are found especially in the mucous membrane, standing guard against parasites and allergens. Lymphocytes Basophils Neutrophils Eosinophils

The correct answer is D. Eosinophils

Explanation:

Eosinophils are a type of white cells, this means these cells are part of the immune system and protect the body from viruses, parasites, and other pathogens. Besides this, eosinophils differ from other white cells because they mainly attack parasites and allergens by eliminating nocive substances, reacting to allergens and regulating inflammation.

According to this, the eosinophils are the cells found in mucous membranes that react to parasites and allergens.

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.
