Evolution Quizizz

Which statement explains that chemical evolution and organic evolution are not mutually exclusive events, but rather they operate simultaneously in the evolution of life?

• The formation of new structures influences the molecular changes in organisms.

• The production of new proteins is directly proportional to increases in the complexities of the organisms.

• The changes that occur at the molecular level result in changes of the species’ phenotypes.

• The chemical reactions that occur in organisms cause their bodies to evolve and change the species.

A student creates a flow chart showing how life started and evolved on Earth, as shown.

A classmate notices an error in the flow chart. Which statement identifies the conceptual error in the flow chart?

• Aerobic organisms evolved after anaerobic organisms.

• Autotrophic organisms evolved before heterotrophic organisms.

• Organic compounds evolved after both autotrophic and heterotrophic organisms.

• Photosynthetic organisms evolved before the formation of organic compounds.

Gases most likely found in the primitive atmosphere included methane, ammonia, and hydrogen and excluded oxygen and carbon dioxide. Which organisms are most likely considered to be the first to evolve?

• multicellular plants that used the gases during photosynthesis for autotrophic nutrition

• multicellular animals that used the gases during photosynthesis for autotrophic nutrition

• aerobic prokaryotes that used the gases for heterotrophic nutrition

• anaerobic prokaryotes that used the gases for heterotrophic nutrition

What is the difference between chemical and organic evolution?

• Chemical evolution describes how complex organic molecules were first formed from simpler inorganic molecules on early Earth, while organic evolution describes the gradual process by which living organisms have undergone changes from simple unicellular creatures to complex multicellular organisms.

• Chemical evolution describes the development of inorganic compounds and polyatomic ions on early Earth, while organic evolution describes the development of complex macromolecules (like starches and nucleic acids) from simpler monomers (such as monosaccharides and nucleotides).

• Organic evolution describes how complex organic molecules were first formed from simpler inorganic molecules on early Earth, while chemical evolution describes the gradual process by which living organisms have undergone changes from simple unicellular creatures to complex multicellular organisms.

• Organic evolution describes the development of inorganic compounds and polyatomic ions on early Earth, while chemical evolution describes the development of complex macromolecules (like starches and nucleic acids) from simpler monomers (such as monosaccharides and nucleotides).

The first organisms to appear on Earth were formed from simple organic aggregates. These organisms were called heterotrophs.

Which type of energy-releasing process was most likely performed by those first heterotrophs?

• aerobic respiration

• anaerobic respiration

• photosynthesis

• protein synthesis

Which statement best describes the evolution of cells on Earth?

• Both chemical and organic evolution occurred simultaneously.

• Chemical evolution occurred first, eventually making organic evolution possible.

• Organic evolution occurred first, eventually making chemical evolution possible.

• Neither chemical nor organic evolution was able to occur until cells came into existence.

• 1: photosynthesis; 2: cellular respiration

Charles Darwin proposed the theory of evolution which stated that all species developed by inheriting useful variations of their ancestors, and gradually, new species were formed. After Darwin proposed this theory, the process of classifying species was modified to show the relationships among different species.

According to Darwin, what was the guiding factor behind the evolution of species?

• continent formation

• extinction event

• high reproduction rate

• natural selection

The European garden snails that live in fields and hedges have yellow shells with stripes, whereas those that live in wooded habitats have brown shells without stripes. Why does natural selection favor genetic variation among European garden snails occupying different habitats?

• It helps the snails avoid being seen by predators.

• It helps the snails adapt to different feeding behaviors.

• It helps the snails maintain a constant body temperature.

• It helps the snails limit themselves to a particular habitat.
