Answer:
Multicellular eukaryotes evolved from unicellular prokaryotes by the process of endosymbiosis
Explanation:
All living beings have evolved from three groups of animals closely related with each other.Domains: Archaea,bacteria and eukarya.the archaea and bacteria are unicellular organism surrounded by single cell water and and coiled stand of DNA. Eukaryotic cells are more complex and with a linear strand of DNA which is in the nucleus. Actually mitochondria which had evolved from a free living bacterium which was swallowed by another cell. The host cell benefited from the chemical energy that mitochondria produced and mitochondria in turn is benefited to be inside the protected environment. Mitochondria is the main organelle which the multicellular eukaryotes with unicellular prokaryotes.
Answer: i would say the answer is D
Explanation: srry if i got it wrong
"Ammonification" is NOT a process that drives the carbon cycle.
<u>Option: B</u>
<u>Explanation:</u>
The organisms circulate carbon-di-oxide in carbon cycle by going through respiration, decomposition, sedimentation, and photosynthesis process but not ammonification. Basically the actual source of nitrogen is agricultural, when a plant or animal passes or an animal disperses waste.
In the remains, bacteria or fungi turn the organic nitrogen back into ammonium, a cycle called ammonisation or mineralisation. Then the micro-organisms generate metabolically required energy from organic nitrogen oxidation into ammonium. Ammonium is then essential for assimilation and absorption into amino acids or for use in other metabolic applications.
