1. Briefly explain how does the body maintain homeostasis? Homeostasis is a existence and maintenance of a relatively constant internal environment. Homeostasis is maintain by negative and positive feedback mechanism. Most homeostatic control mechanisms are negative feedback mechanisms. In these system‚ the output shut off the original stimulus or reduce its intensity. These mechanisms cause the variable to change in a direction opposite to that of the initial change‚ returning it to its “ideal”

SOLUTION TO ANDREW–CARTER‚ INC.‚ CASE This case presents some of the basic concepts of aggregate planning by the transportation method. The case involves solving a rather complex set of transportation problems. Four different configurations of operating plants have to be tested. The solutions‚ although requiring relatively few iterations to optimality‚ involve degeneracy if solved manually. The costs are: [pic] The lowest weekly total cost‚ operating plants 1 and 3 with 2 closed‚ is
