Answer the following question given this paragraph: 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. Q: The radial artery and which artery parallel their namesake bones, giving off smaller branches until they reach the wrist, or carpal region? Choices: - triceps - humerus - biceps - ulnar A:
ulnar

Answer the following question given this paragraph: Figure 40.5 The cells and cellular components of human blood are shown. Red blood cells deliver oxygen to the cells and remove carbon dioxide. White blood cellsincluding neutrophils, monocytes, lymphocytes, eosinophils, and basophilsare involved in the immune response. Platelets form clots that prevent blood loss after injury. Q: Neutrophils and lymphocytes are examples of what type of cell? Choices: - skin cell - red blood cell - Osteoclast - white blood cell A:
(Answer)
white blood cell
Ques: Answer the following question given this paragraph: because of interactions between the electrons of the outermost shell of different atoms, called the valence shell electrons. Electrons in inner shells are called core electrons. Elements are grouped together by similar chemical properties into a chart called the periodic table. Vertical columns of elements are called groups or families. Some of the groups of elements have names, like the alkali metals, the alkaline earth metals, the halogens, and the noble gases. A horizontal row of elements is called a period. Periods and groups have differing numbers of elements in them. The periodic table separates elements into metals, nonmetals, andsemimetals. The periodic table is also separated into main group elements,transition metals, lanthanide elements, and actinide elements. The lanthanide and actinide elements are also referred to as inner transition metal elements. The shape of the periodic table reflects the sequential filling of shells and subshells in atoms. The periodic table helps us understand trends in some of the properties of atoms. One such property is the atomic radius of atoms. From top to bottom of the periodic table, atoms get bigger because electrons are occupying larger and bigger shells. From left to right across the periodic table, electrons are filling the same shell but are being attracted by an increasing positive charge from the nucleus, and thus the atoms get smaller. Q: Electrons in inner shells are called what? Choices: - inner electrons - surface electrons - valence electrons - core electrons A:
Ans: core electrons

Answer the following question given this paragraph: Muscles work together in pairs to bend or straighten the joint. Q: What work together in pairs to bend or straighten a joint? Choices: - nerve fibers - collagen bands - cartilage tissues - muscles A:
(A).
muscles
Ques:Answer the following question given this paragraph: Bacteria are so small that they can only be seen with a microscope. When viewed under the microscope, they have three distinct shapes ( Figure below ). Bacteria can be identified and classified by their shape:. Q: How are bacteria identified and classified? Choices: - by there movement - by their color - by there cell count - by their shape A:

Ans:by their shape
Ques: Answer the following question given this paragraph: Many compounds form molecules, but ionic compounds form crystals instead. A crystal consists of many alternating positive and negative ions bonded together in a matrix. Look at the crystal of sodium chloride (NaCl) in the Figure below . The sodium and chloride ions are attracted to each other because they are oppositely charged, so they form ionic bonds. Q: What type of compounds can form crystals? Choices: - integral compounds - magnetic compounds - molecular compounds - ionic compounds A:
Ans:
ionic compounds
