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.
1. The movement and collision of gas molecules in the atmosphere that can form into high or low pressure areas.






2. 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.






3. Small proteins that stimulate viral resistance in cells.






4. Rings that show how many years a tree has been growing. The thickness of the rings may reveal other information about climatic conditions.






5. The process by which seeds develop into seedlings.






6. A tissue in the uterus through which nutrients pass from the mother to the fetus.






7. A cell with two copies of each chromosome.






8. Fluid that circulates throughout the body of an animal - distributing nutrients - and usually oxygen.






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






10. Molten rock flormed in the Earth that may appear on the surface.






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






12. The study of the interactions of organisms with their environment and with each other.






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






14. A system for transporting nutrients and other essential materials throughout the body.






15. A hormone needed to transpost glucose to cells.






16. A bundle of neurons - or nerve cells.






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






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






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






20. An instrument that measures cloud height.






21. Light refracted through raindrops to form colors of a spectrum from red to blue.






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






23. The reproductive parts of flowering plants.






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






25. 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.






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






27. A place whjere frsh water and seawater mix.






28. A mammal whose young crawl into it's mothers pouch to complete development.






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






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






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






32. An organellein a cell that contains chromosomes.






33. Reproduction involving only one parent.






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






35. The Earth's atmosphere is primarily nitrogen and oxygen. The troposphere extends from the surface to about 10 km.; the stratosphere from 10km to 50 km.; the mesosphere from 50 km. to 80 km.; and the thermosphere is the atmosphere beyond 80 km.






36. Evidence of past life.






37. The reproductive mechanism of prokaryotes.






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






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






40. The physical - chemical - and biological processes by which rock is broken down into smaller pieces.






41. In most Amphibians - a process in which larve goes through significant changes - perhaps including a pupa stage - before becoming an adult.






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






43. The larval stage of an aquatic insect.






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






45. A single DNA molecule - a tightly coiled strand of DNA - condensed into a compact structure.






46. The loutermost layer of the earth.






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






48. Different versions of a gene in a population.






49. The process by which gas changes directly to the solid phase.






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