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. Study and interpretation of fossils.






2. The green substance that absorbs light during photosynthesis.






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






4. All the organisms in an area and the environment in which they live.






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






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






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






8. The loutermost layer of the earth.






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






10. Small proteins that stimulate viral resistance in cells.






11. A hormone needed to transpost glucose to cells.






12. A cell with two copies of each chromosome.






13. Reproduction involving only one parent.






14. Plants that die after one growing season.






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






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






17. A substance that can lead to cancer.






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






19. 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.






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






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






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






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






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






25. 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.






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






27. Long term patterns of temperature - humidity and amount of sunshine.






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






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






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






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






32. The fundamental unit of all life. The cell consists of an outer plasma membrane - the cytoplasm - and the genetic material (DNA).






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






34. Different versions of a gene in a population.






35. The larval stage of an aquatic insect.






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






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






38. A protein that aids biochemical reactions.






39. A bundle of neurons - or nerve cells.






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






41. An instrument to measure wind speed.






42. A place whjere frsh water and seawater mix.






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






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






45. The study of what causes motion.






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






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






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






49. An kinterstellar cloud of dust and gas.






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