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






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






3. The proportion of a specific allele in a particular population






4. The cycle that goes from oen organism to another in food chains and from living organisms to the abiotic environment and back






5. A form of a gene






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






7. Found out that the hormone was being produced in the tip






8. All the alleles present in the population






9. A species that affects the community because it is very common






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






11. An arm of an amoeba






12. An arm of an amoeba






13. Emphasizes species individuality & shows how each species has its own abiotic living requirements






14. When the heterozygote has a phenotype intermediate between those of its two parents






15. The layer that surrounds the cell and holds everything in






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






17. The change in allelic frequencies of two or more populations over time & the interdependent evolution of two or more interacting species






18. Gives live birth






19. The change in species composition over time in a habitat that was not previously inhabited by organisms (no soil)






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






21. When a molecule attaches to the channel and the carrier 'somersaults' to the other side and releases the molecule & then returns to its original side






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






23. Lining of the uterus






24. Changes in the shape of a protein and the accompanying loss of its biological activity






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






26. Contains enzymes that help with fertilization






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






28. All the alleles present in the population






29. The structure in the mitochondria






30. Towards the stimulus






31. The time when no cell division in occurs






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






33. Where cell aerobic respiration takes place






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






35. Both individuals have male and female parts but don't self fertilize






36. The start of a gene






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






38. The study of heredity






39. Aka scramble competition & all the members of the population have a generally equal amount of the resources






40. The passage of energy in a one-way direction through an ecosystem






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






42. An organic compound consisting of only carbon and hydrogen






43. A channel that takes things from one side of the phospholipid bilayer to the other by having a protein attach to the channel which changes its shape and moves the stuff to the other side






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






45. Holds the cell in place and gives it structure






46. A form of active transport that uses energy to pump ions from the outside to the inside of a cell






47. Stores water in plants






48. Chromosomes other than sex chromosomes






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






50. Active at nigh
