Answer:
Green plants and trees use photosynthesis to make food from sunlight, carbon dioxide and water in the atmosphere: It is their primary source of energy. The importance of photosynthesis in our life is the oxygen it produces. Without photosynthesis there would be little to no oxygen on the planet.
Explanation:
In a particular context, “epoch” can refer to a particular point of time characterized by a particular event/series of events.
While “era” refers to a period of time characterized by events in a chronological order.
Thus, an “era” can encompass more than one “epoch”.
“Period” can refer to a short interval of time or a very long interval of time.
For example:
<span>“My period of happiness….”“The period of Four Horsemen…”</span>
<span>“Eon” </span>refers to an indefinitely long time. <span>Eon is presumed to consist of at least 2 eras.</span>
Answer & Explanation:
All archeas are single-celled organisms, and despite having prokaryotic cells, there are both similarities and differences between archaea and bacterial cells and also with eukaryotes.
Archaea have only one cell that has no nucleus or real organelles, and its cells have membranes composed of branched lipids, which greatly alter the structure of the archaeal cell membranes. In addition, the archaea have only one DNA strand (uniqueness).
Animal cells differ from archeas because they are multicellular (organisms with several cells), each one having a nucleus, and they also have specialized organelles.
In addition, animal cells have compounds called phospholipids in their membranes, which are unbranched lipids, and therefore do not cause major changes in the structures of their cells. Finally, animal cells have double-stranded DNA (complementary duplication).
