Those are glucose, oxygen and carbon dioxide (CO2). <span>Respiration and photosynthesis are opposite processes in the plant cell. Photosynthesis makes the glucose and releases oxygen and they are used in cellular respiration to make ATP. The glucose is broken down during the respiration into CO2, which is used in photosynthesis. While H2O is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form H2O. </span>
Pollution plays a huge factor. With factories in demand, more and more substances are being released into Earth's atmosphere, resulting in higher temperatures.
Chronic bronchitis might lead to other diseases because it weakens your immune system and makes it easier to catch diseases and harder to fight them off.
