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






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






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






4. 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.






5. A solute that accepts protons.






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






7. A protein that aids biochemical reactions.






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






9. A way to date organic substances based on the carbon -14 remaining.






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






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






12. An instrument to measure wind speed.






13. The reproductive mechanism of prokaryotes.






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






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






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






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






18. The flow of a charge.






19. 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.






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






21. 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.






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

25. Plants that die after one growing season.






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






27. 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.






28. The loutermost layer of the earth.






29. A bundle of neurons - or nerve cells.






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

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






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






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






44. Evidence of past life.






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






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






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






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






49. Floating aquatic plants (phytoplankton) and animals (zooplankton).






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