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. Takes less energy and is more efficient than sexual reproduction






2. Birth canal






3. Aka boreal forest & big evergreen forests & cold most of the year






4. Compounds with the same molecular formulas but different structures






5. The assignments of codons for amino acids and for start and stop signals






6. Going through protein channels with the concentration gradient






7. The tubules that extend from each pole to the equatorial region






8. A compound present on the outer surface of cells that aren't bacteria






9. An individual of unknown genotype is crossed with a homozygous recessive individual






10. The measure of the relative importance of each species within a community & based on its abundance & productivity & or size






11. 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






12. Where cells are actively dividing






13. The stuff in between the granum






14. 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






15. The pressure necessary to keep the water from moving in a you-tube






16. Light sensitive chemical






17. Abstinence during ovulation period






18. A geographic area that animals seldom leave






19. The process by which heritable traits make it more likely that an organism will have greater reproductive success






20. Produces semen (1)






21. One species excludes another from its niche as a result of interspecific competition






22. The concentration is equal in both areas






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






24. Little 'hairs' around the membrane used for movement






25. The study of how living organisms and the physical environment interact in an immense and complcated web of relationships & the broadest field of biology






26. Where cell aerobic respiration takes place






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






28. Gases act like a blanket and hold heat in the atmosphere






29. A group of atoms that determines the types of chemical reactions and associations in which the compound participates






30. Aka temperate deciduous forest & broadleaf trees






31. Both extremes are better than average






32. The number of species in a community






33. The end of a lineage






34. Makes up the cytoskeleton






35. Unfertilized egg develops into a reproducing haploid animal that is capable of reproducing using a different process to make gametes






36. Energy level






37. The person that said that the human population would quickly outgrow the natural resources and that it would cause war






38. 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






39. On the side where the 3' carbon is


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. Chemical messenger






42. The genetic drift that results when a small number of individuals from a large population found a new colony






43. A link formed when two amino acids combine






44. A form of natural selection that increases inclusive fitness through the breeding success of close relatives






45. A section of three nitrogenous bases






46. The process by which heritable traits make it more likely that an organism will have greater reproductive success






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






48. A symbiotic relationship in which the parasite benefits which the host is harmed






49. A graph that illustrates the total biomass at each successive trophic level






50. When there is equilibrium between to areas & but molecules are still moving
