Question

which is the best example of a hypothesis leading to new experimental methods?
gregor mendel influenced the development of the theory that everything is made of cells.
gregor mendel continued the genetic research of thomas hunt morgan, but mendel used pea plants.
thomas hunt morgan continued the genetic research of gregor mendel, but morgan used fruit flies.
the theory that everything is made of cells influenced gregor mendel in his research.

Explanation:

To determine the best example of a hypothesis leading to new experimental methods, we analyze each option:

• Option 1: Mendel influencing cell theory development is not about hypothesis leading to new experimental methods in genetics.
• Option 2: Mendel using pea plants and Morgan continuing research doesn't show hypothesis leading to new methods.
• Option 3: Morgan continuing Mendel's genetic research and using fruit flies shows that Mendel's hypothesis (about genetics) led Morgan to develop new experimental methods (using fruit flies) to further explore genetics. This fits the idea of a hypothesis (from Mendel) leading to new experimental approaches.
• Option 4: Cell theory influencing Mendel's research is about cell theory's influence, not hypothesis leading to new experimental methods.

Answer:

C. Thomas Hunt Morgan continued the genetic research of Gregor Mendel, but Morgan used fruit flies.
