1. Sex-linked recessive disorder carried on the x chromosome defined by the absence of one or more proteins required for blood clotting






2. Is made of stacked cells connected by sieve plates that allow nutrients to pass from cell to cell. They transport food made in the leaves (by photosynthesis) to the rest of the plant).






3. The preservation of the integrity of genetic information from one generation to another.






4. Attaches to an enzyme and blocks the enzyme reaction rather than enhancing it - like a prosthetic group would.






5. Engages in both passive and active transport.






6. Are cells involved in immunity and are produced in bone marrow as stem cells.






7. Contains organisms that are multicellular eukaryotes including molds and mushrooms.






8. A length of DNA (with corresponding histones) is responsible for the production of a certain protein that causes a particular trait to be expressed in an organism.






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






10. Is more like branching out of a tree with dead ends and new branches appearing simultaneously than like steps on a ladder.






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






12. A suffix meaning 'to break apart.' O || ||






13. The systematic search for individuals with a specific genotype in a delineated population.






14. The individual we recognize as an adult fern.






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






16. A reaction that adds water to another compound. (2 hydrogens - 1 oxygen).






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






18. The phyla composed of segmented worms.






19. This is a carboxyl group and is the signature group found within organic acids.






20. The process of forming eggs and sperm cells in the reproductive organs.






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






22. Is the organelle where cellular reproductive processes occur.






23. Produce adrenaline. This hormone is a well-known constrictor of blood vessels.






24. The solid mass of cells resulting from the cleavage of the ovum before the formation of a blastula.






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






26. The bronchi lead to the two lungs where they branch out in all directions into smaller tubules known as bronchioles.






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






28. In DNA Thymine pairs with...






29. Respiratory organs within insects






30. Inorganic phosphate






31. Protein synthesis






32. Decomposition of living matter for consumption.






33. Becomes available for erosion as undersea sedimentary rocks are up-thrust by volcanic activity - erosion releases it from rocks into streams where it combines with oxygen to form phosphates in lakes that are then absorbed by plants - it is recycled t






34. Is a disease caused by lack of vitamin C in which the body is unable to build enough collagen (a major component of connective tissue).






35. Absorb a photon of light and is found in the grana of the chloroplast.






36. All store energy within their chemical bonds.






37. Covers and protects the leaf.






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






39. Some enzymes contain a __________ component that is essential to their functions.






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






41. The size of a cell is limited by the ratio of its surface area to volume.






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






43. The phyla of sponges.






44. Is found on the stem between nodes.






45. Is an accidental change of the DNA sequence of the gene that can result in creating a change of trait that is not found in the parent.






46. 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.






47. Is an abundant element found in protoplasm. Together with oxygen - hydrogen - and nitrogen - it composes over 90% of cellular structure.






48. Biotic (living) factors such as population and food source - and abiotic (non-living) factors such as weather - temperature - soil features - sunlight).






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. Algae and Protozoa belong to the kingdom...
