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 average per capita birth rate






2. The production of gametes






3. A main component of cell walls of fungi and of the external skeletons of insects & crayfish & and other arthropods






4. Camouflage






5. The constricted region in a chromatid






6. Cold & dry & permafrost & treeless & short growing season






7. A single strand of RNA that carries the information for making a protein






8. The offspring of two genetically dissimilar parents






9. A plant structural compound






10. Fluid filled sac where the primary oocyte divides to form the secondary oocyte and the polar body






11. Any event in time that disrupts community or population structure






12. Promotes cell eleongation & cell division & and seed growth






13. Can make its own food






14. Changes within a species that occur in relatively short periods of time that are the result of changes in the genetic composition of populations






15. The ability of a community to withstand disturbances






16. Reproductive isolation due to different mating signals






17. Produces proteins






18. The change in species composition produced at ecotones






19. 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






20. Light sensitive chemical






21. Aka contest competition & certain dominant individuals get a good supply of the limited resources while the other less dominant organisms in the population don't






22. Microsporocyte after meiosis






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






24. The sequence of nucleotides in one chain dictates the complementary sequence of nucleotides in the other






25. 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






26. Spacing






27. An abrupt decline from high to low population density






28. Can't make its own food






29. One extreme is bad and the other is good






30. Moving molecules into a cell






31. Connects the ovary to the uterus & where fertilization usually takes place






32. Partner chromosomes similar in size & shape & and the position of their centromeres (XX)






33. Makes up the cytoskeleton






34. The process of community development over time & which involves species in one stage being replaced by other species






35. The average per capita death rate






36. Aka chaparral & mixed scrub community with lower rainfall than in a deciduous forest

41. Takes less energy and is more efficient than sexual reproduction






42. Up or down






43. The sequence of amino acids in a protein which are joined by peptide bonds






44. The amount of energy that remains in plant tissues after cellular respiration & the amount of biomass found in excess of that broken down by a plant's cellular respiration for normal daily activities






45. Daily & 24 hour cycles of activity






46. Female part of the flower






47. A single strand of RNA that folds back on itself to form a specific shape






48. The global movement of water between the abiotic environment and organisms






49. The role of an organism within the structure and function of a community & takes into account all biotic and abiotic aspects of the species & as well as all the physical & chemical & and biological factors that it needs to survive & its habitat & wha






50. An arm of an amoeba
