Answer the following question given this paragraph: The internal carotid artery enters the cranium through the carotid canal in the temporal bone. A second set of vessels that supply the CNS are the vertebral arteries, which are protected as they pass through the neck region by the transverse foramina of the cervical vertebrae. The vertebral arteries enter the cranium through the foramen magnum of the occipital bone. Branches off the left and right vertebral arteries merge into the anterior spinal artery supplying the anterior aspect of the spinal cord, found along the anterior median fissure. The two vertebral arteries then merge into the basilar artery, which gives rise to branches to the brain stem and cerebellum. The left and right internal carotid arteries and branches of the basilar artery all become the circle of Willis, a confluence of arteries that can maintain perfusion of the brain even if narrowing or a blockage limits flow through one part (Figure 13.15). Q: Which artery enters the cranium through the carotid canal in the temporal bone? Choices: - atrial artery - external carotid - venal artery - internal carotid artery A:
internal carotid artery
Answer the following question given this paragraph: Q: What is used to date older fossils? Choices: - search engines - litmus testing - electron microscopes - radioactive isotopes A:
radioactive isotopes
Q: Answer the following question given this paragraph: A storm is an episode of severe weather caused by a major disturbance in the atmosphere. Storms can vary a lot in the time they last and in how severe they are. A storm may last for less than an hour or for more than a week. It may affect just a few square kilometers or thousands. Some storms are harmless and some are disastrous. The size and strength of a storm depends on the amount of energy in the atmosphere. Greater differences in temperature and air pressure produce stronger storms. Types of storms include thunderstorms, tornadoes, hurricanes, and winter storms such as blizzards. Q: A winter storm is called what? Choices: - snow storm - tempest - gale - blizzard A:
A: blizzard
Question: Answer the following question given this paragraph: The color of soil indicates its fertility. Black or dark brown soils are rich in nitrogen and contain a high percentage of organic materials. Soils that are nitrogen poor and low in organic material might be gray, yellow, or red ( Figure below ). Soil with low organic material is not good for growing plants. Q: What does the color of soil indicate? Choices: - temperature - chemical makeup - density - fertility A:
Answer: fertility

Q: Answer the following question given this paragraph: Scientific investigations involve the collection of data through observation, the formation and testing of hypotheses by experimentation, and analysis of the results that involves reasoning. Scientific investigations begin with observations that lead to questions. Q: What is the initial stage of scienetific investigations? Choices: - asking questions - forming hypothesis - making predictions - observation A:
A: observation
