Explanation:

Question 71

The skin has three main layers: the epidermis (outermost, thinnest), dermis (middle), and subcutaneous (innermost). Option a "surface" is not a specific skin layer. Option b "subcutaneous" is the innermost. Option c "dermis" is the middle layer. So the outermost and thinnest is the epidermis.

The EPA (Environmental Protection Agency) designates disinfecting agents for hospital use and blood/body fluid cleaning. DOL (Department of Labor) deals with labor issues, CDC (Centers for Disease Control and Prevention) focuses on disease prevention, OSHA (Occupational Safety and Health Administration) on workplace safety. So EPA is responsible.

Answer:

d. epidermis
