Make your wager and hand it to the teacher
Final Question
• Name three functions of the skin and explain how it performs the function.
• Mechanical Damage - It makes a physical barrier. Outer layers has cells that contain keratin, which toughens the cells and has pressure receptors, which alert the body of potential damage
• Chemical Damage - Once again the keratinized cells block chemicals and pain receptors alert the body
• Bacterial Damage - Block the bacteria, but also the skin’s secretion are acidic (inhibit growth) and skin cells have phagocytes (eat the bacteria)
• Ultraviolet Radiation - Contains melanin that offers protection from UV damage
• Thermal Damage - Contains hot, cold, and pain receptors that alert the body
• Desiccation (Drying Out) - Contains waterproofing glycolipid and keratin
• Aids in heat loss (activates sweat glands and allows blood to flow closer to surface) and heat retention (stops blood from rushing to surface)
• Aids in excretion of urea and uric acid (makes up some of your sweat)
• Synthesizes vitamin D (uses sunlight to convert some cholesterol molecules to vitamin D)
Final Final Question
• Why would it not be wise to only have hair as evidence if you were trying to prosecute a defendant in court?
Answer
• Hairs within a species can have similar qualities. Therefore, different people can have similar hairs. Also, hairs vary from hair to hair on the same person, so one can never definitively say if a hair came for a certain person; all that can be said is it is similar to the person’s hair.
