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. Is found on the stem between nodes.






2. 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.






3. Subsets below the kingdom level






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






5. 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






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






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






8. Contains the chromosomes and is the site of reproduction through mitosis and meiosis.






9. There was extensive radiation of fish during the Devonian and Silurian periods within the Paleozoic Era.






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






11. 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.






12. Is the organelle where cellular reproductive processes occur.






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






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






15. Is composed of an anterior and posterior lobe. The stalk of the lobe is connected to the hypothalamus. Antidiuretic Hormone (AH) is produced in the hypothalamus and stored in the posterior pituitary. Upon nervous stimulation from the hypothalamus - t






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






17. 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.






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






19. Is a protein - which is a polymer of amino acids. They generally have the suffix -ase- like lactase.






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






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






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






23. Is the waxy protective outer coating of leaves.






24. Are formed when the plasma membrane of a cell encloses a molecule outside the membrane - then releases a membrane bound sack containing the desired molecule into the cytoplasm. This process allows the cell to absorb molecules that are larger in size






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






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






27. Energy transformations that occur as chemicals are broken down or synthesized within the cell.






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






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






30. Disease causing






31. Controls hunger and thirst






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






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






34. 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.






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






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






37. Process in which elements - chemical compounds - and other forms of matter are passed from one organism to another and from one part of the biosphere to another.






38. Cleave strands of DNA segments at certain sites.






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






40. Decomposition of living matter for consumption.






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






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






43. Occurs when an individual from an adjacent population of the same species immigrates and breeds with a member of a previously locally isolated group - resulting in a change in the gene pool.






44. Are the organelles where cellular respiration occurs.






45. Is a kingdom that includes algae and protozoa.






46. 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.






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






48. Is a substance that changes the speed of a reaction without being affected itself.






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






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