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






2. Any process that leads to new gene combinations






3. Immature sperm cell






4. Moving into unoccupied niches & causes speciation






5. Involves mitosis and cytokinesis






6. Collects waste products in a land egg






7. Fertile soil & all grass






8. The arrival of the chromosomes at the poles and cytokinesis






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






10. Species interacting in a positive way & Which modifies and enhances the local environment for other species






11. The constricted region in a chromatid






12. Warning coloration & conspicuous colors of patters which advertise a species' unpalatibility to potential predators






13. One dominant and one recessive






14. Male gamete released into the female






15. The global movement of phosphorus between the abiotic environment and organisms






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






17. Required for making a boy a boy and sexual growth






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






19. Speciation that occurs when one population becomes geographically separated from the rest of the species and subsequently evolves by natural selection/genetic drift






20. The number of individuals of a species per unit of area or volume at a given time






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






22. Reproductive isolation due to different mating times






23. Aka temperate deciduous forest & broadleaf trees






24. Eggs laid and then fertilized






25. Going from areas of low to high concentration & goes against the concentration gradient & requires cell energy






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






27. The ability to produce viable offspring






28. The concentration is equal in both areas






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

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






33. Stalk of the stamen






34. Aka temperate deciduous forest & broadleaf trees






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






36. Inhibits ovulation & affects the endometrium and cervical mucus to prevent implantation & regulates the menstrual cycle






37. Has its own life support for the embryo






38. Provides genetic variation through recombination






39. Contains two monosaccharide rings joined by a ether link






40. The graph of the number of surviving individuals against age (birth to maximum age)






41. Same organism makes both gametes & no genetic recombination






42. Growth response to physical disturbance & positive or negative






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






44. Same organism makes both gametes & no genetic recombination






45. All the alleles present in the population






46. A combination of natural selection and genetics






47. Used for reproductive purposes and peeing






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






49. Covalently linking monomers






50. Holds the cell in place and gives it structure
