The synthesis of thyroid hormones requires the iodination of tyrosine molecules and the combination of two iodinated tyrosine residues
Archaea means ancient, bacteria are, well, minuscule organisms that live everywhere, and eukarya are organisms with cells that have a nucleus as well as membrane-bound organelles... my best guess if it is planets you mean, then the answer would be archaea, if it is plants, like flowers or such, then it is eukarya.
I hope this helps!
Answer:
1. Atmosphere and ecosystem
2. Carbon/CO2 is absorbed by the plants and then released as oxygen.
3. Carbon is used in the cellular respiration process to make ATP.
4. Decomposers break down dead material and release CO2 in that process into the atmosphere for plants to use that carbon for photosynthesis again.
