Question

the concept that genes establish the boundaries within which we may operate is known as: a range of interaction b genetic - environmental correlation c diathesis - stress model d epigenetics. which technique for studying the brain measures brain structures using a magnetic field that excites the atoms in the body? a cat b mri c pet d eeg

Explanation:

1. For the first question about the brain - imaging technique using a magnetic field to excite atoms in the body, MRI (Magnetic Resonance Imaging) works on this principle. CAT (Computerized Axial Tomography) uses X - rays, PET (Positron Emission Tomography) uses radioactive tracers, and EEG (Electroencephalogram) measures electrical activity of the brain.
2. For the second question, the concept that genes establish the boundaries within which we may operate is the range of reaction. Genetic - environmental correlation refers to the association between genetic and environmental factors. The diathesis - stress model is about the interaction between a pre - existing vulnerability (diathesis) and stress to cause a disorder. Epigenetics is the study of changes in gene expression without changing the DNA sequence.

Answer:

1. B. MRI
2. A. range of interaction
