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






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






3. Produces gonatotropin releasing hormone (GnRH)






4. A cooperative view of the community that stresses interactions between different species






5. A form of a gene






6. Release of the egg






7. Reproductive successfulness






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






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






10. Going through protein channels with the concentration gradient






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






12. Where cell aerobic respiration takes place






13. Connects the baby to the placenta






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






15. Takes less energy and is more efficient than sexual reproduction






16. A group of populations of different species that live and interact in the same place at the same time






17. Fossil record






18. Unzips the DNA strand






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






20. Both dominant or recessive






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






22. A macromolecule composed of amino acids






23. A molecular unit that consists of a five carbon sugar & one or more phosphate groups & and a nitrogenous base






24. A gene carried on the Y chromosome






25. Going through protein channels with the concentration gradient






26. The study of heredity






27. The production of gametes






28. One dominant and one recessive






29. How the molecule folds on itself due to the functional group interactions






30. A stack of thylakoids






31. Any environmental factor that affects the size of a population but isn't influences by changes in population density & usually abiotic factors






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






33. A common type of gene interaction in which the presence of certain alleles can prevent or mask the expression of a different allele and express their own phenotype instead






34. When DNA replicates






35. Rod shaped prokaryotic cells






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






37. Lays eggs






38. Separates sperm from the egg






39. Reproductive isolation due to different mating times






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






41. Used for long term energy storage & cell membranes & padding and insulation & and steroids & soluble in nonpolar solvents and relatively insoluble in water






42. Holds the cell in place and gives it structure






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






44. Reproductive isolation due to structural differences






45. A single ringed nitrogenous base






46. Both extremes are better than average






47. Choosing certain trains and breeding only individuals that axhibited the desired traits






48. Where protein synthesis takes place






49. The potential ecological niche of a species






50. Where ribosomes are made & in the nucleus
