Answer:
The hair is made up of 95% keratin, a fibrous, helicoidal protein (shaped like a helix) that forms part of the skin and all its appendages (body hair, nails, etc.). Keratin is synthesized by keratinocytes and is insoluble in water, thus ensuring impermeability and protection for the hair.

This exercise is incomplete, missing the value of k (decay constant), which is equal to 4x10⁻⁸s⁻¹ at 25°C
The answer is 0.549 years
Explanation:
Given:
first order of reaction
k = 4x10⁻⁸s⁻¹
For a first order of reaction, the half-life time for the degradation of DDT is equal to:
The correct answer would be DIFFUSION. The mechanism that controls water changes in the cells by the movement of water from an area of high water concentration to an area of low water concentration is called Diffusion. This mechanism continues until there is balance in the water concentration. On the other hand, Osmosis is the movement of water from an area of low water concentration to an area with high water concentration.
The two sources within a medical record where the information about present or recent illnesses is most likely to be found are the lab reports and the physician's order. The medical history and physical examination sections of the medical record should contain information about present illnesses. Other possible sources of information are patient referral letters, the discharge summary, and the operative report.
