Problem:OPTIONS:
- oxygen
- calcium
- ions
- ph

Answer the following question given this paragraph: pH Regulation Recall that enzymes lose their three-dimensional conformation and, therefore, their function if the pH is too acidic or basic. This loss of conformation may be a consequence of the breaking of hydrogen bonds. Move the pH away from the optimum for a specific enzyme and you may severely hamper its function throughout the body, including hormone binding, central nervous system signaling, or myocardial contraction. Proper kidney function is essential for pH homeostasis. Q: Proper kidney function is essential for homeostasis of what level, which in turn helps ensure the functioning of enzymes? A:
****
A: ph

Answer the following question given this paragraph: There are two basic types of pollutants in air. They are known as primary pollutants and secondary pollutants. Q: What are two basic types of pollutants in the air? A:
OPTIONS:
- smog and coal
- organic and inorganic
- pesticides and smog
- primary and secondary pollutants
primary and secondary pollutants

Answer the following question given this paragraph: Moving water has energy ( Figure above ). That energy is used to make electricity. Hydroelectric power , or hydropower, harnesses the energy of water moving down a stream. Hydropower is the most widely used form of renewable energy in the world. This abundant energy source provides almost one fifth of the world's electricity. The energy of waves and tides can also be used to produce water power. At this time, wave and tidal power are rare. Q: What is the most widely used form of renewable energy in the world? A:
OPTIONS:
- wind
- fossil fuel
- solar
- hydropower

Answer: hydropower

Question: Answer the following question given this paragraph: 24.7 Nutrition and Diet Nutrition and diet affect your metabolism. More energy is required to break down fats and proteins than carbohydrates; however, all excess calories that are ingested will be stored as fat in the body. On average, a person requires 1500 to 2000 calories for normal daily activity, although routine exercise will increase that amount. If you ingest more than that, the remainder is stored for later use. Conversely, if you ingest less than that, the energy stores in your body will be depleted. Both the quantity and quality of the food you eat affect your metabolism and can affect your overall health. Eating too much or too little can result in serious medical conditions, including cardiovascular disease, cancer, and diabetes. Vitamins and minerals are essential parts of the diet. They are needed for the proper function of metabolic pathways in the body. Vitamins are not stored in the body, so they must be obtained from the diet or synthesized from precursors available in the diet. Minerals are also obtained from the diet, but they are also stored, primarily in skeletal tissues. Q: Nutrition and diet affect your metabolism. more energy is required to break down fats and proteins than this? A:
OPTIONS:
- vitamins
- electrolytes
- minerals
- carbohydrates
Answer: carbohydrates

input with options: Answer the following question given this paragraph: The marsupial embryo is nourished inside the uterus with food from a yolk sac instead of through a placenta. The yolk sac stores enough food for the short period of time the embryo remains in the uterus. After the embryo is born, it moves into the mother's pouch, where it clings to a nipple. It remains inside the pouch for several months while it continues to grow and develop. Even after the offspring is big enough to leave the pouch, it may often return to the pouch for warmth and nourishment. Eventually, the offspring is mature enough to remain outside the pouch on its own. Q: The marsupial embryo is nourished inside the uterus with food from a yolk sac instead of through a what? A:
OPTIONS:
- stomach
- ovum
- umbilical cord
- placenta
output: placenta

Problem: OPTIONS:
- nitric acid
- residual acid
- excessive acid
- lactic acid
Q: Answer the following question given this paragraph: Animals and some bacteria and fungi carry out lactic acid fermentation. Lactic acid is a waste product of this process. Our muscles perform lactic acid fermentation during strenuous exercise, since oxygen cannot be delivered to the muscles quickly enough. The buildup of lactic acid is believed to make your muscles sore after exercise. Bacteria that produce lactic acid are used to make cheese and yogurt. The lactic acid causes the proteins in milk to thicken. Lactic acid also causes tooth decay, because bacteria use the sugars in your mouth for energy. Q: During strenuous exercise our muscles perform what kind of fermentation? A:
Answer:
lactic acid
