Answer:
The correct answer is ''the mechanisms for coordinating subunits.''
Explanation:
Integration mechanisms are explicitly defined to coordinate subunits. In turn, are divided into structural and non-structural mechanisms. Structural integration mechanisms coordinate activities and are usually linked to specific management positions or bodies. The non-structural integration mechanisms, for their part, are characterized because they do not create organs or positions, but they constitute a relevant complement to the structural mechanisms, facilitating the organization of work. Informal integration mechanisms or those aimed at facilitating informal relationships are the simplest and easiest to use. Individuals face a certain situation and, spontaneously, communicate with each other. If no further coordination is required, informal mechanisms may be sufficient

cd4+ T helper (Th) cells include Th1, Th2, and Th17 cells. They contribute to aliergic reactions and fighting extracellular parasites.
Answer:
The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. ... The absorbed energy warms the atmosphere and the surface of the Earth.
