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 tissue in plants that conducts nutrients.






2. In the United States - the part of the western mountains that seperates water flowing toward opposite sides of the country.






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






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






5. Small proteins that stimulate viral resistance in cells.






6. A ridge built in water by organisms such as coral.






7. An instrument to measure wind speed.






8. 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.






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






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






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






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






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






14. A disease related to lower levels of insulin.






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






16. The study of what causes motion.






17. An organellein a cell that contains chromosomes.






18. Plants that die after one growing season.






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






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






21. A malignant tumor - which forms in the skin and outside of internal organs.






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






23. The green substance that absorbs light during photosynthesis.






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






25. A bundle of neurons - or nerve cells.






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






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






28. A cell that reacts to stimuli and transmits impulses consisting of a body with a nucleus and dendrites to receive and axons to transmit impulses.






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






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






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






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






33. Study and interpretation of fossils.






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






35. A rod - shaped bacteria.






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






37. 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.






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






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






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






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






42. The larval stage of an aquatic insect.






43. The loutermost layer of the earth.






44. Compounds that are fats and oils.






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






46. In plants - a seed includes the embryo.






47. A substance that can lead to cancer.






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






49. An identical copy of an organism.






50. Strong upper wind currents in a narrow stream that flow west to east in the United States. Weather patterns are related to the position of the jet stream - which changes often.
