An is a principle that has been scientifically verified?
An axiom is a statement that is accepted as true without needing proof. It serves as a basic assumption in a system of logic or mathematics and is used to derive other statements.
True or false Darwin's theory of evloution did not affect the way in witch specie were classified?
False. Darwin's theory of evolution greatly influenced the way species were classified. It led to the development of phylogenetic classification based on common ancestry, replacing the earlier morphological classification system. This new approach considers evolutionary relationships when grouping species together.
How did the study of Galapagos finches help Darwin to form some of his theories and how do we know that some of these theories are true?
The subtle differences between the beaks of Galapagos finches, and their distribution over the different islands helped Darwin to formulate his theory of Natural Selection. We know that this is true because it is constantly observable in the world around us.
How does Alfred Russell Wallace's theory compare to Darwin's theory of evolution?
its the same
What theory does the fossil record support?
It is generally thought to support the Theory of Evolution.
What is the theory that says prokaryotic parasites once lived in eukaryotic cells?
This is the endosymbiotic theory.
What is the endosymbiotic theory?
The Endosymbiotic Theory is a theory about how mitochondria and chloroplasts formed. The theory suggests that both the mitochondria and chloroplasts were once prokaryotic cells that were ingested but not digested by eukaryotic cells. This would explain why both have their own DNA.
The endosymbiotic theory was supported by the scientist?
Lynn Margulis was the scientist who proposed and championed the endosymbiotic theory. She provided evidence to support the idea that eukaryotic cells evolved from symbiotic relationships between different prokaryotic organisms.
Theory of endosymbiosis?
The endosymbiotic theory explains the origin of chloropasts and mitochondia. Symbiosis is the mutual benefit of two organisms living together. This was the basis of the theory.
When was the endosymbiotic theory proposed?
The endosymbiotic theory was proposed in the 1960s by Lynn Margulis to explain the origin of eukaryotic cells. It suggests that eukaryotic cells evolved through a mutually beneficial relationship between primitive prokaryotic cells.
What theory was developed around the idea that some eukaryotic organelles evolved from proyarotic organisms?
The endosymbiotic theory proposes that eukaryotic organelles, such as mitochondria and chloroplasts, originated from engulfed prokaryotic cells that developed a symbiotic relationship within the host cell. This theory suggests that these organelles were once free-living bacteria that were engulfed by early eukaryotic cells and eventually evolved into essential components of eukaryotic cells.
Which of the following would not support the endosymbiotic theory of the origin of mitochondri and chloroplasts?
Both contain DNA
What organisms created the modern mitochondria?
Aerobic bacteria evolved into mitochondria.It is explained in endosymbiotic theory.
What theory states that mitochondria and chloroplasts are derived from free-living prokaryotic cells?
The endosymbiotic theory proposes that mitochondria and chloroplasts were once free-living prokaryotic cells that were engulfed by a primitive eukaryotic cell through symbiosis. Over time, these engulfed cells evolved into organelles within the host cell, leading to the development of modern eukaryotic cells.
What statement fails to support the endosymbiotic theory?
A statement that fails to support the endosymbiotic theory would be one that asserts that all eukaryotic organelles were independently formed within the cells, without any symbiotic relationship with prokaryotic cells. This contradicts the evidence and principles of the endosymbiotic theory, which suggests that organelles like mitochondria and chloroplasts originated from ancient symbiotic relationships between prokaryotic cells and ancestral eukaryotic cells.
Endosymbiotic theory explains the formation of organelles surrounded by how many membranes?
Endosymbiotic theory explains the formation of organelles surrounded by two membranes. This theory suggests that eukaryotic organelles such as mitochondria and chloroplasts originated from symbiotic prokaryotic cells that were engulfed by a host cell, leading to a mutually beneficial relationship.
What are the 3 main steps of the endosymbiotic theory?
The endosymbiotic theory was first articulated by Russian botanist Konstantin Mereschkowski in 1910. It states that several key organelles of eukaryotes began as symbioses between two or more single-celled organisms.
