Final answer:
Elastin fibers give the most when stretched in connective tissues.
Step-by-step explanation:
The tissue component that gives the most when stretched is Elastin. Elastin fibers are a type of protein fiber found in connective tissues. These fibers are thin and elastic, allowing them to stretch and then return to their original shape. Collagen fibers, on the other hand, have great tensile strength and resist stretching.
Ground substance refers to the fluid or gel-like substance that fills the spaces between cells and fibers in connective tissues. Osteoblasts are bone cells that are involved in bone formation, but do not contribute directly to tissue stretching.
