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. Light sensitive chemical






2. Produces semen (1)






3. The idea that evolution takes place in relatively short bursts of rapid change followed by long periods of stability






4. States that species richness is greatest at moderate levels of disturbance & so all the different species are at different stages in succession






5. The genetic drift that results when a small number of individuals from a large population found a new colony






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






7. Organizes the cell for purposes of cell division






8. Has cones






9. The stuff in between the granum






10. Both dominant or recessive






11. States that species richness is greatest at moderate levels of disturbance & so all the different species are at different stages in succession






12. Going through protein channels with the concentration gradient






13. The cells that don't become eggs in oogenesis






14. Lays eggs






15. Contain identical & double stranded DNA sequences (><)






16. The end of a gene






17. Involves mitosis and cytokinesis






18. Decompose all trophic levels






19. The number and types of species present & the relative abundance of each species & the interactions between different species & the resilience to disturbances & energy and nutrient flow & productivity






20. Emphasizes species individuality & shows how each species has its own abiotic living requirements






21. The end of a gene






22. The study of changes in a population (how and why the population numbers increase and decrease)






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






24. An important part of the structure of ribosomes that has catalytic functions needed during protein synthesis






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






26. Capillary bed that is adjacent to the capillaries of the uterine lining & exchanges everything except for blood






27. The enzyme that links the Okazaki fragments






28. Coccus prokaryotic cells






29. Abstinence during ovulation period






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






31. A nucleic acid polymer consisting of nucleotide subunits that can associate by complementary base paining with the single-strand DNA template






32. An arm of an amoeba






33. Microsporocyte after meiosis






34. Associates strongly with polar water molecules






35. The accelerating population growth rate that occurs when optimal conditions allow a constant per capita growth rate






36. A parasite that lives on the outside of the host






37. Grasses and scattered trees & less precipitation than in grasslands






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






39. Stores water in plants






40. The buildup of predator and prey strategies






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






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






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






44. Stores water in plants






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






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






47. Eggs laid and then fertilized






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






49. Completes the preparation of the endometrium for pregnancy






50. The ability to produce viable offspring
