ionic compounds is strong and rigid. It takes a lot of energy to break all those ionic bonds. As a result, ionic compounds are solids with high melting and boiling points. You can see the melting and boiling points of several different ionic compounds in the Table below . To appreciate how high they are, consider that the melting and boiling points of water, which is not an ionic compound, are 0C and 100C, respectively. Choices: - zero degrees - two hundred twelve degrees - ninety eight degrees - one hundred degrees A:
one hundred degrees

Q: Q: What are the narrowest blood vessels, where oxygen is transferred into body cells? Read this paragraph and choose the correct option from the provided answers: Red blood cells are flat, round, and very small. Their small size allows easy maneuverability through the capillaries, the narrowest blood vessels, where oxygen is transferred into body cells. Choices: - arteries - muscles - viens - capillaries A:
A: capillaries

Question: Q: What drives the turbine in a thermonuclear reactor? Read this paragraph and choose the correct option from the provided answers: Scientists are searching for ways to create controlled nuclear fusion reactions on Earth. Their goal is develop nuclear fusion power plants, where the energy from fusion of hydrogen nuclei can be converted to electricity. You can see how this might work in the Figure below . In the thermonuclear reactor, radiation from fusion is used to heat water and produce steam. The steam can then be used to turn a turbine and generate electricity. Choices: - magnets - heated oil - wind energy - heated water or steam A:
Answer: heated water or steam

Q: An acellular, external cuticle protects the _________. Read this paragraph and choose the correct option from the provided answers: Anatomy The epidermis is protected by an acellular, external cuticle, but this is much thinner than the cuticle found in the ecdysozoans and does not require periodic shedding for growth. Circular as well as longitudinal muscles are located interior to the epidermis. Chitinous hairlike extensions, anchored in the epidermis and projecting from the cuticle, called setae/chaetae are present in every segment. Annelids show the presence of a true coelom, derived from embryonic mesoderm and protostomy. Choices: - dermis - lungs - stomach - epidermis A:
**Answer**
epidermis

Q: The oceans affect earth's atmosphere and influence its what? Read this paragraph and choose the correct option from the provided answers: Much of Earth's surface is covered with oceans. That's why Earth is called the "water planet. " Without all that water, Earth would be a very different place. The oceans affect Earth's atmosphere and influence its climate. An incredible diversity of living things inhabit the ocean as well. You might think that oceans have always covered Earth's surface, but you would be wrong!. Choices: - earthquakes - mountains - volcanoes - climate A:
**Answer**
climate
