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. Evidence of past life.






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






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






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






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






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






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






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






9. A solute the denotes protons.






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






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






12. A hormone needed to transpost glucose to cells.






13. A cancer treatment that includes chemicals toxic to mailgnant cells.






14. The loutermost layer of the earth.






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






16. An organellein a cell that contains chromosomes.






17. The process in which a diploid cell divides to form haploid cells.






18. Strong upper wind currents in a narrow stream that flow west to east in the United States. Weather patterns are related to the position of the jet stream - which changes often.






19. A muscle that pumps to circulate the blood.






20. Study and interpretation of fossils.






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






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






23. An kinterstellar cloud of dust and gas.






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






25. Reproduction involving only one parent.






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






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






28. A rod - shaped bacteria.






29. 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.






30. The flow of a charge.






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






32. 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.






33. Multicellular organisms whose cells contain organelles.






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






35. A warm - dry wind on the eastern side of the Rocky Mountains.






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






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






38. An almond shaped cloud usually seen on windy days.






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






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






41. 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.






42. 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.






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. Movement of pollen to a plant egg cell - often b y wind - bees - or other animals.






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






46. The process by which seeds develop into seedlings.






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






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






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






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