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 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.






2. Is found on the stem between nodes.






3. Is the number of organisms that can be supported within a particular ecosystem.






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






5. Is secreted by the adrenal cortex to promote sodium reabsorption in the kidney.






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






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






8. Most fossils of Hominids are from continents other than...






9. Breaking down






10. Covers and protects the leaf.






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






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






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






14. 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).






15. Consists of undifferentiated cells capable of quick growth and specialization. It is responsible for elongation of the stem.






16. 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).






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






18. Is the major component of sand and is the most abundant element found in the lithosphere. It is not recycled.






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






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






21. Controls olfactory lobes (smell)






22. The phylum of insects (bees).






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






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






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






26. Protein synthesis






27. The class composed of birds.






28. Is a special protein that acts as a catalyst for organic reactions.






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






30. 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.






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






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






33. The transfer of electrons.






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






35. Transparency - polarity - high specific heat - and density (lower density when solid than when liquid.).






36. Refers to the birthrate of a population.






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






38. Is a social behavior of an organism that is beneficial to the group at the individual's expense.






39. An orienting response to light.






40. Small - green - heart-shaped gametophyte plant form of a fern that can make its own food and absorb water and nutrients from the soil






41. The phyla of sponges.






42. Is when expression of genetic traits is determined by weather the trait is inherited from the mother or the father.






43. Controls hunger and thirst






44. Are organic cofactors or coenzymes that are required by some enzymatic reactions.






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






46. 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.






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






48. 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.






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






50. Ended with the extinction of the dinosaurs.
