Which is most likely to change with new discoveries and technologies?

Explanation:

Whatever has been fixed after centuries of discoveries cannot be changed simply with new inventions and discoveries, and only an addition can be facilitated with the existing system, if possible.

Therefore, the taxonomical levels of the organisms will change with time, as soon as more organisms will come up into existence. Hence, the taxonomical levels would change for sure, as new inventions would come up.

answer; ///(b) it is composed of four protein chains and four heme groups;

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.
