Question: Answer the following question given this paragraph: In summary, aerobic and anaerobic respiration each have advantages under specific conditions. Aerobic respiration produces far more ATP, but risks exposure to oxygen toxicity. Anaerobic respiration is less energy-efficient, but allows survival in habitats which lack oxygen. Within the human body, both are important to muscle function. Muscle cells specialized for aerobic respiration provide endurance, and those specialized for lactic acid fermentation support short but intense energy expenditures. Both ways of making ATP play critical roles in life on earth. Q: What exposure risk comes with aerobic respiration? Choices: - helium toxicity - carbon toxicity - nitrogen toxicity - oxygen toxicity A:
Answer: oxygen toxicity

Question: Answer the following question given this paragraph: An alkane is a hydrocarbon in which there are only single covalent bonds. The simplest alkane is methane, with the molecular formula CH 4 . The carbon is the central atom and makes four single covalent bonds to hydrogen atoms. Q: What is a hydrocarbon in which there are only single covalent bonds? Choices: - combined - proline - fullerene - alkane A:
Answer: alkane

Question: Answer the following question given this paragraph: Any unused energy in food, whether it comes from carbohydrates, proteins, or lipids, is stored in the body as fat. An extra 3,500 Calories of energy results in the storage of almost half a kilogram (1 pound) of stored body fat. People who consistently consume more food energy then they need may become obese. Obesity occurs when the body mass index is 30.0 kg/m 2 or greater. Body mass index (BMI) is an estimate of the fat content of the body. It is calculated by dividing a person's weight (in kilograms) by the square of the person's height (in meters). Obesity increases the risk of health problems such as type 2 diabetes and hypertension. Q: Any unused energy in food, whether it comes from carbohydrates, proteins, or lipids, is stored in the body where? Choices: - kidneys - spleen - bones - fat A:
Answer:
fat
