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






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






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






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






5. A bundle of neurons - or nerve cells.






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






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






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






9. A solute the denotes protons.






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






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






12. 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.






13. A place whjere frsh water and seawater mix.






14. An kinterstellar cloud of dust and gas.






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






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






17. The tissue in plants that conducts nutrients.






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






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






20. The process by which seeds develop into seedlings.






21. A protein that aids biochemical reactions.






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






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






24. A substance that can lead to cancer.






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






26. A muscle that pumps to circulate the blood.






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

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






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






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






36. A cell with two copies of each chromosome.






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

43. The larval stage of an aquatic insect.






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






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






46. An organellein a cell that contains chromosomes.






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






48. The study of what causes motion.






49. A rod - shaped bacteria.
