If you could analyze, at the molecular level, a plasma cell making IgE antibody, you would find which of the following:. A. A DNA sequence for V, D, J genes translocated near the Ce DNA exon
B. mRNA specific for either kappa or lambda light chains
C. DNA specific for both kappa and lambda light chains
D. mRNA specific for m chains
E. A DNA sequence coding for the T-cell receptor for antigen

A.  A DNA sequence for V,D, J genes translocated near the Ce DNA exon

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.

well for one plants are always the producer, so a is the answer. a wolf is more of the consumer(predator) and the deer is the prey so i know those two are out of the question. also mushrooms are fungi/fungus so a is the producer.
