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. When the heterozygote has a phenotype intermediate between those of its two parents






2. A gene carried on the Y chromosome






3. Energy from food passing from one organism to the next in a sequence






4. Provides food for the developing embryo in a land egg






5. A fatty acid that contains the maximum possible number of hydrogens






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






7. Covalently linking monomers






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






9. Eggs and sperm combine






10. Daily & 24 hour cycles of activity






11. Makes up the cytoskeleton

20. The major carrier of genetic information in eukaryotes & found in the cell nucleus






21. Towards the stimulus






22. The study of how living organisms and the physical environment interact in an immense and complcated web of relationships & the broadest field of biology






23. Moving molecules into a cell






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






25. One dominant and one recessive






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






27. The time inbetween meiosis 1 and 2






28. The site of photosynthesis






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






30. Choosing certain trains and breeding only individuals that axhibited the desired traits






31. The end of a lineage






32. Competition among population of different species






33. The DNA information being transferred to mRNA






34. The buildup of a toxin in an organism's body






35. The empty space in the ER tubes






36. What something does and how it does it






37. 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






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






39. Found out that the hormone was being produced in the tip






40. The change in allelic frequencies of two or more populations over time & the interdependent evolution of two or more interacting species






41. A mating system in which a male mates with only one female during a breeding season






42. When a population's allele and genotype frequencies don't change from generation to generation






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






44. 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






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






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






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






48. CAT






49. Has cones
