James got sick with an infection called bronchitis. He coughed a lot and had trouble breathing. After a week, James started to feel better and could breathe more easily. James’ system was most harmed by the bronchitis, and his system helped him recover.

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).
