Answer the following question given this paragraph: Conduction is the transfer of thermal energy between particles of matter that are touching. Thermal conduction occurs when particles of warmer matter bump into particles of cooler matter and transfer some of their thermal energy to the cooler particles. Conduction is usually faster in certain solids and liquids than in gases. Materials that are good conductors of thermal energy are called thermal conductors . Metals are especially good thermal conductors because they have freely moving electrons that can transfer thermal energy quickly and easily. Q: What is the name for the transfer of thermal energy between particles of matter that are touching? Choices: - activation - induction - convection - conduction A:
conduction
Answer the following question given this paragraph: Negatively charged and has a very small mass compared to the mass of other subatomic particles. Electrons were initially called cathode rays. Q: What were the electrons initially called? Choices: - gamma rays - plasma rays - polymer rays - cathode rays A:
cathode rays
Q: 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:
A: internal carotid artery
Question: Answer the following question given this paragraph: Linked genes are genes that are close together on the same chromosome. Linked genes are inherited together. Q: What are genes that are close together on the same chromosome called? Choices: - mutated genes - infected genes - stored genes - linked genes A:
Answer: linked genes

Answer the following question given this paragraph: Core electrons are the electrons that are closer to the nucleus and therefore do not participate in bonding. Q: What is the name for electrons closer to the nucleus that do not participate in bonding? Choices: - surface electrons - radical electrons - odd electrons - core electrons A:
**Answer**
core electrons

Answer the following question given this paragraph: The mass number is the number of protons plus the number of neutrons in an atom. For example, most atoms of helium have 2 neutrons, so their mass number is 2 + 2 = 4. This mass number means that an atom of helium has a mass of about 4 amu. Q: What makes up the mass number of an atom? Choices: - electrons and neutrons - atoms and neutrons - molecules and electrons - protons and neutrons A:
(Answer)
protons and neutrons
