9. The largest portion of the human brain; it is believed to be the center of intelligence - conscious thought and sensation






10. In plants - the tissue between the epidermis and the vascular cylinder in the roots and stems of plants; in animals - the outer tissue of some organs






11. Nonfunctional haploid cells created during meiosis in females; they have very little cytoplasm-most has gone into the functional egg cell






12. A stage of embryonic development characterized by the differentiation of the cells into the ectoderm and endoderm germ layers and by the formation of the archenteron






13. A mitotic or meiotic stage in which the chromosomes become visible and during which the spindle fibers form; synapsis takes place during the first meiotic prophase






14. The phylum to which jointed-legged invertebrates belong - including insects - arachnids and crustaceans






15. The place of attachment of the mitotic fiber to the chromosome






16. A mucus-secreting membrane






17. An animal with a constant body temperature






18. A kind of microorganism that is between a virus and a bacterium; parasitic within the cells of insects and ticks






19. An organic compound to which hydrogen and oxygen are attached; the hydrogen and oxygen are in a 2:1 ratio; examples include sugars - starches and cellulose






20. A process of photosynthesis in which water is split into H+ and OH-; the hydrogen ion is then joined to NADP






21. The science of classification of living things






22. A fatty sheath surrounding the axon of a neuron that aids in stimulus transmission; it is secreted by the Schwann cells






23. A hormone that stimulates plant stem elongation






24. Usually referred to as ACTH and secreted by the anterior lobe of the pituitary gland; stimulates the adrenal cortex to produce its characteristic hormones






25. An air-conducting tube






26. A microscopic opening located in the epidermis of a leaf and formed by a pair of guard cells

28. The colored part of the eye that is capable of contracting and regulating the size of the pupils






29. A sex or reproductive cell that must fuse with another of the opposite type to form a zygote






30. An organism that produces spores; a phase in the diploid-haploid life cycle that alternates with a gametophyte phase






31. Adenosine diphosphate (ADP) and adenosine triphosphate (ATP) - which are energy storage molecules






32. In mammals - the slitlike opening formed by the vocal folds in the larynx






33. Nonliving - as in the physical environment






34. The most anterior portion of the small intestine of vertebrates - adjacent to the stomach; the continuation of the stomach into which the bile duct and pancreatic duct empty






35. A fat-digesting hormone






36. Partially digested food in the stomach






37. The pairing of homologous chromosomes during meiosis






38. A hoofed animal






39. A form of anaerobic respiration found in yeast and bacteria






40. A duct that carries urine from the kidneys to the bladder






41. A bone of the upper arm






42. A four-letter code made up of the DNA nitrogen bases A - T - G and C; each chromosome is made up of thousands of these bases






43. A nerve fiber






44. A dense fluid within the chloroplast in which CO2 is converted into sugars in photosynthesis






45. Any organism that is the victim of a parasite






46. Tubules that excrete metabolic wastes into the hindgut in arthropods






47. An organism that is heterozygous for two different traits






48. An air duct from the middle ear to the throat that equalizes external and internal air pressure






49. The loss of all or part of a chromosome






50. The part of the flower that bears the female gametophyte
