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






3. 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






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






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






6. 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.






7. 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.






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






9. Controls balance and muscle coordination






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






11. 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.






12. Are more closely related to Homo Sapiens than to other apes - but Homo Sapiens did not evolve from chimpanzees.






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






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






15. 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






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






17. Has extreme hot or cold temperatures - with very low precipitation - sandy or rocky terrain - sparse vegetation (mainly succulents) - small animals - rodents - and reptiles.






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






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






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






21. Approximately 7 - making it neither basic (under 7) nor alkaline (over 7).






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






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






24. Produce adrenaline. This hormone is a well-known constrictor of blood vessels.






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






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






27. The phyla of round worms.






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






29. Is the sugar that lactase acts upon.






30. Is the organelle where cellular reproductive processes occur.






31. The transfer of electrons.






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






33. Contain one celled eukaryotes such as algae and protozoa.






34. Synthesis






35. 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






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






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






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






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






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






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






42. 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.






43. 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






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






45. Digestive enzymes - hydrochloric acid - and gastric juices which aid in digestion. The mucous secreted by the stomach protects the stomach lining from the acids and juices.






46. An orienting response to light.






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






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






49. Some energy is lost as heat and becomes unusable.






50. Super-class of vertebrae including organisms with no jaws.
