Q: Where in the lungs does gas exchange between the air and blood takes place? Read this paragraph and choose the correct option from the provided answers: The alveoli in the lungs are where gas exchange between the air and blood takes place. Each alveolus is surrounded by a network of capillaries. When you inhale, air in the alveoli has a greater concentration of oxygen than does blood in the capillaries. The difference in oxygen concentration causes oxygen to diffuse from the air into the blood. You can see how this occurs in Figure below . Choices: - ganglion - left lobe - bronchial tube - alveoli A:
alveoli

Ques: Q: What kind of metals have perplexing patterns of electron distribution that don't always follow the electron filling rules? Read this paragraph and choose the correct option from the provided answers: The transition metals are an interesting and challenging group of elements. They have perplexing patterns of electron distribution that don't always follow the electron filling rules. Predicting how they will form ions is also not always obvious. Choices: - solution - transformation - variating - transition A:
Ans: transition

Ques:Q: The wrist and base of the hand are formed by what series of small bones arranged in distal and proximal rows? Read this paragraph and choose the correct option from the provided answers: Carpal Bones The wrist and base of the hand are formed by a series of eight small carpal bones (see Figure 8.7). The carpal bones are arranged in two rows, forming a proximal row of four carpal bones and a distal row of four carpal bones. The bones in the proximal row, running from the lateral (thumb) side to the medial side, are the scaphoid ("boat-shaped"), lunate ("moonshaped"), triquetrum ("three-cornered"), and pisiform ("pea-shaped") bones. The small, rounded pisiform bone articulates with the anterior surface of the triquetrum bone. The pisiform thus projects anteriorly, where it forms the bony bump that can be felt at the medial base of your hand. The distal bones (lateral to medial) are the trapezium ("table"), trapezoid ("resembles a table"), capitate ("head-shaped"), and hamate ("hooked bone") bones. The hamate bone is characterized by a prominent bony extension on its anterior side called the hook of the hamate bone. A helpful mnemonic for remembering the arrangement of the carpal bones is "So Long To Pinky, Here Comes The Thumb. " This mnemonic starts on the lateral side and names the proximal bones from lateral to medial (scaphoid, lunate, triquetrum, pisiform), then makes a U-turn to name the distal bones from medial to lateral (hamate, capitate, trapezoid, trapezium). Thus, it starts and finishes on the lateral side. Choices: - ribs - patella - cranial - carpal A:

Ans:carpal

Ques: Q: Mountain building and earthquakes are some of the responses of rocks when subected to what? Read this paragraph and choose the correct option from the provided answers: When plates are pushed or pulled, the rock is subjected to stress. Stress can cause a rock to change shape or to break. When a rock bends without breaking, it folds. When the rock breaks, it fractures. Mountain building and earthquakes are some of the responses rocks have to stress. Choices: - time - erosion - weather - stress A:
Ans:
stress
