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






2. A type of innate behavior (instinct.) The FAP is a preprogrammed response to a particular stimulus (known as a releaser stimulus). FAP's include courtship behaviors and feeding of young. These are not learned behaviors - they are automatically perfor






3. A sex-linked recessive disorder carried on the x chromosome in which an individual cannot perceive certain colors.






4. Is a kind of plain characterized by a warm climate - grassland - and seasonally dry climate conditions.






5. Is disorganized - unravelled - DNA with histones attached.






6. Attaches to an enzyme and blocks the enzyme reaction rather than enhancing it - like a prosthetic group would.






7. It secretes saliva which enters the digestive tract and aids the digestive process.






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






9. Where protein synthesis occurs. They float unattached in the cytoplasm. They contain RNA that is specific to their function in protein formation.






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






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






12. In DNA Thymine pairs with...






13. Produce antibodies into the bloodstream that find and attach themselves to foreign antigens (toxins - bacteria).






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






15. A cell will only remain stable if the surface area of the plasma membrane maintains a __________ with the volume of the cytoplasm.






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






17. 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.






18. Contain organisms that are multicellular eukaryotes including vertebrates and invertebrates.






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






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






21. Controls balance and muscle coordination






22. Is composed of a double layer (bilayer) of phospholipids with protein globules imbedded within the layers. The construction of the membrane allows it to aid the function of the cell by permitting entrance and exit of molecules as needed by the cell.






23. Is an ion that binds to an enzyme making it more able to catalyze a reaction.






24. 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.






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






26. An enzyme is unaffected by the reactions it catalyzes






27. The part of the earth that contains all living things - including the atmosphere (air) - the lithosphere (earth) - and the hydrosphere (water).






28. The transfer of electrons.






29. Enzymes are usually __________ to certain reactions.






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






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






32. Is the outermost layer of cells of the stem.






33. 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.






34. (of some plants or fungi) feeding on dead or decaying organic matter






35. High temperatures






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






37. An opportunistic life strategy strategy. Lichens invading a bare rock area after a volcanic eruption is an example.






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






39. The role played by an organism in its food chain.






40. 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.






41. Assumes that there are periods of stability during which little evolutionary change occurs - and that speciation can occur rapidly over a very short period of time.






42. Controls sensory and motor responses - and controls memory - speech - and intelligence factors.






43. Internally generated patterns of body functions - including hormonal signals - sleep - blood pressure - and temperature regulation - which have approximately a 24-hour cycle and occur even in the absence of normal cues about whether it is day or nigh






44. When the water concentration inside and outside the cell is equal - It is said to be in an...






45. Subsets below the kingdom level






46. 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.






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






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






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






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