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. 'Water fearing' & repels water






2. Noncoding material






3. Triggers mitosis when it binds with cyclins at high enough concentrations & survives mitosis






4. 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






5. The DNA information being transferred to mRNA






6. A compound on the surface of animal cells that allow cells to recognize and interact with one another






7. Both dominant or recessive






8. The global movement of phosphorus between the abiotic environment and organisms






9. A long & unbranched hydrocarbon chain with a carboxyl group (COOH) at one end






10. Plant growth response that is not dependent on the direction of the stimulus






11. Lateral






12. A type of learning in which an animal learns to ignore a repeated & irrelevant stimulus






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






14. Morning after pill






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






16. The rate at which energy is captured during photosynthesis






17. A link formed when two amino acids combine






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






19. The average per capita birth rate






20. The enzyme that links the Okazaki fragments






21. A transitional zone where two or more communities meets & contains all or most of the ecological niches of the adjacent communities as well as some that are unique to the ecotone






22. Occurs when there is the same concentration in different areas






23. Controls the growth and development in animals






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






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






26. The use of cues to change direction when necessary to reach a specific destination






27. 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






28. The global movement of nitrogen between the abiotic environment and organisms






29. Going up and down around a set point






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






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






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






33. Initial fertilized cell






34. The rate at which energy is captured during photosynthesis






35. The start of a gene






36. High to low concentration






37. Very low precipitation






38. 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






39. Used for long term energy storage & cell membranes & padding and insulation & and steroids & soluble in nonpolar solvents and relatively insoluble in water






40. Towards the stimulus






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






42. Zygote after it has undergone mitosis and grown






43. Stores water in plants






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






45. Unzips the DNA strand






46. Involves mitosis and cytokinesis






47. Figured out that the hormone that made plants bend was on the opposite side from the light






48. The transmission of genetic information from parent to offspring






49. Thin inner membrane in a land egg






50. When the cell prepares itself for division
