Answer:</h2>
<em><u>Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds</u></em>

Nicole was as diagnosed with Leigh Syndrome (LS). Leigh syndrome is said to be “a severe neurological disorder that is characterized by the degeneration of the central nervous system and is associated with a nuclear mutation in the SURF1 gene”. Which leads to a defect in a protein found in the mitochondria. It affects a protein normally found in cellular organelles, most likely the Mitochondria organelle which is involved in energy production. The aforesaid syndrome is passed down through autosomal recessive conditions. In the case of Kenneth and Vicki (Nicole’s parents), both of them may have working and nonworking copies of the gene and unfortunately, both of them passed down the nonworking gene to Nicole.

The ileum has <span>plicae circulares</span>, villi and microvilli, that are folds and projections of the mucosa layer of the ileum, that increase the surface area of food absorption. The mucosa and the submucosa of the stomach have inner folds called rugae that increase the surface areas in which food is digested by enzymes.
Plants have root hairs in their tap roots that also increase the surface area for which they absorb water and nutrient from the soil. Fibrous roots have a mesh-like a network that also increases the surface area for increased absorption.
