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 DNA replicates






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






3. Growth response to physical disturbance & positive or negative






4. Where sperm is stored






5. Eggs and sperm combine






6. AAAA...






7. Opening into the uterus






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






9. The strand of DNA that is synthesized smoothly and continuously






10. When a cell or nucleus has only a single set of chromosomes






11. 'Water fearing' & repels water






12. The concentration is equal in both areas






13. When the cell prepares itself for division






14. 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






15. The ability of a community to withstand disturbances






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






17. A protein channel that lets things in and out of the cell






18. The study of heredity






19. A simple signal that triggers a specific behavioral response






20. Takes less energy and is more efficient than sexual reproduction






21. Secretes hormones that keep uterine lining thick in the event of fertilization & what the follicle turns into after fertilization






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






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






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






25. Away from the stimulus






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






27. Chemical messenger






28. An evolutionary modification that improves the chances of survival and reproductive success in a given environment






29. Contains two monosaccharide rings joined by a ether link






30. Contains two monosaccharide rings joined by a ether link






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






32. A common type of gene interaction in which the presence of certain alleles can prevent or mask the expression of a different allele and express their own phenotype instead






33. The local environment where a species lives






34. A stack of thylakoids






35. The study of heredity






36. A conservation approach that emphasizes restoring and maintaining the quality of an entire ecoystem rather than the conservation of individual species






37. Produces gonatotropin releasing hormone (GnRH)






38. Can make its own food






39. Produces semen (1)






40. An individual of unknown genotype is crossed with a homozygous recessive individual






41. Coding material






42. A link formed when three or more amino acids combine






43. Proposes that simple prokaryotic organisms began living in symbiotic relationships that eventually became obligatory (necessary) as one cell engulfed the other






44. Eggs laid and then fertilized






45. A compound present on the outer surface of cells that aren't bacteria






46. A process carried out to ensure that the male is actually male and a member of the same species






47. A community with the abiotic factors of the place






48. A stable and persistent community & is impossible to achieve because of disturbances






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






50. The concentration of water is higher than in the other area
