Neuroscientists studying memory have benefited greatly from the use of MRI scans. They are able to see brain activation while a person is remembering. This has led them to conclude that .

Explanation:

Magnetic resonance imaging (MRI), also known as magnetic resonance tomography (MRI) or nuclear magnetic resonance imaging (MRI, or NMRI) is a non-invasive technique that uses the phenomenon of nuclear magnetic resonance to obtain information about the structure and composition of the body to be analyzed. This information is processed by computers and transformed into images inside what has been analyzed.

It is mainly used in medicine to observe alterations in tissues and detect cancer and other pathologies. It is also used industrially to analyze the structure of both organic and inorganic materials.

MRI should not be confused with nuclear magnetic resonance spectroscopy, a technique used in chemistry that uses the same principle of magnetic resonance to obtain information about the composition of materials.

Unlike computerized axial tomography (CT), it does not use ionizing radiation, but magnetic fields to align the nuclear magnetization of (usually) hydrogen nuclei of water in the body. These nuclei resonate at a frequency proportional to the magnetic field exerted so that a radiofrequency (RF) fields can be applied to systematically alter the alignment of the spins of that magnetization, causing the hydrogen nuclei to produce a rotational magnetic field detectable by the scanner. That signal can be manipulated with additional magnetic fields and thus build more images of the body

good thing- during decomposition the organic molecules in organic matter are broken down into simpler organic molecules that require further decomposition or into mineralised nutrients

bad thing- it can be harmful in crop productivity

the answer is c cumulus. cumulus clouds can be seen on a gray and rainy day, because cumulus clouds create thunderstorms. give me brainliest if right.
