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 kinterstellar cloud of dust and gas.






2. In plants - a seed includes the embryo.






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






4. The movement and collision of gas molecules in the atmosphere that can form into high or low pressure areas.






5. 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.






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






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






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






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






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






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






12. Plants that live through more than one growing season.






13. The flow of a charge.






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






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






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






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






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






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






20. Rings that show how many years a tree has been growing. The thickness of the rings may reveal other information about climatic conditions.






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






22. An identical copy of an organism.






23. Small proteins that stimulate viral resistance in cells.






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






25. Study and interpretation of fossils.






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






27. A bundle of neurons - or nerve cells.






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






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






30. An instrument to measure wind speed.






31. The larval stage of an aquatic insect.






32. 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.






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






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






35. 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.






36. A place whjere frsh water and seawater mix.






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






38. The study of what causes motion.






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






40. Plants that die after one growing season.






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






42. 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.






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






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






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






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






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






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






49. A muscle that pumps to circulate the blood.






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