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






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






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






4. 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






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






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






7. Can be accounted for by the theory of punctuated equilibrium. The fossil record shows periods of stability with regard to appearance and disappearance of species as well as periods of sudden change.






8. Disease causing






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






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






11. Becomes available for erosion as undersea sedimentary rocks are up-thrust by volcanic activity - erosion releases it from rocks into streams where it combines with oxygen to form phosphates in lakes that are then absorbed by plants - it is recycled t






12. High temperatures






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






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






15. Synthesis






16. 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).






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






18. The phyla composed of segmented worms.






19. Secretes insulin to lower blood sugar and maintain equilibrium. A person eats three candy bars. Within minutes this endocrine gland affects blood-glucose homeostasis.






20. Cleave strands of DNA segments at certain sites.






21. Is a kingdom that includes algae and protozoa.






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






23. Breaking down






24. Has extreme cold temperatures - low precipitation - modified grassland - perma-frost - a short growing season and some plants and animals.






25. Are the monomers that form nucleic acids - containing a sugar - phosphate group - and a nitrogenous base.






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






27. Mitochondria - they constitute the center of cellular respiration.

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






29. Develops from the morula as a thin layer of cells surrounding an internal cavity.






30. Are formed when the plasma membrane of a cell encloses a molecule outside the membrane - then releases a membrane bound sack containing the desired molecule into the cytoplasm. This process allows the cell to absorb molecules that are larger in size






31. Is the organelle where cellular reproductive processes occur.






32. Small - green - heart-shaped gametophyte plant form of a fern that can make its own food and absorb water and nutrients from the soil






33. 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






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






35. 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.






36. The preservation of the integrity of genetic information from one generation to another.






37. 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.






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






39. Energy transformations that occur as chemicals are broken down or synthesized within the cell.






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






41. The phylum of insects (bees).






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






43. Decomposition of living matter for consumption.






44. Is the waxy protective outer coating of leaves.






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






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






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






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






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






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