Which of the following would be a warning sign that information about a weight loss medication is not reliable science? a. the investigation compared a group that took the medication to a control group that did not take the medication. b. the scientists and all test subjects involved in the investigation work for the company that sells the medication. c. the weight loss medication worked for 95 out of the 100 test subjects, while only 15 of the 100 control subjects lost weight. d. the weight loss results were replicated by scientists conducting a study at an independent institution

I think the best option is C

Hope this helps

The correct answer is B. The scientists and all test subjects involved in the investigation work for the company that sells the medication.

Explanation:

In science, a medication, product or similar is only considered as reliable if it has been tested following the scientific method and if there are not interests that can affect the process or the result. This commonly implies, using the medication in a test group and compare the results to a control group that does not use medication, prove there was a positive effect on the test group people from the control group did not have and also  being able to replicate the study which means this can be applied with more groups and the results would be consistent. However, that scientist and test subjects work for the company that sells the medication is not a factor that contributes to reliability and indeed is a warning sign because due to their interest in selling the medication they can alter or influence testing to sell the medication and therefore this is not reliable.

the answer is learned

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
