Determining the weight of 100 CDs depends on whether only the CDs are weighed or if the CDs have sleeves or jewel cases. A single CD by itself weighs about 0.58 ounces. Therefore, 100 CDs by themselves weigh 58 ounces.
Nitrogen is found in all living cells. Without nitrates, a plant cannot grow and produce flowers and seeds. This is primarily because nitrogen is an essential component of plant proteins and chlorophyll, which is necessary for the process of photosynthesis. Photosynthesis is how a plant makes food. Without nitrates, photosynthesis cannot occur, and the plant will die from a lack of food.
The carbon in these mineral deposits remains locked up until it is released to the atmosphere as carbon dioxide when fossil fuels are extracted and burned. Nitrogen Cycle: Organisms require nitrogen in various chemical forms to make proteins and genetically important nucleic acids such as DNA. Klost green plants need nitrogen in the form of nitrate ions (NO,-) and ammonium ions (NH4 +).
