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 membrane-bound organelles that contain digestive enzymes that digest dead or unused material within the cell or materials absorbed by the cell for use.






2. Engages in both passive and active transport.






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






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






5. Some patrol the blood for antigens - but are also equipped to destroy antigens. They may regulate immune responses as well.

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






8. An enzyme is unaffected by the reactions it catalyzes






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






10. 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.






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






12. Carbon - nitrogen - phosphorous - and water. These are all recycled through biogeochemical processes.






13. Consists of undifferentiated cells capable of quick growth and specialization. It is responsible for elongation of the stem.






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






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






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






17. The class composed of birds.






18. 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






19. 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






20. Is a compound fruit that forms from several ovaries of separate flowers that fuse together during ripening (strawberry - or pineapple).






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






22. Is the major component of sand and is the most abundant element found in the lithosphere. It is not recycled.






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






24. A cell will only remain stable if the surface area of the plasma membrane maintains a __________ with the volume of the cytoplasm.






25. Is a kingdom that includes algae and protozoa.






26. Cleave strands of DNA segments at certain sites.






27. 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.






28. Controls hunger and thirst






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






30. Has loosely packed cells that allow for gas and moisture exchange.






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






32. What phylum are snakes in?






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






34. All store energy within their chemical bonds.






35. An opportunistic life strategy strategy. Lichens invading a bare rock area after a volcanic eruption is an example.






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






37. Are the organelles where cellular respiration occurs.






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






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






40. Controls olfactory lobes (smell)






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






42. Controls balance and muscle coordination






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






44. In DNA Guanine pairs with...






45. 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).






46. Attaches to an enzyme and blocks the enzyme reaction rather than enhancing it - like a prosthetic group would.






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






48. Is the outermost of the three main layers of an embryo.






49. The phyla of round worms.






50. Developed by the German scientists Schleiden and Schwann - States that all living things are made of cells - cells are the basic units of life - all cells come from pre-existing cells.
