Question 13 (1 point) There is more water in the epidermis than in the dermis True False Question 14 (1 point) The most important molecule in the epidermis is keratin True False Question 15 (1 point) Elastin constitutes the skin's structural resource and is the most abundant protein in the human body True False

* **Question 13:** False. The dermis contains significantly more water than the epidermis. The dermis is rich in blood vessels and a gel-like substance that holds water, contributing to skin hydration and plumpness. The epidermis, being the outermost layer, is designed for protection and contains more keratin than water.<br /><br />* **Question 14:** True. Keratin is the most important molecule in the epidermis. It is a fibrous structural protein that provides strength, waterproofing, and protection against abrasion and pathogens.<br /><br />* **Question 15:** False. While elastin is crucial for skin elasticity and is a structural component, *collagen* is the most abundant protein in the human body, not elastin. Collagen provides structural support to various tissues, including skin, tendons, and ligaments. Elastin works in conjunction with collagen to give skin its flexibility and resilience.<br />
