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 interactions of tertiary structures






2. An organic compound with 3-7 carbons with a hydroxyl (OH) group bonded to each but one & which is double bonded to an oxygen






3. Each gene is present in two copies & when gametes are formed each gamete gets only one of the two factors






4. Used for reproductive purposes and peeing






5. Changes that take place over very long periods of time that may result in speciation






6. A chain produced by likening small organic compounds called monomers






7. Provides genetic variation through recombination






8. A disaccharide made from two glucoses & malt sugar






9. Contains multiple monosacharides bonded together & consists of repeating units of simple sugars






10. Gives live birth






11. When there is equilibrium between to areas & but molecules are still moving






12. All the Earth's communities and their interactions and connections with the planet's abiotic factors






13. The layer that surrounds the cell and holds everything in






14. Cells don't produce new cytoplasm to make the cell bigger & they produce an excess of protons which soften the cell walls so that the water vacuole fills up and makes the cell bigger






15. Regulates the ecosystem function by nutrient cycling and by availability of other resources






16. A vacuole filled with digestive enzymes






17. On the side where the 5' carbon is

21. Pressure the cell membrane exerts on the cell wall when the water vacuole is filled






22. The DNA information being transferred to mRNA






23. Where protein synthesis takes place






24. Reproductive successfulness






25. The study of behavior in natural environments from an evolutionary perspective






26. Where cells are actively dividing






27. Have traits that contribute to a high population growth rate & usually small & reach maturity early & have short life span & have lots of offspring & provide little to no parental care






28. Produces proteins






29. A stable and persistent community & is impossible to achieve because of disturbances






30. A mutation in which the wrong base it transcribed






31. Lateral






32. Little 'hairs' around the membrane used for movement






33. A single ringed nitrogenous base






34. Where DNA is held & the control center of the cell






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






36. Plastic cover of the penis






37. The nuclear division that produces two nuclei containing chronosomes identical to those in the parental nucleus






38. A link formed when two amino acids combine






39. Exactly the same as mitosis






40. Plant growth response that is dependent on the direction of stimulus






41. An organic compound consisting of only carbon and hydrogen






42. When two parts of sister chromatids exchange corresponding parts






43. Produces semen (2)






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






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






46. Defense of a territory






47. Provides food for the developing embryo in a land egg






48. One dominant and one recessive






49. The divergence of two similar species living in the same geographic area






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