(a)
To determine:
The similarities and dissimilarities between characteristics of hemorrhagic and non-hemorrhagic fever diseases.
Concept introduction:
Cardiovascular system also is known as circulatory system is a system which allows blood to flow throughout the body and transports nutrients, gases and other important enzymes in and out of the cells. It is composed of two components: Heart and the blood vessels. This system is highly protected from infections but microbes that successfully invade the system acquire entrance to many body parts affecting every system.
(b)
To provide:
The explanation for the observed increase in the incidence of these zoonotic infections around the world today.
Concept introduction:
Zoonoses are those animal diseases that are transmitted to humans. These diseases could be viral, bacterial fungal or

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.
