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. Occurs when there is the same concentration in different areas






2. The start of a gene






3. Produces proteins






4. The evolutionary diversification of many related species from one or more ancestral species in a relatively short period






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






6. When an original part of the double helix is put together with a new strand & and the same is done with the other part of the original






7. The global movement of carbon between the abiotic environment and organisms






8. The time when no cell division in occurs






9. The net energy available for biomass production by consumer organisms






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






11. A stack of thylakoids






12. Implanted in the uterus & probably stimulates inflammatory response and prevents implantation






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






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






15. A graph that illustrates the total biomass at each successive trophic level






16. Stable relationships that ensure cooperative behavior in mating and the rearing of the young






17. A behavior that has been modified in response to environmental experience






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






19. 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






20. Exactly the same as mitosis






21. The structure in the mitochondria






22. Contains two monosaccharide rings joined by a ether link






23. Connects the testis to the penis






24. Compounds with the same molecular formulas but different structures






25. Any environmental factor that affects the size of a population but isn't influences by changes in population density & usually abiotic factors






26. Partner chromosomes similar in size & shape & and the position of their centromeres (XX)






27. Oscillation between two things that affect the population & keeps the population in check






28. A mutation in which the wrong base it transcribed






29. Gases act like a blanket and hold heat in the atmosphere






30. Connects the testis to the penis






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






32. A combination of natural selection and genetics






33. A plant structural compound






34. Going up and down around a set point






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






36. Plants & make their own food & lowest trophic level






37. When an original part of the double helix is put together with a new strand & and the same is done with the other part of the original






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






39. Pressure the cell membrane exerts on the cell wall when the water vacuole is filled






40. 'packages' cell products






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






42. The person that said that the human population would quickly outgrow the natural resources and that it would cause war






43. A group consisting of members of the same species that live together in a prescribed area at the same time






44. The nuclear division that produces two nuclei containing chronosomes identical to those in the parental nucleus






45. 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






46. Spontaneous generation & life may arise from nonliving matter (incorrect idea)






47. Where cell aerobic respiration takes place






48. Where sperm cells are formed by spermatogenesis






49. Coccus prokaryotic cells






50. A link formed when two amino acids combine
