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 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.






2. The rate of change of an objects velocity.






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






4. An identical copy of an organism.






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






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






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






8. That part of the body cavity between the mouth and the anus including in most animals the mouth - the pharynx - esophagus - stomach - intestine - and the anus.






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






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






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






12. Rings that show how many years a tree has been growing. The thickness of the rings may reveal other information about climatic conditions.






13. The study of what causes motion.






14. Reproduction involving only one parent.






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






16. The larval stage of an aquatic insect.






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






18. 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.






19. The process by which seeds develop into seedlings.






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






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






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






23. A solute that accepts protons.






24. Multicellular organisms whose cells contain organelles.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






43. Study and interpretation of fossils.






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






45. The green substance that absorbs light during photosynthesis.






46. Different versions of a gene in a population.






47. A protein that aids biochemical reactions.






48. A rod - shaped bacteria.






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






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