Across
  1. 4. - The first part of the small intestine.
  2. 6. - The part of the alimentary canal that connects the throat to the stomach; the gullet. In humans and other vertebrates it is a muscular tube lined with mucous membrane.
  3. 7. - A microorganism, especially a bacterium causing disease or fermentation.
  4. 9. - The act of chewing food
  5. 12. - The second stomach of a ruminant, having a honeycomb-like structure, receiving food from the rumen and passing it to the omasum.
  6. 16. - A short microscopic hairlike vibrating structure found in large numbers on the surface of certain cells, either causing currents in the surrounding fluid, or, in some protozoans and other small organisms, providing propulsion.
  7. 19. - Membrane-enclosed organelles that contain an array of enzymes capable of breaking down all types of biological polymers—proteins, nucleic acids, carbohydrates, and lipids.
  8. 20. - An increase or decrease in the magnitude of a property (e.g. temperature, pressure, or concentration) observed in passing from one point or moment to another.
  9. 22. Apparatus - A complex of vesicles and folded membranes within the cytoplasm of most eukaryotic cells, involved in secretion and intracellular transport.
  10. 24. - A space or vesicle within the cytoplasm of a cell, enclosed by a membrane and typically containing fluid.
  11. 25. - The process of breaking down food by mechanical and enzymatic action in the alimentary canal into substances that can be used by the body.
  12. 27. - An even-toed ungulate mammal that chews the cud regurgitated from its rumen. The ruminants comprise the cattle, sheep, antelopes, deer, giraffes, and their relatives.
  13. 29. - The spreading of something more widely.
  14. 30. - Any of a large group of organic compounds that includes sugars, starch, and cellulose, containing hydrogen and oxygen in the same ratio as water (2:1) and used as structural materials and for energy storage within living tissues.
  15. 31. - The tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes.
  16. 32. Acid - A complex organic substance present in living cells, especially DNA or RNA, whose molecules consist of many nucleotides linked in a long chain.
  17. 34. - The central and most important part of an object, movement, or group, forming the basis for its activity and growth.
Down
  1. 1. - The section of the small intestine between the duodenum and the ileum.
  2. 2. - The fourth stomach of a ruminant, which receives food from the omasum and passes it to the small intestine.
  3. 3. - Pouch or large tubelike structure in the lower abdominal cavity that receives undigested food material from the small intestine and is considered the first region of the large intestine.
  4. 5. - The muscular third stomach of a ruminant animal, between the reticulum and the abomasum.
  5. 8. - A minute particle consisting of RNA and associated proteins found in large numbers in the cytoplasm of living cells. They bind messenger RNA and transfer RNA to synthesize polypeptides and proteins.
  6. 10. - A small dense spherical structure in the nucleus of a cell during interphase.
  7. 11. - Large, complex molecules that play many critical roles in the body.
  8. 13. - An interaction of a subject with an event or entity which involves perception but not necessarily cognition.
  9. 14. reticulum - A network of membranous tubules within the cytoplasm of a eukaryotic cell, continuous with the nuclear membrane. It usually has ribosomes attached and is involved in protein and lipid synthesis.
  10. 15. - A process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane
  11. 17. Transport - The movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy.
  12. 18. - Any of a group of organic compounds which are essential for normal growth and nutrition and are required in small quantities in the diet because they cannot be synthesized by the body.
  13. 21. - The first stomach of a ruminant, which receives food or cud from the esophagus, partly digests it with the aid of bacteria, and passes it to the reticulum.
  14. 23. - Any of a class of organic compounds that are fatty acids or their derivatives and are insoluble in water but soluble in organic solvents. They include many natural oils, waxes, and steroids.
  15. 26. - The opening in the lower part of the human face, surrounded by the lips, through which food is taken in and from which speech and other sounds are emitted.
  16. 28. - A slender threadlike structure, especially a microscopic appendage that enables many protozoa, bacteria, spermatozoa, etc. to swim.
  17. 33. - The third portion of the small intestine, between the jejunum and the cecum.
