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






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






3. The individual we recognize as an adult fern.






4. Refers to the birthrate of a population.






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






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






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






8. The phylum of insects (bees).






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






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






11. Niche






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






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






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






15. Ended with the extinction of the dinosaurs.






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






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






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






19. Breaking down






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






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






22. 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.






23. The phyla of round worms.






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






25. (of some plants or fungi) feeding on dead or decaying organic matter






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






27. The transfer of electrons.






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






29. Controls olfactory lobes (smell)






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






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






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






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






34. The pituitary gland.






35. An orienting response to light.






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






37. Controls balance and muscle coordination






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






39. 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.






40. Sex-linked recessive disorder carried on the x chromosome defined by the absence of one or more proteins required for blood clotting






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






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






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






44. 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

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






49. 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.






50. Plants and animals obtain usable nitrogen
