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






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

13. The phyla of sponges.






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






15. An orienting response to light.






16. Occurs when an individual learns not to respond to a particular stimulus - for instance when a stimulus is repeated many times without consequence.

20. A suffix meaning 'to break apart.' O || ||






21. Provide rigidity to plant cells (and some bacteria) and are not found within animal cells.






22. In order to become an established part of an island ecosystem there must be a populations large enough to ensure _________ - a food source - a suitable habitat - and a source of moisture.






23. 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.






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






25. Breaking down






26. 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.

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






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






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






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






32. Synthesis

46. 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.






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






48. Subsets below the kingdom level






49. Super-class of vertebrae including organisms with no jaws.






50. Is the period when the cell is active in carrying on the function it was designed to perform within the organism. Cells spend much more time in interphase than in cell division.
