Transcript text: Both collagen and elastin are mostly composed of - $\qquad$
Select the correct response:
skin
nerves
melanocytes
protein
Solution
The answer is the fourth one: protein.
Explanation for each option:
Skin: Skin is an organ composed of multiple layers and various cell types, but it is not a component of collagen and elastin.
Nerves: Nerves are part of the nervous system and are not the primary components of collagen and elastin.
Melanocytes: Melanocytes are cells that produce melanin, the pigment responsible for skin color, and are not related to the composition of collagen and elastin.
Protein: Collagen and elastin are both proteins. Collagen provides structural support and strength, while elastin allows tissues to resume their shape after stretching or contracting.
Summary: Collagen and elastin are primarily composed of protein.
