Which of these questions is not scientifically testable and why?
In order to unravel the mysteries of human genetics scientists have studied the genetics of many other
organisms. One organism that has taught us a lot is the fruit fly. Fruit flies (Drosophila melanogaster)
reproduce sexually. Sex cells from both parents, each containing four chromosomes are combined to
create a single-celled zygote with eight chromosomes. That cell undergoes mitotic cell division to create
identical copies of itself. These cells differentiate into specialized cells. Knowing that the cells in the eyes
have the same DNA as the cells that make up the body of the fruit fly, questions were asked to clarify the
role of DNA and chromosomes in coding the instructions for traits passed from parents to
offspring.
2. Which of these questions is NOT scientifically testable?
O Do eye cells and the cells that make up the body make the same proteins?
Does all DNA in a cell code for protein?
What makes eye cells different from the cells that make up the body?
O Should scientists study fruit flies to determine how DNA codes for traits?

Expert Solution
Step 1

"Scientifically testable" means that a hypothesis or question can be tested through empirical observation or experimentation, using the scientific method. In other words, it can be investigated through objective and measurable means, and its results can be replicated and verified by others. A scientifically testable question or hypothesis is specific, well-defined, and can be supported or refuted through evidence-based observations or experiments. It is a fundamental principle of scientific research that allows scientists to evaluate and refine their understanding of the natural world based on evidence.
