question 15

Multiple Choice

Refer to the figure below. Which written description is appropriately matched to the figure?

• A) The behavior of primitive protocells toward molecules in the environment was likely determined by the lengths of the fatty acid tails in their membranes.
• B) The origin of life most likely involved a step in which membranes formed around building block molecules that could polymerize into larger molecules.
• C) The primitive protocell facilitated polymerization of larger biomolecules because its membrane allowed only small molecules to move in and out.
• D) Fatty acid molecules have a polar head and nonpolar tail, which allows them to self-assemble into bilayer membranes when placed in water.
• E) Primitive protocells were not self-reproducing at first, but likely evolved this capability over time.
