(i think this question wasn’t really a question but i answered it anyway lol. i’m sorry that chemistry is hard. good luck!)
Correct answer: Hippocampal
Brain imaging, structural or functional helps us to study the structure and functions of the brain and other parts of the nervous system. Post Traumatic Stress Disorder affects a network of brain areas, like hippocampus, amygdala, cingulate, and prefrontal cortex. In PTSD, the concentrations of corticotropin- releasing factors increases in the cerebrospinal fluids. This stress also leads to the change in the volume and functions of hippocampus, which has a crucial role in memory.
Answer:
An identical setup but replacing the enzyme with an equal volume of water
Explanation:
When carrying out any experiment, it is important to set out a control in order to increase the reliability of the data and results.
The control minimizes the effects of variables other than the independent variable.
In the above experiment, starch has to be eliminated and replaced with water. Water does not have starch hence the digestive enzyme being tested will not have any effects making the data and results from the experimental group reliable.
