History of Life on Earth

One that contains oxygen

One that has hydrogen bonds

One that has covalent bonds

One that contains carbon

The experiment demonstrated the need for excessive energy in order to create new molecules.

The experiment showed that life on earth must have formed from space or hydrothermal vents.

The experiment showed organic molecules forming and organic molecules make up all life on Earth.

The experiment provided evidence for Darwin's theory of evolution.

contains genetic material

forms a cell

maintains homeostasis

RNA is not as stable because it is single stranded.

RNA is not as versatile because it does not contain uracil.

RNA is reserved for more simple organisms with simpler proteins.

RNA is able to escape the nucleus so DNA needed to be made to stay in the nucleus.

The Oxygen Revolution allowed for the development of photosynthesis, which increased the amount of carbon dioxide in the atmosphere.

Due to an increase in atmospheric oxygen, aerobic organisms flourished, causing an explosion of cellular respirating organisms.

Due to more organisms using oxygen, photosynthesis became an outdated mode of providing organisms with energy.

The Oxygen Revolution allowed for the development of more efficient energy sources, such as fossil fuels.

Prokaryotes worked cooperatively to create a multicellular eukaryote.

Eukaryotes were formed when prokaryotes underwent endosymbiosis.

Eukaryotes evolved separately in a phylogenic tree than prokaryotes.

Prokaryotes evolved from eliminating useless organelles in eukaryotes.
