1) what would be a hypothesis for morgans experiment?

2) what is the independent variable in the experiment?

3) what is the dependent variable in the experiment?

4) what is missing from the design of the experiment?

5) why is it hard to improve the hypothesis (explain)

6) what would you do to improve the experiment?

7) can a theory be derived from this experiment? why or why not

Awoman whose sister tested positive for a specific mutation in the brca1 gene, which increases the risk for breast and ovarian cancer, is found not to have that mutation but does have a mutation of unknown significance near the known mutation site. how should this woman be counseled? select one: a. she should be informed that her risk for breast cancer is greater than the general population but not as great as her sister’s risk. b. she should be informed that because she does not have the mutation, her risk for breast cancer is not greater than that of the general population. c. she should be informed of her gene mutation status and be presented with all the available prophylaxis options and reconstruction options. d. she should be informed that she does not have the specific mutation but that because another mutation is present she should be vigilant about screening
