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. Grasses and scattered trees & less precipitation than in grasslands






2. The start of a gene






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






4. The study of how both the number of individuals in a certain species that are found in an area and the dynamics of the population






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






6. 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






7. Reproductive isolation due to different mating times






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






9. The formation of an association between some normal body function and a new stimulus






10. Local variation in climate produced by differences in elecation






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






12. Contain identical & double stranded DNA sequences (><)






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






14. Energy level






15. The ability to adapt past experiences that may involve different stimuli to solve a new problem






16. 'packages' cell products






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






18. The largest population that can be maintained for an indefinite period by a particular environment as long as there are no changes in it






19. The average per capita death rate






20. Collects waste products in a land egg






21. A membrane where some things can go through & and others can't






22. A graph that indicates the energy content of the biomass of each trophic level






23. A tool of ecological management in which the undergrowth and plant litter are deliberately burned under controlled condition before they accumulate to dangerous levels






24. Grow and divide asexual reproduction






25. Produces semen (2)






26. Opening into the uterus






27. The production of gametes






28. Reproductive isolation due to different mating signals






29. A single strand of RNA that folds back on itself to form a specific shape






30. When the chromatin fibers condense into chromosomes






31. A parasite that lives inside the host






32. 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






33. Where protein synthesis takes place






34. Chemical messenger






35. The local environment where a species lives






36. Inhibits ovulation & lasts a long time






37. The ability of a community to withstand disturbances






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






39. A graph that indicates the energy content of the biomass of each trophic level






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






41. The possession of two or more set of chromosomes






42. Occurs when each individual in a population consumes too large a share of resources






43. Eggs formed and held in the mother & eggs hatch and the offspring leaves the mother






44. AAAA...






45. A protein channel that lets things in and out of the cell






46. Used for reproductive purposes and peeing






47. Destoy the ozone layer






48. Has cones






49. A single cell made from the union of two gametes






50. Female part of the flower
