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






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






3. The process by which seeds develop into seedlings.






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






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






6. A protein that aids biochemical reactions.






7. The network of glands and tissues that secrete hormones.






8. Small proteins that stimulate viral resistance in cells.






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






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






11. Study and interpretation of fossils.






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






13. The part of flowering plants that contains seeds.






14. Compounds that are fats and oils.






15. The larval stage of an aquatic insect.






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






17. Reproduction involving only one parent.






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






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






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






21. 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.






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






23. A substance that can lead to cancer.






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






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






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






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






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






29. An kinterstellar cloud of dust and gas.






30. The loutermost layer of the earth.






31. Movement of pollen to a plant egg cell - often b y wind - bees - or other animals.






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






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






34. 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.






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






36. A muscle that pumps to circulate the blood.






37. The study of what causes motion.






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






39. Different versions of a gene in a population.






40. A hormone needed to transpost glucose to cells.






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






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






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






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






45. 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.






46. In plants - a seed includes the embryo.






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






48. The rate of change of an objects velocity.






49. An organsim that eats meat - which includes animals - fungi - and plants.






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