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






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






3. The flow of a charge.






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






5. 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.






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






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






8. A place whjere frsh water and seawater mix.






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






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






11. Plants that die after one growing season.






12. The loutermost layer of the earth.






13. An instrument that measures cloud height.






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






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






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






17. Different versions of a gene in a population.






18. A muscle that pumps to circulate the blood.






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






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






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






22. A protein that aids biochemical reactions.






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






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






25. Study and interpretation of fossils.






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






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






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. The rate of change of an objects velocity.






30. The portion of the Earth from beneath the mantle to the Earth's center.






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






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






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






34. 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.






35. A hormone needed to transpost glucose to cells.






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






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






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






39. Warming of Pacific Ocean seawater along the coast of South America that leads to significant weather changes in the United States.






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






41. The tissues aquatic animals use to breath in water.






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






43. 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.






44. A rod - shaped bacteria.






45. A disease related to lower levels of insulin.






46. An identical copy of an organism.






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






48. An instrument that uses air pressure to record height - such as the height of a plane.






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






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