Answer:
The correct answer is B. prokaryotes
Explanation:
Archaea and bacteria are the organisms that come under prokaryotes. In Prokaryotes, pro indicate before and karyote indicate nucleus. So these organisms do not have a true membrane-bound nucleus in which they can store their genetic material.
As archaea and bacteria do not have membrane-bound nucleus their genetic material freely moves inside the cytoplasm in their cell. All the prokaryotes are unicellular organisms.
The organisms that have a well membrane-bound organelle like nucleus are called eukaryotes. The genetic material of these organisms are packed in their nucleus. They can be unicellular or multicellular.
Therefore the correct answer is B. prokaryotes.
The second stage of photosynthesis is the production of glucose from carbon dioxide. This process occurs in a continuous cycle, named after its discover, Melvin Calvin. The Calvin cycle uses CO2 and the energy temporarily stored in ATP and NADPH to make the sugar glucose.
The presence of inorganic molecules is the meteorite condition in space similar to what was likely present in Earth's early atmosphere.
The earth initial atmosphere in its early form was too reducing and it was made up entirely of gases such as carbon monoxide, ammonia, methane, nitrogen and other gases.
This atmosphere did not have free oxygen, since it was the result of the mixture of metals, hydrogen and other chemical elements.
The high temperatures, ultraviolet rays and electrical discharges in the early atmosphere would have caused chemical reactions of the elements to form primitive organic molecules.
Meteorites are fragments of solid matter that contain a record of the chemical substances that existed in the early Solar System.
The most predominant gases still found in the space are hydrogen and helium.
Therefore, we can conclude that hydrogen and the presence of inorganic molecules are the initial elements that make up the Earth's early atmosphere and that they are conditions that are present in the space and so in the formation of meteorites.

Answer:
freeze and sink over and over until the entire lake was frozen.
Explanation:
This would eliminate many aquatic organisms and produce a system with far fewer life forms in lakes which freeze periodically.
