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. 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.






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






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






4. Protein synthesis






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






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






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






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






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






10. The phyla composed of segmented worms.






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






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






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






14. Is weaker than ionic - covalent - disulfide - or double bonds.






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






16. 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.






17. 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.






18. The pituitary gland.






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






20. The most recent and present era. It includes the radiation of flowering plants - the angiosperms.






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






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






23. 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.






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






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






27. In DNA Thymine pairs with...






28. 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.






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






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






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






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






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






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






35. Controls hunger and thirst






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






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






38. Covers and protects the leaf.






39. Is a kingdom that includes algae and protozoa.






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






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






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






43. Is found on the stem between nodes.






44. The process of forming eggs and sperm cells in the reproductive organs.






45. 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






46. Is the waxy protective outer coating of leaves.






47. 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.






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






49. 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.






50. The pharynx is between the nasal passage and the trachea. Air passes into the body via the nasal passage - then passes through the pharynx and on to the trachea.
