Which of the following best describes a mass of essentially normal cells? benign tumor
oncogenes
carcinogens
malignant tumor
pls help me

The correct answer is most likely benign tumor

Explanation:

By elimination:

Oncogenes are genes, not a mass of cells, so this cannot be the correct answer.

Carcinogens are cancer causing agents, so again, not a mass of cells.

A malignant tumor is a tumor that can spread to other tissues, and is therefore not normal cells.

Benign tumor is the only remaining choice :).

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.
