The ultrasound features associated with the highest risk for cancer include a heterogeneous echotexture, calcifications, no hilus, a rounded appearance, cystic changes, and chaotic hypervascularity. These lymph nodes should always be biopsied even in the absence of a malignant-appearing thyroid nodule [13].
The reactants in the equation for cellular respiration are oxygen (O2) and glucose (C6H12O6).he main reactants of cellular respiration are: glucose(C6 H12 O6), water(6H2 O) and oxygen(6O2). The products of cellular respiration are: carbon dioxide (6C O2), water(12H2 â¦ O) and Energy (36 ATP).
Photosynthesis and cellular respiration are said to be reverse chemical processes because the reactants of photosynthesis are the products of cell respiration and the reactant â¦ s of cell respiration are the products of photosynthesis.ecause the reactants required for cellular respiration (glucose and oxygen) are the products of photosyntheses And the and the products of cellular respiration (carbon dio â¦ xide and water) are the reactants of photosynthesis.
