They are all located in the dermis.
Answer:
The independient variable in this study is the memory-enhancing drug that Dr. Bonne DeMuth is testing on the students.
Explanation:
In research studies, there are independent variables which are those that are being studied and analyzed. When these variables are intervened, these will be the ones that will directly affect the results.
So , in this case Dr Bonne DeMuth is trying to find out if a memory-enhancing drug would help decrease the time it takes students to learn how to trace a maze.The independent variable in this case would be the drug analyzed by Dr Bonne DeMuth and the intervention that is being carried out on this variable is to know if it can achieve the desired effect(decrease the time it takes students to learn how to trace a maze).
Answer:
Functional MRI.
Explanation:
Functional MRI (magnetic resonance imaging) may be defined as a technique used to measure the activity of brain with the blood flow. This technique works on the principle that neuronal activation and blood flow are coupled with each other.
The brain part become active when people starts lying and their blood flow increases. The functional MRI technique is used to detect the brain area that increases when participants told lie because this technique depens on blood oxygen level.
Thus, the answer is functional MRI.
