II. Protozoans, sponges, and fungi came to being.

III. Anaerobic cells appeared as the first prokaryotic cells.

IV. Multicellular organisms have evolved from unicellular eukaryotes.

What important molecule was produced by Miller and Urey when they tested the hypothesis of Oparin and Haldane by experiment?

• Amino Acids

• Methane

• Carbon dioxide

• Protein

Which pair of theories or hypotheses were both proposed by Alexander Oparin?

• Cosmozoic Theory and Coacervate Theory

• Panspermia Theory and Special Creation Theory

• Coacervate Theory and Oparin- Haldane Hypothesis

• Abiogenesis Theory and Spontaneous Generation Theory

Among the theories and hypotheses about the origin of life on Earth, Special Creation Theory is most different because:

• It has undergone a series of experimentation to prove that it is true

• It uses different observations and scientific techniques

• It is supported by evidence

• It is purely based on religious belief

Which of the following molecules is not abundant during the early formation of our planet?

• Methane

• Hydrogen gas

• Oxygen gas

• Ammonia

Why do you think the emergence of plants and animals came later than simple living organisms?

• They are too big and take time to form.

• Their cell structures are more complex.

• They are the least important factor in the environment.

• They contain more nuclei compared to lower forms of organisms

This apparatus in one of the theories of life on Earth was used to mimic what?

• Proteins

• Present Earth conditions

• Early Earth conditions

• Nucleic acids (DNA/RNA)

Lightning and solar radiation provided enough energy to transform atmospheric chemicals into biomolecules, which then accumulated in the massive ocean covering the earth’s surface. What theory is this?

• primordial soup theory

• meteorite theory

• bubble theory

• spontaneous generation

What is the most acceptable theory for the origin of life on Earth?

• divine creation

• extraterrestrial origin

• panspermia

• origin from nonliving matter

What did the Miller Urey experiment prove?

• Provided the first evidence that inorganic molecules like DNA or RNA needed for life could be formed from organic components like oxygen or hydrogen

• Provided the first evidence that organic molecules like oxygen or hydrogen needed for life could be formed from inorganic components like DNA or RNA

• Provided the first evidence that light was needed for life to be formed

• Provided the first evidence that dust is needed for life to be formed
