Answer the following question given this paragraph: One type of radioactivity is alpha emission. What is an alpha particle? What happens to an alpha particle after it is emitted from an unstable nucleus?. Q: Alpha emission is a type of what? Choices: - radiation - heat - light - radioactivity A:
radioactivity
Q: Answer the following question given this paragraph: We can also consider the reverse reaction in the above equation. In that reaction, the ammonium ion donates a proton to the hydroxide ion. The ammonium ion is a Brnsted-Lowry acid, while the hydroxide ion is a Brnsted-Lowry base. Most Brnsted-Lowry acid-base reactions can be analyzed in this way. There is one acid and one base as reactants, and one acid and one base as products. Q: The ammonium ion is what type of acid? Choices: - normal -lowry - kaon - lowry - oxidized - lowry - brnsted-lowry A:
A: brnsted-lowry
Question: Answer the following question given this paragraph: Producers create food energy. They are the base of all life on Earth. Most producers use photosynthesis but a very small number use chemosynthesis. Q: What is the sun classified as on the main sequence? Choices: - shrinking star - red dwarf - gas giant - yellow dwarf A:
Answer: yellow dwarf

**Answer**
cloaca
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:
oxygen toxicity
