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






2. The part of flowering plants that contains seeds.






3. Small proteins that stimulate viral resistance in cells.






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






5. Compounds that are fats and oils.






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






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






8. An instrument to measure wind speed.






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






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






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






12. The study of what causes motion.






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






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






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






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






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






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






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






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






21. 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.






22. A protein that aids biochemical reactions.






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






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






25. The rate of change of an objects velocity.






26. The process by which seeds develop into seedlings.






27. The flow of a charge.






28. 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.






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






30. The process by which gas reverts back to liquid phase.






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






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






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






34. An instrument that measures cloud height.






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






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






37. The larval stage of an aquatic insect.






38. The green substance that absorbs light during photosynthesis.






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






40. Evidence of past life.






41. A bundle of neurons - or nerve cells.






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






43. 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.






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






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






46. A substance that can lead to cancer.






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






48. An organellein a cell that contains chromosomes.






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






50. Different versions of a gene in a population.
