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. Multicellular organisms whose cells contain organelles.






2. The reproductive mechanism of prokaryotes.






3. Soil beneath the earth's surface that stays frozen throughout the year.






4. The process by which seeds develop into seedlings.






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






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






7. An organellein a cell that contains chromosomes.






8. The combined cooling effect of wind and temperature. Higher wind chills indicate that a body will cool more quickly to the air temperature.






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






10. A loud nise caused by a shock wave when an object exceeds the speed of sound.






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






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






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






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






15. A relationship between disimilar organisms that is adventageous to one and doesn't affect the other.






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






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






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






19. A disease related to lower levels of insulin.






20. 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.






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






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






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






24. Study and interpretation of fossils.






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






26. The part of flowering plants that contains seeds.






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






28. A hormone needed to transpost glucose to cells.






29. 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.






30. The green substance that absorbs light during photosynthesis.






31. A cell with two copies of each chromosome.






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






33. The part of the gut that connects the pharynx and stomach.






34. A place whjere frsh water and seawater mix.






35. The rate of change of an objects velocity.






36. In plants - a seed includes the embryo.






37. A rod - shaped bacteria.






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






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






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






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






42. An instrument that measures cloud height.






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






44. A solute that accepts protons.






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






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






47. A layer of tree bramches and other vegetation elevated above ground.






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






49. One nautical mile per hour or about 1.15 miles per hour.






50. When the sun is directly over the equator. This date usually occurs on March 20.
