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






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






3. 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.






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






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






6. The flow of a charge.






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






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






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






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






11. The reproductive parts of flowering plants.






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






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






14. The rate of change of an objects velocity.






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






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






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






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






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






20. Different versions of a gene in a population.






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






22. Reproduction involving only one parent.






23. 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.






24. A place whjere frsh water and seawater mix.






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






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






27. 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.






28. In the United States - the part of the western mountains that seperates water flowing toward opposite sides of the country.






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






30. The green substance that absorbs light during photosynthesis.






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






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






33. 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.






34. Plants that die after one growing season.






35. A dry - north wind in late spring - summer - and early fall in north and central California.






36. The process by which seeds develop into seedlings.






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






38. A protein that aids biochemical reactions.






39. Multicellular organisms whose cells contain organelles.






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






41. An instrument to measure wind speed.






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






43. The loutermost layer of the earth.






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






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






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






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






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






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






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