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. Cells are the basic unit of living organisms and all cells come from pre-existing cells






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






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






4. Reads bases and puts the correct base into it & can only lay down in one direction






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






6. Where ribosomes are made & in the nucleus






7. The sequence of nucleotides in one chain dictates the complementary sequence of nucleotides in the other






8. Plastic cover of the penis






9. 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






10. 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






11. A lipid that consists of a clycerol molecule attached at one end to two fatty acids & and at the other end to a phosphate group linked to an organic compound






12. A compound in which carbon atoms are covalently bonded to one another to form the backbone of the molecule






13. Eggs and sperm combine






14. An economical form of reserve fuel storage which yields over two times more energy than carbs when metabolized






15. A main component of cell walls of fungi and of the external skeletons of insects & crayfish & and other arthropods






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






17. Moving a liquid molecule into a cell






18. Spiral shaped prokaryotic cells






19. When individuals in a population are spaced throughout an area in a way that is unrelated to where other are & the least common type of dispersion






20. A community with the abiotic factors of the place






21. Aka contest competition & certain dominant individuals get a good supply of the limited resources while the other less dominant organisms in the population don't






22. All of the contents of the cell inside the membrane






23. A section of three nitrogenous bases






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






25. Shows interactions at their most basic level (who eats who)






26. Both extremes are better than average






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






28. Immature sperm cell






29. Cutting of vas deferens






30. When females select their mates on the basis of some physical trait or some resource offered by the winning suitor






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






32. The end of a lineage






33. Promotes cell eleongation & cell division & and seed growth






34. Competition among population of different species






35. Lateral






36. Initial shoot that comes out of the ground






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






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






39. The possession of two or more set of chromosomes






40. Any process that leads to new gene combinations






41. Initial fertilized cell






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






43. Inhibits ovulation & lasts a long time






44. Going through protein channels with the concentration gradient






45. The enzyme that controls the cell cycle & is destroyed during mitosis






46. Makes up the cytoskeleton






47. Produces gonatotropin releasing hormone (GnRH)






48. Morning after pill






49. Destoy the ozone layer






50. The maximum rate at which a population of a given species could increase under ideal conditions & plenty of resources &and a low population density & is influenced by the age of reproductive maturity & how long the organism is able to reproduce & and
