Are outcomes of binomial experiment dependent on each other?
No, the outcomes of a binomial experiment are considered independent if the probability of success remains the same for each trial and the trials are performed under the same conditions. Each trial's outcome does not influence the outcome of subsequent trials.
An experiment is performed with peppered moths. The table below shows the populations before and after the trees turned black. Based on this data which is a reasonable hypothesis for what happened aft?
The peppered moths with light-colored wings decreased in population after the trees turned black, while the peppered moths with dark-colored wings increased in population. A reasonable hypothesis is that the moths with dark-colored wings had a survival advantage in the new environment as they were better camouflaged against the black trees, while the light-colored moths became more visible to predators.
What was a historical experiment performed to test the theory of spontaneous generation?
In 1668, Italian physician Francesco Redi performed an experiment to test the prevailing theory that maggots were formed spontaneously (abiogenesis) in rotting meat. He took 4 pieces of fresh meat and put them in containers, covering two of the containers with paper and leaving the other two uncovered. In a day or two, maggots appeared in the meat samples that were uncovered, because flies had laid their microscopic eggs in the meat. No maggots appeared on the covered pieces of meat, the ones the flies could not reach. In 1745, however, John Needham experimented with boiling solutions to prevent spoilage in grain. Needham either did not boil his solutions long enough, or accidentally contaminated the results, because he found bacteria that had apparently appeared spontaneously. These results were challenged by the Italian Lazzaro Spallanzani in 1768, and eventually by Louis Pasteur, who proved in 1859 that bacteria existed in the open air but did not form by themselves.
Which scientist performed an experiment that claimed to support spontaneous generation?
> Louis Pasteur (1626-1697) discovered spontaneous generation. Actually, Louis Pasteur (1822-1895) is credited with DISPROVING spontaneous generation, expanding the work of other scientists before him. Aristotle synthesized the theory of spontaneous generation, compiling and expanding on the work of earlier natural philosophers.
An in vivo experiment involves making observations in a?
living organism or system, typically performed within its natural biological context. This approach enables researchers to study the effects of various treatments, interventions, or conditions on the organism as a whole, providing valuable insights into biological processes, disease mechanisms, and treatment strategies.
Which scientists performed the cathode Ray experiment leading to the discovery of electrons?
Dalton performed the cathode ray experiment.
What is Needham's experiment?
in 1745 an english needham's performed an experiment to support abiogenesis
Which scientist performed the cathode ray experiment leading to the discovery of electrons?
Dalton performed the cathode ray experiment.
What variable is unknown until the experiment is performed?
The independent variable is the variable that is unknown until the experiment is performed. This is the variable that is manipulated by the researcher to observe its effect on the dependent variable.
What is the possible result when an experiment performed in math?
A fat turtle
Which variable is unknown until the experiment is performed?
A responding variable
Why is it important for scientist state a conclusion?
To clearly state why the experiment was performed
Is it correct to say 'You performed the experiment'?
Yes, that is a grammatically correct sentence.
What is a test or trial that is performed in order to discover something?
An experiment is a test or trial that is performed in order to discover something. It involves making observations, measurements, and collecting data to test a hypothesis or answer a specific question.
Two scientists have performed the same experiment and have gotten different results why?
They have gotten different results because they performed it from their knowledge.
Paul performed an experiment He recorded the changes water goes through as it is frozen and boiled. His experiment is most likely based on the?
volume of liquids
What actually occurs in a probability experiment?
In a probability experiment, various outcomes are possible and the experiment is conducted to observe which outcomes occur. The experiment is performed repeatedly to collect data and determine the likelihood or probability of each outcome happening. The results of the experiment are analyzed to understand and make predictions about future occurrences of the event.
