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. When all the water is sucked out of a cell






2. Grow and divide asexual reproduction






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






4. When natural selection favors individuals of each species that avoid or reduce among coexisting species as a result of each species' niche differing from the others in one or more ways & reducing competition






5. Where sperm is stored






6. Reproductive isolation due to molecular and chemical differences






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






8. Moving into unoccupied niches & causes speciation






9. A group of the populations of all the different species in an area






10. One extreme is bad and the other is good






11. Have trains that maximize the chance of surviving in an environment where the number of individuals is the carrying capacity & have few offspring & are larger & have long life spans & develop slowly & reproduce late & have low reproductive rates & pr






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






13. Aka temperate deciduous forest & broadleaf trees






14. Makes up the cytoskeleton






15. A simple signal that triggers a specific behavioral response






16. Lays eggs






17. Lays down an RNA primer that allows the DNA polymerase to attach to the DNA strand






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






19. A link formed when three or more amino acids combine






20. Microsporocyte after meiosis






21. Oscillation between two things that affect the population & keeps the population in check






22. Occurs when the environment is worsening from too many people






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






24. The enzyme that links the Okazaki fragments






25. Produces eggs






26. Where seminiferous tubules are found & where testosterone is made






27. Occurs when there is the same concentration in different areas






28. Immature sperm cell






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






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






31. When a cell or nucleus has only a single set of chromosomes






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






33. Megasporocyte after meiosis






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






35. Fossil record






36. A mating system in which a male mates with only one female during a breeding season






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






38. Lays eggs






39. Active at nigh






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






41. Cells don't produce new cytoplasm to make the cell bigger & they produce an excess of protons which soften the cell walls so that the water vacuole fills up and makes the cell bigger






42. 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






43. Different traits are passed on separately and independently from one another






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






45. Involves persistent changes in behavior that result from experience






46. Local variation in climate produced by differences in elecation






47. The divergence of two similar species living in the same geographic area






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






49. Plastic cover of the penis






50. Stimulates the interstitial cells to secrete testosterone in males & stimulates ovulation and the development of the corpus luteum in females
