Question

7, 18, & 19 study questions classify each of the following events into the correct bin to describe the four stages of the origin of life. inorganic compounds evolve into organic monomers nucleotides and amino acids make their appearance organic polymers evolve dna, rna, and proteins make their appearance probionts evolve the ability to self - replicate protocells make their appearance organic polymers become enclosed within a membrane stage 1 stage 2 stage 3 stage 4

Explanation:

To solve this, we recall the four stages of the origin of life:

Stage 1: Abiotic synthesis of organic monomers

• Event: Inorganic compounds evolve into organic monomers
• Rationale: Stage 1 focuses on forming simple organic building blocks (monomers) from non - living (inorganic) substances.

Stage 2: Abiotic synthesis of organic polymers

• Events: Nucleotides and amino acids make their appearance; Organic polymers evolve
• Rationale: After monomers (like nucleotides, amino acids) are formed, they link to form polymers (long - chain molecules).

Stage 3: Formation of protocells (protobionts)

• Events: Organic polymers become enclosed within a membrane; Protocells make their appearance
• Rationale: For a cell - like structure to form, polymers need to be enclosed in a membrane, leading to the first protocells.

Stage 4: Evolution of self - replicating molecules

• Events: DNA, RNA, and proteins make their appearance; Probionts evolve the ability to self - replicate
• Rationale: The final stage involves the development of molecules (DNA, RNA, proteins) that allow for self - replication, a key characteristic of life.

Final Classification:

• Stage 1: Inorganic compounds evolve into organic monomers
• Stage 2: Nucleotides and amino acids make their appearance; Organic polymers evolve
• Stage 3: Organic polymers become enclosed within a membrane; Protocells make their appearance
• Stage 4: DNA, RNA, and proteins make their appearance; Probionts evolve the ability to self - replicate
