Q: Answer the following question given this paragraph: Blood Vessels The blood from the heart is carried through the body by a complex network of blood vessels (Figure 16.12). Arteries take blood away from the heart. The main artery of the systemic circulation is the aorta; it branches into major arteries that take blood to different limbs and organs. The aorta and arteries near the heart have heavy but elastic walls that respond to and smooth out the pressure differences caused by the beating heart. Arteries farther away from the heart have more muscle tissue in their walls that can constrict to affect flow rates of blood. The major arteries diverge into minor arteries, and then smaller vessels called arterioles, to reach more deeply into the muscles and organs of the body. Arterioles diverge into capillary beds. Capillary beds contain a large number, 10's to 100's of capillaries that branch among the cells of the body. Capillaries are narrow-diameter tubes that can fit single red blood cells and are the sites for the exchange of nutrients, waste, and oxygen with tissues at the cellular level. Fluid also leaks from the blood into the interstitial space from the capillaries. The capillaries converge again into venules that connect to minor veins that finally connect to. Q: What is the main artery of the systematic circulation called? Choices: - femoral - subclavian - carotid - aorta A:
A: aorta

Q: Answer the following question given this paragraph: Did you ever make cupcakes from scratch? You mix together flour, sugar, eggs, and other ingredients to make the batter, put the batter into cupcake papers, and then put them into the oven to bake. The cupcakes that come out of the oven after baking are different from any of the individual ingredients that went into the batter. Like the ingredients that join together to make cupcakes, atoms of different elements can join together to form entirely different substances called compounds. In cupcakes, the eggs and other wet ingredients cause the dry ingredients to stick together. What causes elements to stick together in compounds? The answer is chemical bonds. Q: What is the substance called whenatoms of different elements join together? Choices: - crusts - crystals - plants - compounds A:
A: compounds

Q: Answer the following question given this paragraph: Four underlying principles form the basis of biology. They are cell theory, gene theory, homeostasis, and evolution. Q: How many underlying principles does the science of biology have? Choices: - five - three - eleven - four A:
A: four
