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. Focuses on the evolution of social behavior through natural selection






2. A single strand of RNA that folds back on itself to form a specific shape






3. What something does and how it does it






4. Flowering plant






5. Holds the ovules






6. Stimulates the growth of sex organs at puberty and the development of secondary sex characteristics & induces maturation & stimulates monthly preparation of endometrium for pregnancy & makes cervical mucus thinner and more alkaline






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






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






9. A form of active transport that uses energy to pump ions from the outside to the inside of a cell






10. Lining of the uterus






11. An actively cooperating group of individuals belonging to the same species and often closely related






12. Response of any plant to the amount of light it receives






13. Focuses on the evolution of social behavior through natural selection






14. The global movement of water between the abiotic environment and organisms






15. Camouflage






16. Where sperm cells are formed by spermatogenesis






17. When females select their mates on the basis of some physical trait or some resource offered by the winning suitor






18. The arrival of the chromosomes at the poles and cytokinesis






19. Going up and down around a set point






20. Organizes the cell for purposes of cell division






21. A species that is crucial in determining the nature of the entire community and that greatly affects the rest of the community & keeps the who ecosystem in balance






22. Exactly the same as mitosis






23. New genetically identical 'self' grows on the side and then breaks off






24. 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






25. Speciation that occurs when one population becomes geographically separated from the rest of the species and subsequently evolves by natural selection/genetic drift






26. Daily & 24 hour cycles of activity






27. Local variation in climate produced by differences in elecation






28. 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






29. Species that show repetitive reproductive cycles






30. Genes that tend to be inherited together






31. Coccus prokaryotic cells






32. Collects waste products in a land egg






33. A grid that shows the possible combinations of alleles






34. A tool of ecological management in which the undergrowth and plant litter are deliberately burned under controlled condition before they accumulate to dangerous levels






35. The young have a high probability of surviving & which the old have a much lower probability






36. A species that affects the community because it is very common






37. Initial shoot that comes out of the ground






38. Connecting trunk of the pistil






39. The study of heredity






40. When individuals in a population are spaced throughout an area in a way that is unrelated to where other are & the least common type of dispersion






41. Larger cells






42. The interactions of tertiary structures






43. Aka scramble competition & all the members of the population have a generally equal amount of the resources






44. A periodic long-distance travel from one location to another






45. Inhibits ovulation & affects the endometrium and cervical mucus to prevent implantation & regulates the menstrual cycle






46. A large & relatively distinct terrestrial region that has similar climate & soil & plants & and animals regardless of where it occurs






47. Reproductive successfulness






48. Original cell that forms sperm






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






50. When individuals of the same sex actively compete for mates
