Question

question 2 (bonus) (mandatory) (1 point) for the same picture in #1, what specific structure is the arrow pointing to?
○ elastic tissue
○ reticular fiber
○ collagen fiber
○ elastic fiber

Explanation:

Assuming the image (from question #1, though not shown here) depicts a structure with elastic properties, elastic fibers are part of connective tissue structures (like in elastic cartilage or other tissues with elasticity). Among the options, elastic fiber is a specific structural component (while elastic tissue is a tissue type, and collagen/reticular fibers have different structural roles). So the arrow likely points to elastic fiber.

Answer:

elastic fiber
