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. Towards the stimulus






2. Shows the mortality and survival data of a population






3. Species that show repetitive reproductive cycles






4. The amount of energy that remains in plant tissues after cellular respiration & the amount of biomass found in excess of that broken down by a plant's cellular respiration for normal daily activities






5. 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






6. A simple signal that triggers a specific behavioral response






7. Chemical messenger






8. When cells touch each other and stop dividing






9. The production of gametes






10. A link formed when three or more amino acids combine






11. Unzips the DNA strand






12. Reproductive isolation due to different mating times






13. 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






14. Plastic cover of the penis






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






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






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






18. Used for reproductive purposes and peeing






19. More cells






20. The end of a lineage






21. Holds the cell in place and gives it structure






22. More cells






23. The division of the cell cytoplasm to form two cells






24. When a molecule attaches to the channel and the carrier 'somersaults' to the other side and releases the molecule & then returns to its original side






25. Causes rapid cell division






26. Destoy the ozone layer






27. A single ringed nitrogenous base






28. Has its own life support for the embryo






29. A conservation approach that emphasizes restoring and maintaining the quality of an entire ecoystem rather than the conservation of individual species






30. A mutation in which the wrong base it transcribed






31. A link formed when three or more amino acids combine






32. A community with the abiotic factors of the place






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






34. 'Water fearing' & repels water






35. Fluid filled sac where the primary oocyte divides to form the secondary oocyte and the polar body






36. Where cells are actively dividing






37. The cycle that goes from oen organism to another in food chains and from living organisms to the abiotic environment and back






38. Initial fertilized cell






39. Where sperm is stored






40. Occurs when the environment is worsening from too many people






41. Opening into the uterus






42. Chemical messenger






43. Contains enzymes that help with fertilization






44. When individuals are evenly spaced & occurs because of territoriality or competition for resources or space






45. The DNA information being transferred to mRNA






46. Contains two monosaccharide rings joined by a ether link






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






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






49. Lining of the uterus






50. A combination of natural selection and genetics
