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, we analyze each option:

• Option 1: Mendel's work is on genetics, not cell theory, so this is incorrect.
• Option 2: Mendel preceded Morgan, so Morgan couldn't be continued by Mendel. Incorrect.
• Option 3: Morgan continued Mendel's genetic research (Mendel used pea plants, Morgan used fruit flies as a new experimental method). This fits.
• Option 4: Cell theory is unrelated to Mendel's genetic research. Incorrect.

Answer:

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