Answer the following question given this paragraph: Metatarsal Bones The anterior half of the foot is formed by the five metatarsal bones, which are located between the tarsal bones of the posterior foot and the phalanges of the toes (see Figure 8.19). These elongated bones are numbered 15, starting with the medial side of the foot. The first metatarsal bone is shorter and thicker than the others. The second metatarsal is the longest. The base of the metatarsal bone is the proximal end of each metatarsal bone. These articulate with the cuboid or cuneiform bones. The base of the fifth metatarsal has a large, lateral expansion that provides for muscle attachments. This expanded base of the fifth metatarsal can be felt as a bony bump at the midpoint along the lateral border of the foot. The expanded distal end of each metatarsal is the head of the metatarsal bone. Each metatarsal bone articulates with the proximal phalanx of a toe to form a metatarsophalangeal joint. The heads of the metatarsal bones also rest on the ground and form the ball (anterior end) of the foot. Q: The anterior half of the foot is formed by the five what type of bones? Choices: - malignancy bones - conidia bones - conidia bones - metatarsal bones A:
(Answer)
metatarsal bones
Ques: Answer the following question given this paragraph: Molecular formulas tell us how many atoms of each element are present in one molecule of a molecular compound. In many cases, the molecular formula is the same as the empirical formula. For example, the molecular formula of methane is CH 4 , and because 1:4 is the smallest whole-number ratio that can be written for this compound, that is also its empirical formula. Sometimes, however, the molecular formula is a simple whole-number multiple of the empirical formula. Acetic acid is an organic acid that gives vinegar its distinctive taste and smell. Its molecular formula is C 2 H 4 O 2 . Glucose is a simple sugar that cells use as their primary source of energy. Its molecular formula is C 6 H 12 O 6 . The structures of both molecules are shown in Figure below . They are very different compounds, yet both have the same empirical formula, CH 2 O. Q: What simple sugar is the cell's primary source of energy? Choices: - carbon - nicotine - chloride - glucose A:
Ans: glucose
