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 which situation would new technology be most likely to cause a change in an existing theory about new structures a cell?

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?
Our current understanding of evolution is called a theory because it has been
