<span>Villi are hair-like structures covered with epithelial cells measuring 1.5 mm that line the mucous inner membrane of the small intestine. The epithelial cells of the villi contain microvilli and are responsible for the absorption of nutrients. Being so small and numerous, they effectively increase the absorptive surface area of the small intestine. When the surface area increases, this is the time they absorb the nutrients.
As for plants' root hair cells, they receive nutrients through osmosis. Root hair cells are adapted for this by having a large surface area to speed up osmosis. The absorbed water and minerals are transported through the roots to the rest of the plant where it is used for different purposes: It is a reactant used in photosynthesis.
As we can see, both of them utilize increasing their surface area.</span>
Answer:
These are things that won't be going away. Natural gasses and fossil fuels will likely run out someday or become much harder to find. When you use these sources of energy, they won't be going away and therefore will be sustainable because we can always continue using them.
Does that make sense?
Explanation:
Not quite sure but would say Archaebacteria with the most confidence... hope this helps good luck

Answer:
Every living organism starts with a cell which is the fundamental units of life, an organism could be unicellular or multicellular depending on the complexity. The aggregation of cells forms tissue, the tissue makes the organ while the organ makes the entire system which forms the entire living organism.
