Final answer:
Mrs. Jones' gelatin salad resembles connective tissue because both contain a gel-like substance that supports various elements, paralleling the ground substance in connective tissue supporting fibers and cells.
Step-by-step explanation:
Mrs. Jones' gelatin salad can be likened to connective tissue because it demonstrates the characteristic properties of a colloidal gel, similar to the extracellular matrix found in connective tissue. Gelatin itself, when cooled, forms a gel- a viscous substance that is a dispersion of a liquid within a solid matrix.
This is akin to how connective tissue has a ground substance (often compared to a gel) that supports fibers and cells, much like the shredded cabbage, sliced almonds, and raisins suspended in Mrs. Jones' gelatin.
The proteoglycans in connective tissue also trap moisture, creating a viscous, colorless matrix known as ground substance, further enhancing the metaphor between her salad and connective tissue.
