Regarding the structure of dna, the covalently arranged combination of a deoxyribose and a nitrogenous base would be called a(n)

The DNA has a double helical structure, which is made up of the molecules known as the nucleotides. Each of these nucleotide molecule is composed of the deoyribose sugar, phosphate group, and a nitrogenous base. The nitrogenous bases are of two types, namely the purines, and pyrimidines. The deoxyribose sugar and the nitrogenous base bonded covalently would be known as nucleoside-nitrogenous base + sugar.

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
