Gregor Mendel was the first scientist to use statistics to analyze scientific data. Before Mendel’s experiments, scientists believed that organisms acquired traits from their environment and passed them on to their offspring. After Mendel’s discoveries were accepted, scientists realized that traits passed to offspring were the result of genes being passed from parents to offspring. This is an example of
What do hypotheses, theories, and laws have in common?
Which is the correct order in the scientific process?
The statement “force equals mass times acceleration (F=ma)” is Newton’s second law of motion. Why is this a law rather than a theory?
The development of a new experimental method is most likely to change a theory if it makes it possible to
Gregor Mendel demonstrated that traits are passed from parents to offspring independently of one another under all circumstances that he tested. All other genetics researchers have observed this as well. Based on this information, the statement can be made that “traits are passed from parents to offspring independently of one another.” Which describes the statement of fact?
In the early days of germ theory, contagious diseases were thought to be caused only by fungi or bacteria. In the 1890s, Dmitri Ivanovski filtered extracts from diseased tobacco plants and discovered that the disease could be transmitted to new plants through the filtrate. He hypothesized that something smaller than bacteria or fungi was responsible for the transmission of the disease. Which best explains how Ivanovski’s work led to a change in the germ theory?
A testable hypothesis could be formed from which question?
How does a law differ from a theory?
How should you test a hypothesis?
