Hello everyone here We have a question that says blank are structures that are formed from the aggregation of a biotic components and provide insights on the origin of life. A rib enzymes. Rib enzymes are RNA molecules that have the ability to catalyze specific biochemical reaction. So it is not a be stromatolites. Stromatolites are microorganisms that produce adhesive compounds that submit sand and other rocky materials, so it is not be see proto sal's proto cells or structures that are formed from the aggregation of a biotic components and provide insights on the origin of life. So it is see and Lucas cells are a venerable ancestor that was a single celled bacterium like organism. So it is not D. So our answer here is c proto sales. Thank you for watching. Bye.
