The endosymbiotic hypothesis postulates that an early eukaryotic cells lacking mitochondria and chloroplasts phagocytosed early aerobic prokaryotes and photosynthetic prokaryotes and rather than
What else can I help you with?
Why is the endosymbiotic theory not proved yet?
The endosymbiotic theory is widely accepted as a strong scientific hypothesis; however, definitive proof is challenging due to the lack of direct observational evidence from billions of years ago when the theorized events occurred. While there is substantial supporting evidence, such as the similarities between organelles like mitochondria and chloroplasts with free-living bacteria, the theory cannot be definitively proven beyond any doubt.
A hypothesis that is supported by evidence gathered in the research process is called a what?
Apex: conclusion
A scientist on television states that a hypothesis cannot be proven Access why this statement is correct?
This statement is correct because a hypothesis is a proposed explanation that has not been validated through experimentation and evidence. Scientific inquiry aims to test and gather evidence to support or reject a hypothesis, rather than proving it true. It is always possible for new evidence or data to emerge that could challenge or refine a hypothesis.
The results you expect when you test hypothesis?
You are supposed to assume/expect that nothing happens, or the norm happens. E.g. if you are testing if plants grow more in light, you assume they dont, then see if that expectation is consistent with the result.
What evidence supports his hypothesis?
The hypothesis is supported by data from previous research studies, observational data, and controlled experiments. This data may include statistical analyses, graphs, tables, findings from literature reviews, and expert opinions. Additionally, the hypothesis may be supported by correlations, significant p-values, and reproducible results from multiple studies.
What did chloroplast evolve from according to the endosymbiotic hypothesis?
They arose from a symbiotic union of two organisms.

What did chloroplasts eveolve from according to the endosymbiotic hypothesis?
They are thought to be evolved from photosynthetic bacteria. They have circular DNA and 70s ribosomes as bacteria
What are the comparative strengths and weaknesses of the endosymbiotic and the autogenic hypotheses?
The endosymbiotic hypothesis posits that eukaryotic cells originated through symbiotic relationships between different species of prokaryotes, which explains the presence of mitochondria and chloroplasts with their own DNA. Its strength lies in the genetic and structural similarities between these organelles and prokaryotes, providing strong evolutionary support. However, it may struggle to explain the full complexity of eukaryotic cell structures and functions. In contrast, the autogenic hypothesis suggests that eukaryotic cells evolved from prokaryotic ancestors through internal compartmentalization, emphasizing the role of cellular mechanisms. While it accounts for cellular complexity, it lacks the compelling evolutionary evidence seen in the endosymbiotic model.
How evidence test the hypothesis?
Evidence tests a hypothesis by providing data that either supports or refutes it. This process involves collecting observations or experimental results that are relevant to the hypothesis. If the evidence consistently aligns with the predictions made by the hypothesis, it strengthens its validity; if the evidence contradicts the hypothesis, it may lead to its rejection or revision. Ultimately, rigorous testing and evaluation of evidence are essential for establishing scientific credibility.
What evidence would you expect if your hypothesis was true?
The evidence that made you come to that conclusion. Remember that a hypothesis is an educated guess
Should hypothesis be supported by evidence?
Yes, hypotheses should be supported by evidence to be considered valid. Evidence helps to confirm or refute the hypothesis, guiding further research and understanding of the subject. In scientific inquiry, robust evidence strengthens the credibility of the hypothesis and contributes to the development of knowledge. Ultimately, without evidence, a hypothesis remains speculative and unsubstantiated.
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.
How does a hypothesis become a scientific hypothesis?
when there s proof to back it up with evidence or an experiment to test the hypothesis
What is a scientific definition for evidence?

When the evidence in a scientific experiment does not support the hypothesis what should the scientist do?
When the evidence in a scientific experiment does not support the hypothesis the scientist:Confirm through repeated experimentation that the evidence is validReject the hypothesisDevelop another hypothesis that is consistent with the valid evidence
