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. Gives live birth






2. The cells that don't become eggs in oogenesis






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






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






5. A system of tubes and tubules used for internal storage and transport of proteins






6. When all the water is sucked out of a cell






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






8. Participates in the process in which amino acids are linked to form polypeptides






9. Reproductive isolation due to molecular and chemical differences






10. Promotes cell elongation & apical dominance






11. An actively cooperating group of individuals belonging to the same species and often closely related






12. A gateway in the cell membrane that lets molecules through






13. Species that show repetitive reproductive cycles






14. Flowering plant






15. Lays eggs






16. When individuals are evenly spaced & occurs because of territoriality or competition for resources or space






17. An environmental factor whose ways of affecting a population are altered when there is a change in population density






18. A nucleic acid polymer consisting of nucleotide subunits that can associate by complementary base paining with the single-strand DNA template






19. Warm & lots of rain & highest level of diversity and production






20. A tool of ecological management in which the undergrowth and plant litter are deliberately burned under controlled condition before they accumulate to dangerous levels






21. The largest population that can be maintained for an indefinite period by a particular environment as long as there are no changes in it






22. The empty space in the ER tubes






23. Provides food for the developing embryo in a land egg






24. Holds the ovules






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






26. A periodic long-distance travel from one location to another






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






28. Shows interactions at their most basic level (who eats who)






29. Release of the egg






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






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






32. Reproductive successfulness






33. The complex formed when the enzyme and substrate combine






34. Light sensitive chemical






35. Towards the stimulus






36. A graph of the number of organisms at each trophic level in a given ecosystem






37. Lateral






38. The lifestyle a species actually pursues and the resources it actually uses






39. A simple signal that triggers a specific behavioral response






40. 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






41. The strand of DNA that is always growing away from the replication fork & so only short pieces can be synthesized






42. All the alleles present in the population






43. Reproductive isolation due to different mating times






44. The global movement of carbon between the abiotic environment and organisms






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






46. Local variation in climate produced by differences in elecation






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






48. When most are average and extremes are better






49. An environmental factor whose ways of affecting a population are altered when there is a change in population density






50. When one individual behaves in a way that seem to benefit others rather than itself
