4) Bacteria cells can be used to produce insulin for the treatment of diabetes in humans. Which best explains how the bacteria cells are able to
produce insulin for humans? *
The bacteria have been grown on a petri dish containing insulin.
The bacteria have been genetically engineered to contain the DNA needed to produce
insulin.
The bacteria have been exposed to radioactivity to create mutant strains capable of
producing insulin
The bacteria have been grown on a petri dish containing sugar; the bacteria produce
insulin in response to the 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.

the generally accepted parts of modern cell theory include: all known living things are made up of one or more cells. all living cells arise from pre-existing cells by division. the cell is the fundamental unit of structure and function in all living organisms.
