Unit 6 Origin of Life - DAY 2

determining how pollution is affecting life in the ocean

determining how the atmosphere became rich in oxygen

determining how cells could develop from nonliving matter

determining how organelles developed from symbiotic organisms

It helps us understand the diversity of living organisms

It provides insight into the basic elements that make up life

It allows us to explore scientific explanations and evidence

All of the above

Oparin-Haldane hypothesis involves chemical evolution.

Endosymbiosis hypothesis explains the origin of eukaryotic cells.

Chemical evolution lasted longer than biological evolution.

Multicellular organisms formed before single-cell eukaryotes.

protists

bacteria

amino acids

RNA strands

Organic molecules are present today in extremely high concentrations

The process of synthesizing organic molecules from a mixture of gases has been successfully modeled in the laboratory

Amino acids spontaneously form from molecules in the atmosphere today

No other alternative hypotheses have been introduced

onset of photosynthesis

origin of genetic material

synthesis of organic molecules

formation of the plasma membrane
