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. A fatty acid that doesn't contain the maximum possible number of hydrogens






2. Things that eat the primary consumers & third lowest trophic level






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






4. Behavior that is common to a population & learned from other members of the group & and transmitted from one generation to another






5. Going from areas of low to high concentration & goes against the concentration gradient & requires cell energy






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






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






8. Cold & dry & permafrost & treeless & short growing season






9. The constricted region in a chromatid






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






11. Triggers mitosis when it binds with cyclins at high enough concentrations & survives mitosis






12. Little 'hairs' around the membrane used for movement






13. Same organism makes both gametes & no genetic recombination






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






15. A mutation in which the entire reading chain is shifted & changed everything after an addition or delection






16. The number of species in a community






17. The average per capita death rate






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






19. Connects the ovary to the uterus & where fertilization usually takes place






20. The time when no cell division in occurs






21. Decompose all trophic levels






22. Noncoding material






23. A covalent link formed when the equivalent of a water molecule is removed as one of the glycerol's hydroxyl groups reacts with the carboxul group of a fatty acid






24. A plant structural compound






25. Gives live birth






26. Fertile soil & all grass






27. Kills sperm






28. A section of three nitrogenous bases






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






30. Stimulates the anterior pituitary to make FSH and LH






31. Species that are all undesirable resemble each other






32. Where protein synthesis takes place






33. 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






34. Where sperm is stored






35. Aka boreal forest & big evergreen forests & cold most of the year






36. A protein that accelerates the thousands of different chemical reactions that take place in an organism






37. Very low precipitation






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






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






40. Completes the preparation of the endometrium for pregnancy






41. Holds the ovules






42. Both dominant or recessive






43. When two parts of sister chromatids exchange corresponding parts






44. A single cell made from the union of two gametes






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






46. A disaccharide made from glucose and galactose & milk sugar






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






48. Stimulates contraction & prostaglandin release & and ejection of milk






49. The maximum rate at which a population of a given species could increase under ideal conditions & plenty of resources &and a low population density & is influenced by the age of reproductive maturity & how long the organism is able to reproduce & and






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