Answer the following question given this paragraph: The body's second line of defense against pathogens includes the inflammatory response. If bacteria enter the skin through a scrape, the area may become red, warm, and painful. These are signs of inflammation. Inflammation is one way the body reacts to infections or injuries. Inflammation is caused by chemicals that are released when skin or other tissues are damaged. The chemicals cause nearby blood vessels to dilate, or expand. This increases blood flow to the damaged area, which makes the area red and slightly warm. The chemicals also attract white blood cells called neutrophils to the wound and cause them to leak out of blood vessels into the damaged tissue. Q: The body's second line of defense against pathogens includes which response? Choices: - reaction - anxiety - blood - inflammatory A:
inflammatory
Q: 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:
A: oxygen toxicity
Question: Answer the following question given this paragraph: Air movement takes place in the troposphere. Air moves because of differences in heating. The differences create convection currents and winds. Q: What is the primary cause of air movement in the troposphere? Choices: - solar winds - asteroids - the ozone layer - differences in heating A:
Answer: differences in heating
