although scientific theories are based on strong evidence, they can change over time. which of the following correctly explains why scientific theories change?
new theories require changes to the scientific process, so the theory changes as a result
scientists argue, re - examine, and consider new explanations to new data
theories are hypotheses that have gained support and change as the hypothesis changes
scientists are often incorrect in their initial hypotheses, so the theory changes
fruit flies are commonly used in genetic investigations that focus on traits passed from parents to offspring over several generations. what can you infer is the reason fruit flies are the most commonly used organism for this type of investigation?
fruit flies are relatively inexpensive
scientists prefer to study what has previously been studied
society does not have ethical issues with lab - kept fruit flies
many more generations can be studied using short - lived organisms

Explanation:

For the first question about scientific - theory change, new data can lead to re - examination of hypotheses and thus changes in theories. For the second question about fruit flies in genetic investigations, their short life - span allows for studying multiple generations quickly.

Answer:

Question 1: New theories require changes to the scientific process, so the theory changes as a result of re - examining and considering new explanations to new data.
Question 2: Many more generations can be studied using short - lived organisms.
