Answer:
Tetrad.
Explanation:
Tetrads may be defined as the stage of the division in which the cell contains the four spores in case of Ascus. The tetrad condition generally occurs in the meiosis division.
Tetrad stage are exceptionally found in the cocci or round bacteria. During tetrad stage, the bacteria divides in the square planar arrangement and forms the square of the four bacteria. This arrangement of four bacteria is the tetrad stage.
Thus, the answer is tetrad.
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.

Answer:
Climate zones are areas with distinct climates, which occur in the east-west direction around the Earth, and can be classified using different climatic parameters. Due to temperature differences caused by the differences in radiation, recurring climatic conditions develop, such as winter and summer.
