Multiple Choice

Which of the following is the collection of life's remains found in sedimentary rock?

• natural selection

• homologous structures

• Charles Darwin

• the fossil record

Multiple Choice

Which layer is the youngest

• 1
• 2
• 3
• 4

Multiple Choice

How do fossils provide evidence that evolution has happened on Earth?

• Fossils show how the sizes of certain animals has changed drastically over millions of years
• Fossils show that some species have gone extinct
• Fossils show how life forms present today are different than those from the past
• Different sedimentary rock layers provide evidence for how the environment has changed over time

Multiple Choice

Similarities in bone arrangements, like those in the picture, support the hypothesis that...

• these organisms are not well adapted

• these organisms share a common ancestor

• these organisms all share the same DNA sequences

• these organisms are members of the same species

Multiple Choice

Which of the following is an example of a vestigial structure?

• the wings of a red-tailed hawk
• the hind limbs of a house cat
• the fins of sharks
• the tailbone of a human

Multiple Choice

The picture shows a/an ___________

• homologous structure

• vestigial structure

Standard

Chemical Evolution

​

Organic Evolution--Endosymbiotic Theory

​

Multiple Choice

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).

1. The first Prokaryotes would have likely been chemoautotrophs and heterotrophic Anaerobes.

Edosymbiotic Theory

​2. Aerobic heterotroph develops--engulfed by another bacteria and evolves into mitochondria

3. Photosynethic Autotroph develops--engulfed by larger cell---evolves into chloroplast

Multiple Choice

Which process is an example of organic evolution?

• The Earth goes through chemical differentiation in which heavier elements sink to the core.

• Cells develop the ability to produce their own food through the process of photosynthesis.

• Lightning converts the early atmosphere into an atmosphere rich in the chemical building blocks of life.

• Large macromolecules such as polypeptides and polynucleotides are formed from smaller building blocks.

Multiple Choice

What type of organism likely evolved before aerobic organisms could have come into existence?

• fungi

• eukaryotes

• Anaerobic prokayrotes

• photoautotrophs

Multiple Choice

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.

Multiple Choice

Which statement represents the best understanding of evolutionary theory?

• Mitochondria must have evolved as endosymbionts before chloroplasts because all eukaryotes possess mitochondria, but not all eukaryotes necessarily possess chloroplasts.

• Chloroplasts must have evolved as endosymbionts before mitochondria because all eukaryotes possess chloroplasts, but not all eukaryotes necessarily possess mitochondria.

Multiple Choice

How did the first heterotrophs obtain nutrients for carrying out their life functions in the primitive atmosphere of Earth?

• They obtained their food by feeding on each other

• They absorbed nutrients directly from the environment.

Multiple Choice

Two different species contain a nucleotide sequence that is almost identical. What does this evidence suggest?

• The two species have the same number of chromosomes.

• The two species may have a common ancestor.

Multiple Choice

The endosymbiotic theory of eukaryote evolution states that organelles in eukaryotic cells are derived from bacteria. Which statement is the strongest evidence in support of the endosymbiotic theory of eukaryote evolution?

• Eukaryote organelles contain DNA similar to bacterial DNA

• Eukaryote organelles stop functioning outside of a plant cell.
