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 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.






2. Is a compound fruit that develops from many ovaries of a single flower fusing together (raspberry).






3. Fruits that develop from a single ripened ovary (apple - olive - acorn - cucumber).






4. Where protein synthesis occurs. They float unattached in the cytoplasm. They contain RNA that is specific to their function in protein formation.






5. In DNA Thymine pairs with...






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






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






8. Proposes that those individuals within a population that are most adapted to the environment are also the most likely individuals to produce viable offspring.






9. Produce adrenaline. This hormone is a well-known constrictor of blood vessels.






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






11. Is the organelle where cellular reproductive processes occur.






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






13. 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.






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






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






16. A type of innate behavior (instinct.) The FAP is a preprogrammed response to a particular stimulus (known as a releaser stimulus). FAP's include courtship behaviors and feeding of young. These are not learned behaviors - they are automatically perfor






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






18. Is the earliest period of the Paleozoic era. Began with the Cambrian explosion - this explosion of life resulted in the representatives of most of the modern phyla being present.






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






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






21. This is a carboxyl group and is the signature group found within organic acids.






22. Are cells involved in immunity and are produced in bone marrow as stem cells.






23. Covalent bonds






24. High temperatures






25. Are the organelles where cellular respiration occurs.






26. Niche






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






28. Is a phylum that contains jellyfish - hydra - etc.






29. Synthesis






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






31. 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.






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






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






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






35. A length of DNA (with corresponding histones) is responsible for the production of a certain protein that causes a particular trait to be expressed in an organism.






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






37. 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.






38. 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.






39. The process whereby cells build molecules and store energy (in the form of covalent chemical bonds).






40. 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.






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






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






43. Produces the most ATP molecules - yielding 34 ATPs per glucose molecule.






44. 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.






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






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






47. Is the waxy protective outer coating of leaves.






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






49. Controls hunger and thirst






50. Is when expression of genetic traits is determined by weather the trait is inherited from the mother or the father.
