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. An instrument to measure wind speed.






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






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






4. `An important class of plant hormones associated with growth patterns.






5. 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.






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






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






8. The framework for the attatchment of skeletal muscles in vertebrates that also protect vital organs.






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






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






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






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






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






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






15. Study and interpretation of fossils.






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






17. The part of Earth located between the crust and the core.






18. Plants that die after one growing season.






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






20. The level of plant and animal between the species and the family.






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






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






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






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






25. 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.






26. Small proteins that stimulate viral resistance in cells.






27. A bundle of neurons - or nerve cells.






28. In plants - a seed includes the embryo.






29. 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.






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






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






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






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






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






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






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






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






38. An kinterstellar cloud of dust and gas.






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






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






41. An identical copy of an organism.






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






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






44. The green substance that absorbs light during photosynthesis.






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






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






47. The reproductive parts of flowering plants.






48. A place whjere frsh water and seawater mix.






49. Fertilization of one plant by pollen from a different plant species.






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