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.
1. The graph of the comparison of trophic levels by determining the number of organisms & the biomass & or the relative energy found at each level






2. A fatty acid that doesn't contain the maximum possible number of hydrogens






3. Where cell aerobic respiration takes place






4. Quantitative estimate of the total mass & the amount of living material






5. States that species richness is greatest at moderate levels of disturbance & so all the different species are at different stages in succession






6. The site of photosynthesis






7. A conservation approach that emphasizes restoring and maintaining the quality of an entire ecoystem rather than the conservation of individual species






8. An organic compound with 3-7 carbons with a hydroxyl (OH) group bonded to each but one & which is double bonded to an oxygen






9. A simple signal that triggers a specific behavioral response






10. The constricted region in a chromatid






11. The transmission of genetic information from parent to offspring






12. A compound on the surface of animal cells that allow cells to recognize and interact with one another






13. A geographic area that animals seldom leave






14. Reproductive isolation due to molecular and chemical differences






15. Moving a liquid molecule into a cell






16. Busiest at dawn or dusk






17. Forms the initial seed leaves (not actual leaves) & a side of the seed






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






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






20. Competition among population of different species






21. A lipid that consists of carbon atoms arranged in four attached rings & three of which are hexagonal and the other is pentagonal






22. Cutting of vas deferens






23. The number of individuals of a species per unit of area or volume at a given time






24. Checks for errors and takes of RNA primer






25. Cells are the basic unit of living organisms and all cells come from pre-existing cells






26. Stores water in plants






27. The formation of an association between some normal body function and a new stimulus






28. A behavior that has been modified in response to environmental experience






29. The interaction of two or more animals & usually of the same species






30. A type of social learning based on early experience which allows offspring to bond to their mother






31. Fluid filled chamber that surrounds and protects the developing embryo in a land egg






32. Physically changing from sex when there aren't any of one sex






33. Proposes that simple prokaryotic organisms began living in symbiotic relationships that eventually became obligatory (necessary) as one cell engulfed the other






34. Stable relationships that ensure cooperative behavior in mating and the rearing of the young






35. CAT






36. Growth response to light & positive






37. Moving molecules into a cell






38. A membrane where some things can go through & and others can't






39. Aka aggregated distribution & occurs when resources in an area are clumbed & when there is limited seed dispersal or asexual reproduction & or when families/colonies all live together & good because the organisms can protect one another






40. Forms the initial seed leaves (not actual leaves) & a side of the seed






41. A structure that separates the duplicated chromosomes during anaphase






42. Making more DNA






43. Stimulates the anterior pituitary to make FSH and LH






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






45. Megaspore after mitosis






46. An economical form of reserve fuel storage which yields over two times more energy than carbs when metabolized






47. The movement of alleles






48. Moving a solid molecule into a cell






49. When water moves into a cell and keeps going in until the membrane bursts






50. The study of behavior in natural environments from an evolutionary perspective
