Hydrothermal vents - ANSWER: Natural openings in the Earth's surface that emit hot
gases and minerals, with temperatures as high as 400°C and emit H2S and metal
sulfides.
Phosphate ester bond - ANSWER: A type of bond formed between a phosphate
group and an alcohol.
Amide bond - ANSWER: A bond formed between a carbonyl group and a nitrogen
atom from an amine.

Ribosomes - ANSWER: Molecular machines that synthesize proteins by translating
messenger RNA.
Prokaryotes - ANSWER: Prokaryotes are made up of two major groupings: the
eubacteria and the archaea, which are as different from each other as from the
eukaryotes.
Prokaryotes Size - ANSWER: Prokaryotes are generally much smaller than the
eukaryotic cells.
Archaea Divergence - ANSWER: Archaea diverged from prokaryotes, as illustrated in
the more accurate phylogenetic tree made up of prokarya, archaea and eukarya.
Prokaryotes Organelles - ANSWER: Prokaryotes do not have organelles.
Eukaryotes - ANSWER: They contain organelles like mitochondria, chloroplasts, the
endoplasmic reticulum, and the nucleus.
Eukaryotes Size - ANSWER: They are usually 10 to 100 microns in diameter.
Eukaryotes Structure - ANSWER: They can be either unicellular or multicellular.
Eukaryotes Classification - ANSWER: They are also called archaea.
Biochemical Evolution Theories - ANSWER: Margulis suggested that mitochondria
and chloroplasts evolved from the symbiotic relationship between primordial prokaryotic
and eukaryotic cells.
First Cells Formation - ANSWER: The first cells were probably formed when self-
replicating systems were enveloped in membranous vesicles.
Oparin and Haldane Experiment - ANSWER: Oparin and Haldane demonstrated that #$%^&^$
