Answers
Answer:
A) the origin of eukaryotes
Explanation:
The Endosymbiotic theory talks about how the ancestors of modern eukaryotic cells were once 2+ prokaryotic cells. This theory says that one prokaryotic cell basically lived inside another prokaryotic cell and these cells formed a long term relationship. The prokaryotic cell eventually became a permanent part of the host and eventually evolved into modern day eukaryotic cells.
The Endosymbiotic Theory explains the origin of eukaryotes.
What is endosymbiotic theory?The endosymbiotic theory posits that some eukaryotic cell organelles, such as mitochondria and plastids, evolved from free-living prokaryotes.
The most significant examples of endosymbiosis are represented by the endosymbiotic acquisition of plastids and mitochondria, introducing photosynthesis and respiration to eukaryotes.
Eukaryotic cells may have evolved when multiple cells joined together into one. They began to live in what we call symbiotic relationships. The theory that explains how this could have happened is called endosymbiotic theory.

A). by repeating the experiment several times B). by charging the experimental procedure C). by asking other scientists what they think about the results D). by modifying the results so they are close to the expected results
Answers
Answer:
The answer is A by repeating the experiment several times
Explanation:
i did it on edu
By repeating an experiment many times, scientists increase confidence in the results. So, the correct option is (A).
What is an experiment?An experiment is defined as a procedure which is carried out to support or disprove a hypothesis. It determines the efficacy or potential of something previously unusable. It provides insight into cause and effect by demonstrating what results when a particular factor is manipulated.
An experiment is defined as a type of empirical study that involves manipulation of an independent variable, measurement of a dependent variable, and control of extraneous variables. This extraneous variable is any variable other than the independent and dependent variables.
The best approach when conducting a scientific experiment is to test repeatedly and make sure the experiment can be repeated.
Thus, by repeating an experiment many times, scientists increase confidence in the results. So, the correct option is (A).
