Question

1. what structures increase the surface area for absorption?

Explanation:

In biology (a subfield of Natural Science), structures like microvilli in the small intestine, root hairs in plants, and the convoluted tubules in kidneys increase surface area for absorption. Microvilli are tiny projections on intestinal cells, root hairs extend from plant roots, and convoluted tubules in nephrons fold to enhance surface area for nutrient or water absorption.

Answer:

Examples include microvilli (in small intestine), root hairs (in plants), convoluted tubules (in kidneys)
