Answer:
E. It takes a picture of the brain according to oxygen levels. More oxygen in an area indicates more activity in that area.
Explanation:
Haemoglobin is diamagnetic when oxygenated but paramagnetic when deoxygenated. This distinction in magnetic characteristics leads to tiny variations in the blood MR signal. Since blood oxygenation differs, these variations can be used to identify brain activity depending on the concentrations of neural activity.
<em>Hypotonic solutions contain a low concentration of solute relative to another solution ( The cells cytoplsm) </em>
<u>Thus, when a cell in placed in a hypotonic solution, the water diffuses into the cell, which causes the cell to swell up. </u>
<em>The cell has lower solute concentration than the solution. So the solution is HYPERTONIC and the cell is HYPOTONIC. </em>
As a result, a cell that does not have a rigid cell wall, such as a red blood cell, t'will most definitely swell and burst when placed in a hypotonic solution.
