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. The phyla composed of segmented worms.






2. Is the process that releases energy for use by the cell.






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






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






5. 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.






6. Algae and Protozoa belong to the kingdom...






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






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






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






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






11. 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






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






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






14. The total amount of genetic information available for a given species.






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






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






17. Cleave strands of DNA segments at certain sites.






18. 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






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






20. The number of organisms in a given community - can be above or below the carrying capacity.






21. Enzymes are usually __________ to certain reactions.






22. All store energy within their chemical bonds.






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






24. The effect of a substrate concentration on the initial reaction rate in the presence of a limited amount of enzyme: _________________ as the concentration of substrate is increased until all the enzymes are used - then the reaction rate will level of






25. 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).






26. Can be accounted for by the theory of punctuated equilibrium. The fossil record shows periods of stability with regard to appearance and disappearance of species as well as periods of sudden change.






27. Is comprised of all the organisms that interact within a given ecosystem whether or not it is at carrying capacity.






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






29. Controls olfactory lobes (smell)






30. Layer that will become the gut lining as well as some accessory structures.






31. 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.






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






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






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






35. 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.






36. Include: Vascular tissue - including both xylem and phloem - and sieve plates existing between cells of the stem.






37. Subsets below the kingdom level






38. Decomposition of living matter for consumption.






39. 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.






40. 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.






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






42. 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.






43. 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.






44. Produces the most ATP molecules - yielding 34 ATPs per glucose molecule.






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






46. Occurs when two populations are geographically isolated from each other. Over time this results in the production of two separate species.






47. 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.






48. Is the earliest period of the Paleozoic era. Began with the Cambrian explosion - this explosion of life resulted in the representatives of most of the modern phyla being present.






49. Is found on the stem between nodes.






50. Anabolism
