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






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






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






4. A simple sugar and a product of photosynethesis.






5. A disease related to lower levels of insulin.






6. Study and interpretation of fossils.






7. The study of what causes motion.






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






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






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






11. The part of flowering plants that contains seeds.






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






13. An instrument to measure wind speed.






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






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






16. A bundle of neurons - or nerve cells.






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

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. Plants that die after one growing season.






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






24. A mammal whose young crawl into it's mothers pouch to complete development.






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






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






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






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






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






30. A place whjere frsh water and seawater mix.






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






32. 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.






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






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






35. 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.






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






37. The reproductive mechanism of prokaryotes.






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






39. The green substance that absorbs light during photosynthesis.






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






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