Chapter 15, Problem 4WIO
Summary Introduction
To enlist:
A logical sequence of events that starts with an early prokaryote and ends with modern multicellular eukaryotes.
Concept introduction:
The origin of life on Earth was not possible until the advent of favorable conditions on Earth. The Earth and other planets formed around 4.6 billion years ago. The Earth was a red hot ball at that time and it cooled down to form crust around

- Serial endosymbiosis is the most supported theory on how the first eukaryotic cells evolved from prokaryotic cells. The figure depicts the evolution of eukaryotic cells which include links to prokaryotic cells from early in the history of life. Identify the cellular structures involved in the connection of eukaryotic and prokaryotic cells. Describe the characteristics of the cellular structures that supports the evolutionary connection. State a claim on how eukaryotic cells evolved. Using evolutionary evidence justify your claim. The cells modeled above are a result are descendants of an original cell.arrow_forwardEvolutionary microbiologists developed a theory about a common ancestor for all eukaryotic cells. 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_forwardAccording 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 prokaryotesarrow_forward

This organism is prokaryotic and does not eat. It is made up of only one cell. What domain/kingdom is it probably in?

Eukaryotes and archaea are most closely related to each other than either are to bacteria. MRNA rRNA TRNA 0000arrow_forward
- After the glacial retreat at the end of the last ice age, some three-spine stickleback fish (Gasterosteus aculeatus) were isolated in small lakes. A mutation occurred in these fish that resulted in the loss of pelvic spines. Today, all freshwater sticklebacks lack pelvic spines, but are still classified as members of the same species as marine sticklebacks. Scientists collected sticklebacks from both marine and freshwater environments and placed them together in a controlled environment. Which of the following statements describes the effect of the mutation on their ability to interbreed? They should be able to interbreed and produce fertile offspring. They will not be able to interbreed and produce offspring because of hybrid breakdown. They will not be able to interbreed and produce offspring because of mechanical isolation. They should be able to interbreed and produce offspring, but the offspring may experience reduced hybrid fertility.arrow_forwardMitochondria and chloroplasts contain some DNA, which more closely resembles prokaryotic DNA than (eukaryotic) nuclear DNA. Use this information to suggest how eukaryotes may have originated.arrow_forwardDescribe the evidence that supports the endosymbiotic theory of evolution of eukaryotes.arrow_forward
