This is known as the pericardium
Food is chewed in the mouth because it helps you break down larger particles of food into smaller particles this well help in swallowing and digesting your food. Without being able to chew it is most likely for you to get constipated or choke
Answer:
Nuclear magnetic resonance (NMR) technology can penetrate materials without destroying samples, and has the advantages of fast, accurate and high resolution. As a means of studying material properties, it has been widely used in the fields of environment, medical imaging, material structure identification, biochemical analysis, food analysis, coal chemistry, soil science and so on. In the field of soil science, the carbon in soil organic matter samples from forest surface was analyzed by solid NMR technology Dignac, etc. With the help of various experimental techniques, the functional relationship between carbon-nitrogen ratio and element content was obtained, and the change rule of carbon-nitrogen content was confirmed in specific areas. In medical imaging, image formation is the spatial distribution of longitudinal relaxation time and transverse relaxation time and the display of nuclear density reflected by NMR signals. In the field of polymer materials, NMR technology can be used to study the adsorption, desorption and diffusion of polymers in solvents containing different particles. In the field of environment, nuclear magnetic resonance (NMR) has shown its unique importance in studying water uptake in soil and soil wettability.

"The advantage of interferometry for optical astronomers is that it can provide measurements of stars with a higher angular resolution than is possible with conventional telescopes. ... An optical interferometer does not produce direct images of stars and typically has only a rudimentary ability to make images.
