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. What phylum are snakes in?






2. An orienting response to light.






3. Is a packet of digestive enzymes that destroy cellular wastes.






4. In DNA Guanine pairs with...






5. Includes all living and nonliving components of the Earth to support living things.






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






7. The transfer of electrons.






8. Mass extinctions promote diversification because _______________ - making conditions favorable for the establishment of new - diverse species.






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






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






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






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






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






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






15. Contains multicellular photosynthetic eukaryotic organisms including gymnosperms and angiosperms.






16. Decomposition of living matter for consumption.






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






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






19. Are where the sugars synthesized by photosynthesis travel through to various parts of the plant.






20. 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.






21. Covalent bonds






22. In DNA Thymine pairs with...






23. The sharp boundary of an ecosystem.






24. Is the waxy protective outer coating of leaves.






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






26. Are the organelles where cellular respiration occurs.






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






28. All store energy within their chemical bonds.






29. 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






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






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






32. Cleave strands of DNA segments at certain sites.






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






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






35. Synthesis






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






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






38. The physical place where a particular organism lives. It must include all the factors that will support its life and reproduction.






39. The destruction of gametes - (sex cells such as sperm and eggs).






40. Subsets below the kingdom level






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






42. 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).






43. Engages in both passive and active transport.






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






45. Carbon - Hydrogen - Oxygen - and Nitrogen






46. 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).






47. The preservation of the integrity of genetic information from one generation to another.






48. Is found on the stem between nodes.






49. Some enzymes contain a __________ component that is essential to their functions.






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