Which of the following extremophiles might researchers most likely use a model for the earliest organisms on Earth? An anaerobic archaean species.,
Why are eukaryotes more diverse than prokaryotes?
Since prokaryotes take up more space than eukaryotes, they're more diverse. ... This is because when it comes to the enzymes used for several of their most basic processes, notably the enzymes used for transcription and translation, archaea are more like eukaryotes than bacteria.
Which of the following statements correctly answers how the large amount of genetic variation observed in prokaryotes arises?
Which of the following statements correctly answers how the large amount of genetic variation observed in prokaryotes arises? They have extremely short generation times and large populations and They can exchange DNA with many types of prokaryotes by way of horizontal gene transfer.
Which portion of a typical prokaryotic flagellum is embedded in the cell wall and plasma membrane?
The basal body is the motor for the flagellum and is embedded in the plasma membrane (Figure 18). A hook region connects the basal body to the filament. Gram-positive and gram-negative bacteria have different basal body configurations due to differences in cell wall structure.
Which structure would prokaryotic species need for directed movement?
It consists of millions of bacteria. Most prokaryotes also have long, thin protein structures called flagella (singular, flagellum). They extend from the plasma membrane. Flagella help prokaryotes move.Mar 5, 2021
Which of the following traits do Archaeans and eukaryotes have in common?
Both can carry out asexual reproduction. Translation and transcription that occurs in Archaea is similar to that that occurs in Eukaryota (the one in bacteria is unique). DNA replication in Archaea is similar to that in Eukarya.Aug 21, 2016
What organisms are most numerous on Earth group of answer choices?
The prokaryotes are by far the most abundant organisms inhabiting planet Earth. They are also by far the most diverse, both metabolically and phylogenetically; they encompass the Bacteria and the Archaea, two out of the three major divisions of living organisms.Dec 15, 2021
Which class of animals is the most numerous on Earth quizlet?
Arthropods are the most numerous animals on Earth.
What is the difference between an F+ donor and an HFR donor?
What is the difference between an F+ donor and an Hfr donor? The Hfr donor has an F factor integrated into its main chromosome, but the F+ donor does not. You just studied 30 terms!
Which of the following types of pathogenic prokaryotes cause cholera?
Vibrio cholerae is the bacteria that causes cholera.
Which of the above species have a cell wall that consists partly of an outer membrane of lipopolysaccharide?
The cell envelopes of most bacteria fall into one of two major groups. Gram-negative bacteria are surrounded by a thin peptidoglycan cell wall, which itself is surrounded by an outer membrane containing lipopolysaccharide.
Which of the following extremophiles might Researchers most likely use as a model for the earliest organisms on Earth quizlet?
Which of the following extremophiles might researchers most likely use a model for the earliest organisms on Earth? An anaerobic archaean species.
