2. Is a protein - which is a polymer of amino acids. They generally have the suffix -ase- like lactase.






3. Are membrane-bound organelles that contain digestive enzymes that digest dead or unused material within the cell or materials absorbed by the cell for use.






4. The pituitary gland.






5. Are the monomers that form nucleic acids - containing a sugar - phosphate group - and a nitrogenous base.






6. Are more closely related to Homo Sapiens than to other apes - but Homo Sapiens did not evolve from chimpanzees.






7. Layer that will become the skin - some endocrine glands - and the nervous system.






8. Occurs when an individual from an adjacent population of the same species immigrates and breeds with a member of a previously locally isolated group - resulting in a change in the gene pool.






9. High temperatures






10. Are easily converted to ATP - but the main energy products of the Krebs cycle liberate electrons then used in the electron transfer reactions.






11. Developed by the German scientists Schleiden and Schwann - States that all living things are made of cells - cells are the basic units of life - all cells come from pre-existing cells.






12. Is found in the root cap and is responsible for quick growth in the roots.






13. Produce seeds without flowers. They include conifers (cone-bearers) and cycads.






14. Veins in the leaf and are also distributed throughout the stem






15. Super-class of vertebrae including organisms with no jaws.






16. Some patrol the blood for antigens - but are also equipped to destroy antigens. They may regulate immune responses as well.






17. Subsets below the kingdom level






18. Is a compound fruit that forms from several ovaries of separate flowers that fuse together during ripening (strawberry - or pineapple).






19. Enzymes are usually __________ to certain reactions.






20. Are the organelles where cellular respiration occurs.






21. Process in which elements - chemical compounds - and other forms of matter are passed from one organism to another and from one part of the biosphere to another.






22. Super-class of vertebrae including organisms with jaws.






23. Is found on the stem between nodes.






24. Fossilized burrows from multicellular organisms begin to appear in the geological record approximately 700 million years ago during the Precambrian period. These multicellular animals had only soft parts and could not be fossilized.






25. Develops from the morula as a thin layer of cells surrounding an internal cavity.






26. When the water concentration inside and outside the cell is equal - It is said to be in an...






27. Controls balance and muscle coordination






28. Carbon - nitrogen - phosphorous - and water. These are all recycled through biogeochemical processes.






29. Are formed when the plasma membrane of a cell encloses a molecule outside the membrane - then releases a membrane bound sack containing the desired molecule into the cytoplasm. This process allows the cell to absorb molecules that are larger in size






30. Process of breaking down complex materials (foods) to form simpler substances and release energy.






31. Stood upright before there was an increase in brain size.






32. Fruits that develop from a single ripened ovary (apple - olive - acorn - cucumber).






33. The physical place where a particular organism lives. It must include all the factors that will support its life and reproduction.






34. Is the waxy protective outer coating of leaves.






35. Chlorophyll pigments absorb photons of light - leaving the chlorophyll in a higher energy (excited) state - these then supply energy to reactions that produce ATP from ADP and Pi.






36. Is a social behavior of an organism that is beneficial to the group at the individual's expense.






37. Contains the chromosomes and is the site of reproduction through mitosis and meiosis.






38. Respiratory organs within insects






39. Is a substance that changes the speed of a reaction without being affected itself.






40. Is a behavior that is learned during a critical point (often very early) in an individual's life. Imprinting enables the young the recognize members of their own species.






41. Is a special protein that acts as a catalyst for organic reactions.






42. Is the number of organisms that can be supported within a particular ecosystem.






43. The destruction of gametes - (sex cells such as sperm and eggs).






44. Is a phylum that contains sponges.






45. Is a coenzyme required in the synthesis of collagen.






46. Must be present for photosynthesis to occur - it is not used up in the process.






47. Mass extinctions promote diversification because _______________ - making conditions favorable for the establishment of new - diverse species.






48. The role played by an organism in its food chain.






49. When stems bend toward the light it is due to _____________ the hormone auxin - in response to light - migrates from the light to the dark side of the shoot tip. The cells on the dark side now contain more auxin - which causes the cells on that side






50. Is a phylum that contains jellyfish - hydra - etc.
