Subjects : sat, science, biology
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. An air-conducting tube






2. Self-digestion occurring in plant and animal tissues - particularly after they have ceased to function properly






3. Involuntary muscle






4. The organelle that provides mechanical support and carries out motility functions for the cell






5. An undifferentiated - growing region of a plant that is constantly undergoing cell division and differentiation






6. A ring-shaped muscle that is capable of closing a tubular opening by constriction






7. An opening in the eye whose size is regulated by the iris






8. A network of capillaries in the Bowman's capsules of the kidney






9. A mitotic stage in which nuclei reform and nuclear membrane reappears






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






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






12. The male gonads that produce sperm and male hormones






13. The microspore of a seed plant






14. A short - stubby rod consisting of chromatin that is found in the nucleus of the cells; contains the genetic or hereditary component of cells (in the form of genes)






15. The part of the body of an animal that is between the neck or head and the abdomen






16. A structure of the eye that focuses images on the retina by changing its convexity






17. The functional role and position of an organism in an ecosystem; embodies every aspect of the organism's existence






18. An enlargement of the thyroid gland due to lack of iodine






19. Daily cycles of behavior






20. A mall sex hormone (e.g. - testosterone)

24. Functional urinary tubules responsible for excretion in the kidney of vertebrates






25. A hormonal secretion of the adrenal cortex






26. A wall composed of cellulose that is external to the cell membrane in plants; it is primarily involved in support and in the maintenance of proper internal pressure

31. The thin-walled anterior chamber of the heart (also called the auricle)






32. A period in the development of animals between the embryo and adult stages; starts at hatching and ends in metamorphasis






33. An organelle that regulates cell functions and contains the genetic material of the cell






34. A plant that lives on another plant mensalistically






35. A family tree depicting the inheritance of a particular genetic trait over several generations






36. The pigment in rod cells that causes light sensitivity






37. The orientation of cells or organisms in relation to chemical stimuli; the growth or movement response of organisms to chemical stimuli






38. Degree of penetrability - as in membranes that allow given substances to pass through; the ability to penetrate






39. A marine arthropod - now extinct - that lived during the Paleozoic era






40. In taxonomy - a classification between species and family






41. An organelle in the cytoplasm that contains RNA; serves as the site of protein synthesis






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






43. Any chromosome that is not a sex chromosome






44. A colloidal system involving the dispersion of a liquid within a liquid

46. The state in which two genetic traits are fully expressed and neither dominates






47. The physical appearance or makeup of an individual - as opposed to its genetic makeup






48. A specialized structure that carries out particular functions for eukaryotic cells






49. A space in the body
