Pro vs Eu & Biomolecules

A fossilized cell is discovered, and evidence suggests it reproduced on its own and had DNA, but a membrane did not enclose its DNA. Which type of organism would this most likely be?

• prokaryote

• eukaryote

• plant cell

• animal cell

Answer explanation

The fossilized cell with DNA but no enclosed membrane is characteristic of prokaryotes, which lack a nucleus and membrane-bound organelles.

________ are small individual molecules that when linked together form a _______

• polymers

  monomer

• carbohydrates

  lipid

• proteins

  nucleic acid

• monomers

  polymer

Answer explanation

Monomers are small individual molecules that when linked together form a polymer, making the correct answer choice 'monomers' and 'polymer'.
