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.
Nitrogen is part of the chlorophyll molecule, which gives plants their green color and is involved in creating food for the plant through photosynthesis. Lack of nitrogen shows up as general yellowing (chlorosis) of the plant. Because nitrogen can move around in the plant, older growth often yellows more than the new growth. Phosphorus is involved in the metabolic processes responsible for transferring energy from one point to another in the plant.
