Honors Freshman Science

Subject : 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.

22. Where cells are actively dividing






23. Changes that take place over very long periods of time that may result in speciation






24. A disaccharide made from glucose and fructose & table sugar






25. All life forms must come from pre-existing life (correct idea)






26. Used for long term energy storage & cell membranes & padding and insulation & and steroids & soluble in nonpolar solvents and relatively insoluble in water

45. A geographic area that animals seldom leave






46. A species is protected because of its similar appearance to an undesirable species






47. Speciation that occurs when one population becomes geographically separated from the rest of the species and subsequently evolves by natural selection/genetic drift






48. All the Earth's communities and their interactions and connections with the planet's abiotic factors






49. Has cones






50. Any environmental factor that affects the size of a population but isn't influences by changes in population density & usually abiotic factors
