Test your basic knowledge |

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






2. The end of a lineage






3. Cells are the basic unit of living organisms and all cells come from pre-existing cells






4. Noncoding material






5. 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






6. An economical form of reserve fuel storage which yields over two times more energy than carbs when metabolized






7. Stalk of the stamen






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






9. Original cell that forms egg






10. All the alleles present in the population






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






12. Morning after pill






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






14. Organizes the cell for purposes of cell division






15. The strand of DNA that is always growing away from the replication fork & so only short pieces can be synthesized






16. Destoy the ozone layer






17. Cutting of vas deferens






18. Initial shoot that comes out of the ground






19. Species that show repetitive reproductive cycles






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






21. Up or down






22. The time when no cell division in occurs






23. A grid that shows the possible combinations of alleles






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






25. Grow and divide asexual reproduction






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






27. Growth response to gravity & positive in stem & negative in roots






28. Immature sperm cell






29. Release of the egg






30. The number of individuals of a species per unit of area or volume at a given time






31. More cells






32. Different traits are passed on separately and independently from one another






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






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






35. Reproductive isolation due to structural differences






36. Initial fertilized cell






37. The ability to produce viable offspring






38. Stimulates the anterior pituitary to make FSH and LH






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

41. Megasporocyte after meiosis






42. Eggs laid and then fertilized






43. Quantitative estimate of the total mass & the amount of living material






44. Plastic cover of the penis






45. Aka chaparral & mixed scrub community with lower rainfall than in a deciduous forest






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






47. 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






48. 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






49. The ability to produce viable offspring






50. The rate at which energy is captured during photosynthesis
