Across
  1. 5. Early mitotic divisions restricted to the animal pole.
  2. 7. The emergence of individual and behavioral characteristics through growth processes over time.
  3. 9. Organisms are more than just the products of genes
  4. 10. Includes bones divided into skull, vertebral column, and thoracic case regions.
  5. 14. Specialized type of calcification unique to vertebrates
  6. 19. Specialized connective tissue in which calcium phosphate and other organic salts are deposited in the matrix.
  7. 22. The change in time at which a characteristics appears in the embryo relative to its appearance in a phylogenetic ancestorparturition is the act of giving birth via viviparity.
  8. 23. Known as bone breakers
  9. 26. The genetic mak-up of an individual a
  10. 27. Vertebrates laying eggs encapsulated in such shells or other tertiary egg envelopes.
  11. 28. Changes in an organism from zygote to death
  12. 30. A pole where most yolk resides.
  13. 32. Are the cells resulting from these early cleavage divisions of the ovum.
  14. 33. Composed of more than one layer of cells
  15. 35. Early embryonic stage during which the basic gut is formed
  16. 36. Known as bone makers
  17. 38. Vertebrates giving birth to embryos without such shells.
  18. 39. Wherein a feature grows longer, grow faster or begins development
Down
  1. 1. A solid ground substance that is effective in resisting compressive forces.
  2. 2. Solid ball of cells from division of a fertilized ovum.
  3. 3. Male gamete
  4. 4. Tiny spaces where “osteocytes” is found
  5. 6. Early mitotic divisions restricted to the animal pole.
  6. 8. Radical and abrupt postembryonic change in structure
  7. 11. Vertebrates whose embryos possess extraembryonic membranes
  8. 12. Cylindrical structure that provides strength and support to bone.
  9. 13. Pertaining to eggs that contain small quantities of stored yolk.
  10. 15. If they resemble juveniles of their ancestor. It exhibit early offset, grow slower, or begin development relatively late.
  11. 16. Where separate bone or cartilage elements make contact.
  12. 17. Pertaining to eggs with large quantities of stored yolk.
  13. 18. A composite structure formed in part from tissues of the fetus and in part from tissues of the mother.
  14. 20. Phase of embryonic development that starts at the end of gastrulation and continues until birth.
  15. 21. Without amnion, include fishes and amphibians
  16. 24. Firm but flexible special connective tissue
  17. 25. Type of mineralization occurs early during bone development, bone repair and in some fishes.
  18. 29. Formed closely of adjoined cells with very little extracellular matrix between them.
  19. 31. Cells specialized to secrete a product
  20. 34. Stimulates the other germ layers to form parts of organs.
  21. 37. Female gamete
