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






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






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






4. Study and interpretation of fossils.






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






6. A bundle of neurons - or nerve cells.






7. A muscle that pumps to circulate the blood.






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






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






10. Multicellular organisms whose cells contain organelles.






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






12. An instrument that measures cloud height.






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






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






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






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






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






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






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






20. When the sun is highest in the sky and directly above the Tropic of Cancer 23 1/2 degrees North Latitude. This date usually falls on June 22.






21. This primary component of chromosomes carries an organisms genetic code.






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






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






24. The tissue in plants that conducts nutrients.






25. Different versions of a gene in a population.






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






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






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






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






30. An instrument to measure wind speed.






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






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






33. A substance that can lead to cancer.






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






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






37. The study of the patterns and mechanisms of the transmission of inherited traits from one generation to another.

41. A system comprised of the brain and spinal cord in vertebrates that process and store information.






42. A disease related to lower levels of insulin.






43. 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.






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






45. 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.






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






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






48. A hormone needed to transpost glucose to cells.






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






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