Q: Answer the following question given this paragraph: Cardiovascular System: Arteriosclerosis Compliance allows an artery to expand when blood is pumped through it from the heart, and then to recoil after the surge has passed. This helps promote blood flow. In arteriosclerosis, compliance is reduced, and pressure and resistance within the vessel increase. This is a leading cause of hypertension and coronary heart disease, as it causes the heart to work harder to generate a pressure great enough to overcome the resistance. Arteriosclerosis begins with injury to the endothelium of an artery, which may be caused by irritation from high blood glucose, infection, tobacco use, excessive blood lipids, and other factors. Artery walls that are constantly stressed by blood flowing at high pressure are also more likely to be injuredwhich means that hypertension can promote arteriosclerosis, as well as result from it. Recall that tissue injury causes inflammation. As inflammation spreads into the artery wall, it weakens and scars it, leaving it stiff (sclerotic). As a result, compliance is reduced. Moreover, circulating triglycerides and cholesterol can seep between the damaged lining cells and become trapped within the artery wall, where they are frequently joined by leukocytes, calcium, and cellular debris. Eventually, this buildup, called plaque, can narrow arteries enough to impair blood flow. The term for this condition, atherosclerosis (athero- = "porridge") describes the mealy deposits (Figure 20.14). Q: The heart and the arteries and veins are associated with what system of the body? A:
Answer: cardiovascular

Problem:OPTIONS:
- gold
- precipitation

- heat

Answer the following question given this paragraph: The enthalpy of the reactants is greater than the enthalpy of the products. During the course of the reaction, heat is released to the surroundings. Q: What is released during an enthalpy reaction? A:
****
A: heat

Answer the following question given this paragraph: rates The rates at which reactants are consumed and products are formed during chemical reactions vary greatly. We can identify five factors that affect the rates of chemical reactions: the chemical nature of the reacting substances, the state of subdivision (one large lump versus many small particles) of the reactants, the temperature of the reactants, the concentration of the reactants, and the presence of a catalyst. Q: The presence of what, which acts as a trigger, affects the rate of chemical reaction? A:
OPTIONS:
- friction
- heat
- light
- catalyst
catalyst

Answer the following question given this paragraph: Mars has two moons that are thought to be captured asteroids. Q: What are mars' moons thought to be? A:
OPTIONS:
- guerrillas asteroids
- new asteriods
- common asteriods
- captured asteroids

Answer: captured asteroids

Question: Answer the following question given this paragraph: Animal Cells versus Plant Cells At this point, you know that each eukaryotic cell has a plasma membrane, cytoplasm, a nucleus, ribosomes, mitochondria, peroxisomes, and in some, vacuoles, but there are some striking differences between animal and plant cells. While both animal and plant cells have microtubule organizing centers (MTOCs), animal cells also have centrioles associated with the MTOC: a complex called the centrosome. Animal cells each have a centrosome and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, whereas animal cells do not. The Centrosome The centrosome is a microtubule-organizing center found near the nuclei of animal cells. It contains a pair of centrioles, two structures that lie perpendicular to each other ( Figure 4.15). Each centriole is a cylinder of nine triplets of microtubules. Q: What is the microtubule-organizing center found near the nuclei of animal cells? A:
OPTIONS:
- lysosome
- spliceosome
- entrosome
- centrosome
Answer: centrosome

input: OPTIONS:
- oxidation
- photosynthesis
- condensation
- evaporation Now, answer this question: Answer the following question given this paragraph: Evaporation occurs when water on the surface changes to water vapor. The sun heats the water and gives water molecules enough energy to escape into the atmosphere. Q: What occurs when water on the surface changes to water vapor? A:
A:
output:
evaporation
