What would be the protein needs of a man named Josh who exercises moderately and is the same age and size as Wayne? Josh is 5 ft, 8 in tall and weighs 183 lb. Round the number of grams to the nearest whole number. During calculations, use numbers rounded to the first decimal place. Because protein requirement is a range, please enter two numbers: lower and upper range values, respectively.

Current treatments are focused on highlyactive antiretroviral therapy (HAART). HAART usually consists of an orally delivered drug cocktail containingtwo different reverse transcriptase inhibitors and one other drug, such as a protease inhibitor. Question: Develop a pharmacokinetic model of HAART treatment. Consider all 3 drugs. Make sure to include adiagram that illustrates your thinking, state all assumptions, and define your variables.
