Question
Chapter 25.2, Problem 2R
Summary Introduction
To review:
The characteristic features and examples of prokaryotes that justify them as primitive organisms.
Introduction:
During the evolutionary times, organisms had undergone various phylogenetic changes. All the living beings that we come across today are believed to be the descendants of a common ancestor of life. Environmental conditions had its great impact on the evolution of different species, which have a few similarities but are relatively different.

Here is the question: What was the likely source of the raw material incorporated into the first life forms? I believe it is carbon, but I don't know why it is carbon. What I mean is, why is carbon considered the thing that makes something alive? Why are eukaryotes and prokaryotes simply considered alive just because they have carbon. Would that mean that carbon is alive because carbon has carbon? I would appreciate an anwser because I'm really trying to understand everything I run across. I love educating myself and I'm on a quest for knowledge. Thanks guys!
The TATA-binding protein (TBP) is thought to be necessary for transcription in all eukaryotic cell nuclei. Studies show that archaea, but not bacteria,have a protein structurally and functionally similar to TBP. What does this similarity suggest regarding the evolution of archaea, bacteria, and eukaryotes? How might knowledge of this similarity affect how systematists classify these organisms?
According to the endosymbiotic theory, which of
the following is NOT true about the
evolution of life on earth?
Eukaryotes and prokaryotes appeared at
about the same time and evolved
independently from each other.
O None of the other four answers (all are true
statements)
Eukaryotes evolved from symbiotic
prokaryotes living inside other prokaryotes
Mitochondria and chloroplasts are in some
ways similar to prokaryotes
The first life on earth was simple organisms,
similar to today's prokaryotes

Below is a model of the theorized changes during the origin of eukaryotic cells. Prokaryotes are not capable of phagocytosis, or engulfing outside particles by creating a pocket in the cell membrane. Which of the following changes in early prokaryotes could be predicted to result in the emergence of eukaryotic organisms? A - the development of genetic transfer mechanisms in prokaryotes B - the evolution of predatory or parasitic relationships in prokaryotes C - the emergence of collections of cells functioning together in prokaryotes D = the expansion of internal structures to support larger individual cells in prokaryotesarrow_forward
- Why are archaebacteria called living fossils?arrow_forwardin 1967, Lynn Margulis developed the endosymbiotic theory. As seen in the diagram below, the endosymbiotic theory describes how over thousands of years, free-living prokaryotes formed living communities inside larger ancestral prokaryotic cells. Today, we identify those early free-living prokaryotes as the mitochondria, chioroplasts, and possibly other organelles. Endesymbietic Theery How did the development of Margulis' theory aid in our understanding of how complex organisms came into existence? A. It provided an explanation as to why prokaryotic cells do not have a nucdeus. B. It provides an explanation as to why bacteria and mitochondria are similar in size. C. It provides an explanation of how life today could have originated from a single cell. D. It provides an explanation of how prokaryotic and eukaryotic cells use oxygen to work.arrow_forwardUsing the analogy of a one-hour countdown timer, when did prokaryotes originate?

- Why were Archaea originally thought to be simply unusual forms of Bacteria?

How wouldyou go about characterizing the new organism anddetermining if it actually is evolutionarily distinct fromBacteria, Archaea, and Eukarya?arrow_forwardThe universal phylogenetic tree of life shows the divergence of Bacteria, Archaea, and Eukarya. Studies of Lokiarchaeota help to elucidate these relationships, but the first universal tree of life was constructed by Carl Woese using ribosomal RNA sequences. There are advantages to using different types of nucleic acid for different types of analyses. What is a specific advantage of using small subunit ribosomal RNA (SSU rRNA) gene sequences for phylogenetic analysis compared with DNA sequences? ▸ View Available Hint(s) SSU rRNA sequences accumulate mutations more rapidly than protein-encoding DNA. SSU rRNA is frequently transferred through horizontal gene transfer, whereas DNA sequences are not. Primers are required in DNA sequence analysis, but not for SSU rRNA sequence analysis. Although PCR products can be visualized with SSU rRNA, this is not the case with other forms of nucleic acids. DNA sequences are too highly conserved to work well for sequence analysis; individual species are…arrow_forward
