Document Summary
What is true about homoplastic structures? a. b. c. d. They evolved from two different but related species. If phosphate is added, then atp is formed. Anaerobe- survive in absence of o2 since o2 not used as electron acceptor. Autotroph- makes organic out of inorganic material in environment. Heterotroph eats previously formed organic and inorganic material. Abiotic production of nucleotides and amino acids prior to appearance of cells. Nucleotides and amino acids polymerize to form dna rna and proteins. Formation of protobionts (microspheres) polymers became enclosed in membranes. Membrane enclosed polymers evolved cellular properties self-replication leading to inheritance. 0 microspheres 0 organic polymers or molecules that forms a sphere in water. 1. protobionts (spontaneously formed based on molecules in environment) nonliving structures that evolved into cells (non living situation into living situation) Respond to osmotic and chemical changes in environment. Not self replicating as we know cells do.
