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






2. Occurs when an individual learns not to respond to a particular stimulus - for instance when a stimulus is repeated many times without consequence.






3. The transfer of electrons.






4. Subsets below the kingdom level






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






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






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






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






9. States that where random mating is occurring within a population that is in equilibrium with its environment - the gene frequencies and genotype ratios will remain constant from generation to generation. It is a mathematical formula that shows why re






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






11. Anabolism






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






13. Stood upright before there was an increase in brain size.






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






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






16. 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






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






18. Sex-linked recessive disorder carried on the x chromosome defined by the absence of one or more proteins required for blood clotting






19. Secretes insulin to lower blood sugar and maintain equilibrium. A person eats three candy bars. Within minutes this endocrine gland affects blood-glucose homeostasis.






20. What phylum are snakes in?






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






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






23. In both living and non-living environments.






24. Controls hunger and thirst






25. Cleave strands of DNA segments at certain sites.






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






27. The large brain and upright posture of Homo Sapiens...






28. Is a coenzyme required in the synthesis of collagen.






29. The phyla of sponges.






30. Is a behavior that is learned during a critical point (often very early) in an individual's life. Imprinting enables the young the recognize members of their own species.






31. Niche






32. 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.






33. Produce seeds without flowers. They include conifers (cone-bearers) and cycads.






34. Transfers water and does not require sieve plates to allow nutrients through.






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






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






37. The sharp boundary of an ecosystem.






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






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






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






41. Respiratory organs within insects






42. An orienting response to light.






43. 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.






44. 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.






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






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






47. Is the period when the cell is active in carrying on the function it was designed to perform within the organism. Cells spend much more time in interphase than in cell division.






48. 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.






49. An enzyme is unaffected by the reactions it catalyzes






50. Develops from the morula as a thin layer of cells surrounding an internal cavity.
