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 organism that relies primarily on plants for food.






2. The rate of change of an objects velocity.






3. The process by which gas changes directly to the solid phase.






4. A muscle that pumps to circulate the blood.






5. A bundle of neurons - or nerve cells.






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






7. A cell with one set of chromosomes - which is half the regular (diploid) number.






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






9. Evidence of past life.






10. A solute that accepts protons.






11. A substance that can lead to cancer.






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






13. 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.






14. In plants - a seed includes the embryo.






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






16. An kinterstellar cloud of dust and gas.






17. Calender days when the day and night are the same length.






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






19. A simple sugar and a product of photosynethesis.






20. The study of what causes motion.






21. Material deposited by a glacier and often marking a glacier's furthest advance.






22. A tissue in the uterus through which nutrients pass from the mother to the fetus.






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






24. A solute the denotes protons.






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






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






27. A protein that aids biochemical reactions.






28. 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.






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






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






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






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






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






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






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

37. An identical copy of an organism.






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






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






40. 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.






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






42. 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.






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






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






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






46. The process by which seeds develop into seedlings.






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






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






49. An instrument that measures cloud height.






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