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. Decomposition of living matter for consumption.






2. Is disorganized - unravelled - DNA with histones attached.






3. Is a molecule that stores information for protein synthesis and genetic coding.






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






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






6. Is the sugar that lactase acts upon.






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






8. Anabolism






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






10. 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.






11. Is a kind of plain characterized by a warm climate - grassland - and seasonally dry climate conditions.






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






13. An orienting response to light.






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






15. Is a phylum that contains sponges.






16. Is the organelle where cellular reproductive processes occur.






17. Is a social behavior of an organism that is beneficial to the group at the individual's expense.






18. The cells of a developing embryo (at the gastrula stage) differentiate into layers - that will later develop into different tissues and organs - including the mesoderm - ectoderm - and endoderm.






19. Cleave strands of DNA segments at certain sites.






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






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






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






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






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






25. The size of a cell is limited by the ratio of its surface area to volume.






26. What phylum are snakes in?






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






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






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






30. 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

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

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

41. Respiratory organs within insects






42. 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.






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. The class composed of birds.
