CLEP Biology

Subjects : clep, 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. Most fossils of Hominids are from continents other than...






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






3. What phylum are snakes in?






4. Is composed of an anterior and posterior lobe. The stalk of the lobe is connected to the hypothalamus. Antidiuretic Hormone (AH) is produced in the hypothalamus and stored in the posterior pituitary. Upon nervous stimulation from the hypothalamus - t






5. 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.






6. Plants and animals obtain usable nitrogen






7. Covers and protects the leaf.






8. The transfer of electrons.






9. Inorganic phosphate






10. In order to become an established part of an island ecosystem there must be a populations large enough to ensure _________ - a food source - a suitable habitat - and a source of moisture.






11. Has loosely packed cells that allow for gas and moisture exchange.






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






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






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






15. Proposes that those individuals within a population that are most adapted to the environment are also the most likely individuals to produce viable offspring.






16. 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.






17. The trachea includes the windpipe or larynx in its upper portion - and the glottis - an opening that allows the gases to pass into the two branches known as the bronchi.






18. Protein synthesis






19. The phyla composed of segmented worms.






20. Between the endoderm and ectoderm - layer that will eventually form the muscles - and organs of the skeletal - circulatory - respiratory - reproductive - and excretory systems.






21. Breaking down






22. Contains optic lobes - controls sight.






23. The lineage that led to the modern Homo Sapiens diverged from the lineage that led to the modern chimpanzee.






24. May be ions or non-protein molecules - they are similar to cofactors - but differ in that they are tightly attached by covalent bonds to the enzyme - rather than being separate atoms or molecules.






25. The individual we recognize as an adult fern.






26. Studied the relationships between traits expressed in parents and offspring and the genes that caused the traits to be expressed.






27. 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






28. Niche






29. Is a compound fruit that develops from many ovaries of a single flower fusing together (raspberry).






30. 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.






31. Are produced when water passes through the cell membrane by osmosis from an area of higher concentration to an area of lower concentration - to equalize water concentration.






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






33. Has an equal (50%) chance of being passed from a carrier mother to a son or a daughter.






34. Disease causing






35. Are surrounded by capillaries that allow for carbon dioxide to diffuse into the lungs and oxygen to diffuse out.






36. Allows for the genetic code to be preserved in future generations of cells.






37. Is very rare and is not absorbed by plant leaves. Phosphorous is nearly always found in solid form.






38. Has extreme cold temperatures - low precipitation - modified grassland - perma-frost - a short growing season and some plants and animals.






39. 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.






40. Is the outermost of the three main layers of an embryo.






41. Plants that produce flowers as reproductive organs. They have two divisions - monocots and dicots.






42. Is the control of protein synthesis. Genetic traits are expressed and specialization of cells occur as a result of the combination of proteins produced by the DNA of a cell.






43. Subsets below the kingdom level






44. 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.






45. Enzymes are usually __________ to certain reactions.






46. Is the sugar that lactase acts upon.






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






48. Contains many genes and is a structure comprised of linear DNA and associated proteins.






49. The phylum of insects (bees).






50. The process whereby cells build molecules and store energy (in the form of covalent chemical bonds).
