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 pituitary gland.






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






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






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






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






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






7. In DNA Thymine pairs with...






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






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






10. The phyla composed of segmented worms.






11. In both living and non-living environments.






12. High temperatures






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






14. Contains optic lobes - controls sight.






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






16. Are tubes constructed of a geometrical arrangement of microtubules in a pinwheel shape. Their function includes the formation of new microtubules - but is primarily to form the structural skeleton around which cells split during mitosis and meiosis.






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






18. Anabolism






19. Is found in the root cap and is responsible for quick growth in the roots.






20. Respiratory organs within insects






21. Niche






22. Is found on the stem between nodes.






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






24. Veins in the leaf and are also distributed throughout the stem






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






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






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






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






29. Inorganic phosphate






30. A hydrogen bond involves the ________________ and can be easily broken.






31. 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






32. 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






33. An enzyme is unaffected by the reactions it catalyzes






34. Carbon - Hydrogen - Oxygen - and Nitrogen






35. 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).






36. Super-class of vertebrae including organisms with jaws.






37. The individual we recognize as an adult fern.






38. 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.






39. Covalent bonds






40. Most chemical pollutants accidentally ingested by humans are __________ - mixed with broken down pigments in the bile - then bile is secreted into the small intestine - proceeds to the large intestine - and is expelled in the feces.






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






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






44. Is an accidental change of the DNA sequence of the gene that can result in creating a change of trait that is not found in the parent.






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






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






47. Controls hunger and thirst






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






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






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