Three domains of life are eukarya archae and bacteria. The prokaryotes are classified into the bacteria and archaea. Archaea lives in the extrem conditions like extreme temperature, cold and heat.
Archaea are more similar to eukarya as both of them contains histone proteins associated with DNA molecule. The archaea and eukarya contains introns in their structure. Methionine acts as the initiator in the process of translation both in archaea and eukarya. Different types of RNA polymerase is present in eukarya and archaea.
Thus, eukarya are more closely related to archaea.
The correct answer would be Archaea. So Eukarya are more closely related to Archaea.
Explanation:
Archaea has a morphological similarities with bacteria, but archaea possesses genes and several metabolic pathways that are more closely related to eukaryotes. A Eukarya have enzymes that are involved in transcriptions and translations. Now because archaea have more genes than that of Eukarya, so we can say that Eukarya are more closlely related to Archae.
Due to the fact that all the organisms are connected in a chain, the energy flow would be affected and that would result in many organisms being deprived of energy they need and that creates a chain effect.
