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






2. Coccus prokaryotic cells






3. Connects the baby to the placenta






4. Local variation in climate produced by differences in elecation






5. When most are average and extremes are better






6. A disaccharide made from glucose and fructose & table sugar






7. A combination of glycolipids and glycoproteins which is found on the outside of a cell and allows for cell-cell recognition






8. The constituent of a protein & has an amino group (NH2) and a carboxyl group (COOH) bonded to the same alpha carbon






9. The concentration of water is higher than in the other area






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






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






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






13. Stimulates the interstitial cells to secrete testosterone in males & stimulates ovulation and the development of the corpus luteum in females






14. A double ringed nitrogenous base






15. When two parts of sister chromatids exchange corresponding parts






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






17. Chemical messenger






18. Implanted in the uterus & probably stimulates inflammatory response and prevents implantation






19. The study of the past and present geographic distribution of organisms






20. Leaves right around the base of the flower that contains the flower






21. Provides structure for the cell






22. New genetically identical 'self' grows on the side and then breaks off






23. Local variation in climate produced by differences in elecation






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






25. Going through protein channels with the concentration gradient






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






27. The time inbetween meiosis 1 and 2






28. The information from the mRNA being used to form a protein

41. Individual & population & community & ecosystem & landscape & biosphere






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






43. Have trains that maximize the chance of surviving in an environment where the number of individuals is the carrying capacity & have few offspring & are larger & have long life spans & develop slowly & reproduce late & have low reproductive rates & pr






44. 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






45. Camouflage






46. Cut down trees and then burn them & pollutes the air & 'kills' the soil






47. A lipid that consists of carbon atoms arranged in four attached rings & three of which are hexagonal and the other is pentagonal

49. Completes the preparation of the endometrium for pregnancy






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