CSET Science Vocab 2

Subjects : cset, science
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.

2. This primary component of chromosomes carries an organisms genetic code.






3. A cancer treatment that includes chemicals toxic to mailgnant cells.






4. The part of flowering plants that contains seeds.






5. Light emission from the upper atmosphere that appear in many shapes and colors.

7. An identical copy of an organism.






8. The study of the patterns and mechanisms of the transmission of inherited traits from one generation to another.






9. The movement of plates and the interaction across the Earth's surface to form land masses.






10. Biological molecules that have important roles in energy metabolism and storage as well as the structure of cells and organisms.






11. Cell division consisting of prophase - metaphase - anaphase - and telophase - that usually creats in two new nuclei - each with a full set of chromosomes.






12. An organism that relies primarily on plants for food.






13. An excess or deficiency of electrons in a body.






14. A way to date organic substances based on the carbon -14 remaining.






15. A visible group of water or ice particles in the atmosphere.






16. The stage of cellular divisions that develops from a zygote.






17. A dark cloud - but not a thundercloud - the frequently produces rain.






18. A cell with one set of chromosomes - which is half the regular (diploid) number.






19. Small proteins that stimulate viral resistance in cells.






20. The place on the surface of the Earth immediately above the 'focus' of an earthquake.






21. The digestive tract between the stomach and anus where most nutrients are absorbed.

31. The reproductive mechanism of prokaryotes.






32. Reproduction involving only one parent.






33. A process through which organisms make nutrients available to cells.

36. The process by which gas reverts back to liquid phase.






37. The flow of a charge.






38. An almond shaped cloud usually seen on windy days.






39. A dry - north wind in late spring - summer - and early fall in north and central California.






40. An organism's unique place in the environment.






41. A relationship between organisms in which one organism benefits and the other does not die - even though the second organism may be harmed.






42. A preliminary proposition that can be tested through scientific study.






43. The phenomenon when refraction of light makes objects appear where they are not.






44. Calender days when the day and night are the same length.






45. A temperature scale in which water freezes at 0 degrees and boils at 100 degrees.






46. A protein that aids biochemical reactions.






47. Study and interpretation of fossils.






48. In the mateamorphosis of insects - the larva becomes a pupa before it becomes an adult.






49. Atoms of the same chemical element with a different number of neurons but the same number of protons. Isotopes of an element have the same atomic number but may not have the same mass.






50. The rate of change of an objects velocity.
