Q: The radial artery and which artery parallel their namesake bones, giving off smaller branches until they reach the wrist, or carpal region? Read this paragraph and choose the correct option from the provided answers: Arteries Serving the Upper Limbs As the subclavian artery exits the thorax into the axillary region, it is renamed the axillary artery. Although it does branch and supply blood to the region near the head of the humerus (via the humeral circumflex arteries), the majority of the vessel continues into the upper arm, or brachium, and becomes the brachial artery (Figure 20.31). The brachial artery supplies blood to much of the brachial region and divides at the elbow into several smaller branches, including the deep brachial arteries, which provide blood to the posterior surface of the arm, and the ulnar collateral arteries, which supply blood to the region of the elbow. As the brachial artery approaches the coronoid fossa, it bifurcates into the radial and ulnar arteries, which continue into the forearm, or antebrachium. The radial artery and ulnar artery parallel their namesake bones, giving off smaller branches until they reach the wrist, or carpal region. At this level, they fuse to form the superficial and deep palmar arches that supply blood to the hand, as well as the digital arteries that supply blood to the digits. Figure 20.32 shows the distribution of systemic arteries from the heart into the upper limb. Table 20.9 summarizes the arteries serving the upper limbs. Choices: - triceps - humerus - biceps - ulnar A:
ulnar

Q: What do some animals use to get a feel for their environment? Read this paragraph and choose the correct option from the provided answers: Choices: - neuroreceptors - nociceptors - fibroblasts - mechanoreceptors A:
(Answer)
mechanoreceptors

Ques: Q: What term given to animals like reptiles is a synonym for ectothermic, which means that their heat comes from their environment? Read this paragraph and choose the correct option from the provided answers: Reptiles cold-blooded, or ectothermic, meaning that their heat come from their environment. Sometimes defined as all amniotes that are not birds or mammals. Reptiles can be classified by skull structure into four groups: . Choices: - warm-blooded - hot-blooded - thermal regulating - cold-blooded A:
Ans: cold-blooded

Q: What is the process in which an atom becomes an ion known as? Read this paragraph and choose the correct option from the provided answers: The process in which an atom becomes an ion is called ionization. It may occur when atoms are exposed to high levels of radiation. The radiation may give their outer electrons enough energy to escape from the attraction of the positive nucleus. However, most ions form when atoms transfer electrons to or from other atoms or molecules. For example, sodium atoms may transfer electrons to chlorine atoms. This forms positive sodium ions (Na + ) and negative chloride ions (Cl - ). You can see an animation of this process at the URL below. Choices: - electrification - evaporation - oxidation - ionization A:
(A).
ionization

Ques:Q: Bones consist of four types of tissue, compact bone, spongy bone, bone marrow, and what? Read this paragraph and choose the correct option from the provided answers: Bones consist of four different types of tissue: periosteum, compact bone, spongy bone, and bone marrow. Ossification gradually changes the cartilage skeleton of the fetus to the bony skeleton of the adult. Choices: - collagen - epithelium - plasma - periosteum A:

Ans:periosteum

Q: Internal resistance, or (electrical) resistance in general, involves the resistance of the flow of what? Read this paragraph and choose the correct option from the provided answers: Internal Resistance As noted before, a 12-V truck battery is physically larger, contains more charge and energy, and can deliver a larger current than a 12-V motorcycle battery. Both are lead-acid batteries with identical emf, but, because of its size, the truck battery has a smaller internal resistance r . Internal resistance is the inherent resistance to the flow of current within the source itself. Figure 21.9 is a schematic representation of the two fundamental parts of any voltage source. The emf (represented by a script E in the figure) and internal resistance r are in series. The smaller the internal resistance for a given emf, the more current and the more power the source can supply. Choices: - protons - force - water - current A:
current
