The Physiology and Biochemistry of the Digestion System of Termites from the Genus Anacanthotermes Jacobson, 1904
Bibliographic record
Abstract
A variety of morphological and functional features of the digestive system of termites is associated with their nutritional adaptation. Wood is mostly the food of termites’ adult larvae, workers and young nymphs. The salivary and intestinal enzymes play an important part in this process. The physiology and biochemistry of the digestion system of termites from the genus Anacanthotermes is still not fully studied. In the present research, we studied the activity of some carbohydrases in termites’ salivary glands. Our data show that the activity of exocellulase in adult termites is 1.5 times more that in young individuals and 3 times more active than in nymphs, while the exocellulase in soldiers remains inactive. Moreover, the activity of celluloses in the intestine of A. turkestanicus is still not fully studied. We observed that exocellulase is involved in the digestion of food polymers in the castes of termites-workers, nymphs and soldiers. Thus, cellulase activity in the intestinal tissue (intrinsic) is manifested at a very low level in all termites’ castes we studied. However, the activity of exocellulase in the intestinal cavity (symbiotic) increases 3.5 times in workers, 3.0 times in nymphs and 2.4 times in soldiers compared to that in intestinal tissue. In addition, the intrinsic activity of this enzyme differed little in all three castes of termites, whereas the symbiotic activity in workers and nymphs was more showed than in soldiers.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
