Prompt In the modern age, the use of holistic and supplemental substances has become a huge economic market. As guided by
the FDA, companies must label their supplements accordingly and include a message that you should consult with a
medical professional before starting a course of chemical supplementation. With that said, supplements are available OTC
(over-the-counter) with limited control, and anyone can purchase them and use them without a prescription or medical
guidance
One such type is creatine-based supplements. Creatine phosphate is a common chemical that is taken by athletes to boost
their stamina and general performance. The chemistry behind its use makes phosphate more available to mitochondria to
increase the production of ATP for cells to use to do work. These are all chemicals that occur naturally in our bodies but in
this form are taken to boost the normal levels. Many scientists and researchers discourage their use citing possible
negative effects. Yet, athletes will counter with the benefits of using them.
Do you think performance-boosting supplements should be banned or better regulated or do we leave the choices entirely
up to the public? Give concrete reasoning behind your opinion.

To answer this question, researchers studied populations of the dusky salamander (desmognathus ochrophaeus) living on different mountain ranges in the southern appalachian mountains. the researchers tested the reproductive isolation of pairs of salamander populations by leaving one male and one female together and later checking the females for the presence of sperm. four mating combinations were tested for each pair of populations (a and b)—two within the same population (female a with male a and female b with male b) and two between populations (female a with male b and female b with male a). the proportion of successful matings for each mating combination was measured. for example, when all the matings of a particular combination were successful, the researchers gave it a value of 1; when none of the matings were successful, they gave it a value of 0. then the researchers calculated an index of reproductive isolation that ranged from 0 (no isolation) to 2 (full isolation). the reproductive isolation value for two populations is the sum of the proportion of successful matings of each type within populations (aa + bb) minus the sum of the proportion of successful matings of each type between populations (ab + ba). the table provides data for the geographic distances and reproductive isolation values for 27 pairs of dusky salamander populations.
