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.

5. A term used to describe the coiling strands of DNA molecule that resembles a spiral staircase.






6. Precipitation that evaporates before it reaches the Earth's surface.






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






8. A level of plant and animal classification between class and kingdom.






9. In metamorphosis - the stage between the larva and adult.






10. Material deposited by a glacier and often marking a glacier's furthest advance.






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






12. A group of plants that produce seeds enclosed within an ovary - which mat mature into a fruit.






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






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






15. The network of glands and tissues that secrete hormones.






16. The reproductive mechanism of prokaryotes.






17. The green substance that absorbs light during photosynthesis.






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






19. The larval stage of an aquatic insect.

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






22. The part of flowering plants that contains seeds.






23. A colorless - odorless gas that is important in the Earth's atmospheric greenhouse effect. Frozen CO2 is dry ice.






24. That part of the body cavity between the mouth and the anus including in most animals the mouth - the pharynx - esophagus - stomach - intestine - and the anus.






25. A protein that aids biochemical reactions.






26. A system comprised of the brain and spinal cord in vertebrates that process and store information.

31. The movement up in the atmosphere of heated moisture. Thunderstorms are often caused by convection.






32. Reproductive haploid cells that combine to creat a zygote.






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






34. An identical copy of an organism.






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






36. A temperature scale in which 1 degrees Kelvin equals 1 degree Celsius. 0 degree Kelvin is about -273 degree Celsius. Kelvin is called absolute zero because there is no movement of molecules.

41. A place whjere frsh water and seawater mix.






42. An organsim that eats meat - which includes animals - fungi - and plants.






43. 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.






44. Plants that live through more than one growing season.






45. An instrument that measures cloud height.






46. Movement of pollen to a plant egg cell - often b y wind - bees - or other animals.






47. Floating aquatic plants (phytoplankton) and animals (zooplankton).






48. The process in which a diploid cell divides to form haploid cells.






49. A substance that can lead to cancer.
