  1. 3. a part of an organism which is typically self-contained and has a specific vital function.

  3. 8. the resistance that one surface or object encounters when moving over another.
  4. 11. a flexible but inelastic cord of strong fibrous collagen tissue attaching a muscle to a bone.
  5. 13. a warm-blooded vertebrate animal of a class that is distinguished by the possession of hair or fur, females that secrete milk for the nourishment of the young, and (typically) the birth of live young.
  6. 15. the refusal to accept or comply with something
  7. 17. relating to or requiring an absence of free oxygen.
  8. 19. the study of the properties of moving air and the interaction between the air and solid bodies moving through it.
  9. 20. the inner and typically larger of the two bones between the knee and the ankle parallel with the fibula.
  10. 21. each of the pair of organs situated within the rib cage, consisting of elastic sacs with branching passages into which air is drawn, so that oxygen can pass into the blood and carbon dioxide be removed.
  11. 23. something pledged as security for repayment of a loan, to be forfeited in the event of a default.

  10. 16. firm, flexible connective tissue found in various forms in the larynx and respiratory tract, in structures such as the external ear, and in the articulating surfaces of joints. It is more widespread in the infant skeleton, being replaced by bone during growth.
  11. 18. the application of scientific knowledge for practical purposes, especially in industry.
  12. 22. the ability of an object or material to resume its normal shape after being stretched or compressed; stretchiness.
