Two reasons: Aspirin has a direct potentially erosive effect on the stomach lining causing the lining to become inflamed , especially on an empty stomach and thus can contribute to creation or perpetuation of a breach in the stomach lining (an ulcer).
Photosynthesis is a process used by plants in which energy from sunlight is used to convert carbon dioxide and water into molecules needed for growth. These molecules include sugars, enzymes and chlorophyll.
You already know that plants need carbon dioxide, water and sunlight to make their food. You also know that the food they make is called glucose. In addition to glucose, plants also produce oxygen. This information can be written in a word equation as shown below.uring these reactions light energy is converted to chemical energy. 1  Chlorophyll and other pigments absorb energy from sunlight. 2  Water is used to provide electrons and hydrogen ions but also produces oxygen. 3  The electrons and hydrogen ions are used to create ATP and NADPH.
