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.

19. When the animal must do something to gain a reward or to avoid punishment






20. The time between mitosis and the S phase & when the cell grows and performs its function






21. Things that eat the primary consumers & third lowest trophic level






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






23. An evolutionary modification that improves the chances of survival and reproductive success in a given environment






24. A transitional zone where two or more communities meets & contains all or most of the ecological niches of the adjacent communities as well as some that are unique to the ecotone

27. A cooperative view of the community that stresses interactions between different species






28. When individuals in a population are spaced throughout an area in a way that is unrelated to where other are & the least common type of dispersion

43. Spacing






44. The study of heredity






45. The structure in the mitochondria






46. A mutation in which the wrong base it transcribed
