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 essential for the growth of leaves and stems, and it helps to give plants a rich, green color. If it is lacking, plants will be pale and sickly-looking, and the oldest leaves will look worse than the newer ones.
Bacteria fixes nitrogen in the soil, converting it into compounds useful (and neccessary) to plant survival. Generally bacteria take N2 and convert it into nitrates and ammonia, which are important nutrients for plants. tlb AU Â· 8 years ago.
