The glucocortocoids has the ability of increasing the bone
loss while having a composition of serotonin in high levels will likely have
the bone density to be at its low level. To complete the sentence;
Glucocorticoids increase bone loss; high levels of serotonin lead to low bone
density.

TOuch and pain are controlled by different regions of the brain, so I gonna treat these terms separately:
PAIN: one thing seems certain: there is no single "pain centre" whose only activity could account for all facets of pain. In other words, no lobotomy of any particular region of the brain completely removes the pain. So there are many regions that are responsible for pain: The reticular formation and the thalamus (specifically the Deep lemniscal territory) which is responsible for both touch and pain sensations
TOUCH: touch sensation are processed by parietal lobe in the brain cortex (which is also responsible for sight and hearing), and the deep lemniscal territory in the thalamus.

Answer:
C. Yes, Trisha should have a group of frogs in her experiment that is not exposed to any pesticide at all
Explanation:
The election of a control group is essential in an experiment. Its principal purpose is to allow the discrimination of the results obtained by the treatment in the study (in this case, the effect of pesticide) from the results that might be a consequence of other factors. The control group must be selected from the same population of the treatment group. All the groups must be similar in every variable that might influence the results, except for the study treatment.
- Control group: Frogs that are not exposed to any pesticide
- Treatment one: Frogs exposed to a certain concentration of pesticide
- Treatment two: Frogs exposed to an increased concentration of pesticides ...
And so, the number of treatment groups will depend on the different concentrations of pesticides Trisha wants to study.
All groups must belong to the same population and of course, to the same species. They must also be exposed to the same variables, excepting for the pesticide variable.
