question 2 of 25
which of the following statements is true of elastin?
select the correct response:
it gives the skin its flexibility and elasticity.
it is never affected by age.
it exists separately from collagen fibers.
it is found within the stratum corneum.

Explanation:

• Analyze each option:
• "It gives the skin its flexibility and elasticity." Elastin is a protein that provides skin with flexibility and elasticity, this is correct.
• "It is never affected by age." Elastin production decreases with age, so this is false.
• "It exists separately from collagen fibers." Elastin and collagen are both in the dermis and interact, so this is false.
• "It is found within the stratum corneum." Elastin is in the dermis, stratum corneum is the outermost layer with no elastin, so this is false.

Answer:

It gives the skin its flexibility and elasticity.
