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. Speciation that occurs when a new species evolves within the same geographic region as the parental species






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






3. A structure that separates the duplicated chromosomes during anaphase






4. A scientific discipline with ties to evology that focuses on how humans interact with the environment






5. The complex formed when the enzyme and substrate combine






6. The proportion of a specific allele in a particular population






7. The probability of survivorship doesn't change with age






8. Composes the genes and contains the instructions for making all the proteins & as well as the RNA & an organism needs






9. Kills sperm






10. The beta pleated sheet or alpha helix






11. When one individual behaves in a way that seem to benefit others rather than itself






12. A long & unbranched hydrocarbon chain with a carboxyl group (COOH) at one end






13. Produces gonatotropin releasing hormone (GnRH)






14. Coccus prokaryotic cells






15. A type of natural selection for successful mating






16. 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






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






18. 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






19. A graph of the number of organisms at each trophic level in a given ecosystem






20. The interactions of tertiary structures






21. The buildup of predator and prey strategies






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






23. The potential ecological niche of a species






24. A disaccharide made from two glucoses & malt sugar






25. A macromolecule composed of amino acids






26. Female part of the flower






27. Exactly the same as mitosis






28. Reproductive successfulness






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






30. Aka aggregated distribution & occurs when resources in an area are clumbed & when there is limited seed dispersal or asexual reproduction & or when families/colonies all live together & good because the organisms can protect one another






31. Cutting of vas deferens






32. Fossil record






33. Unfertilized egg develops into a reproducing haploid animal that is capable of reproducing using a different process to make gametes






34. 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






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






36. Abstinence during ovulation period






37. Both individuals have male and female parts but don't self fertilize






38. 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






39. Very low precipitation






40. Both extremes are better than average






41. Camouflage






42. Reproductive isolation due to different habitats in the same area






43. Both extremes are better than average






44. Produces proteins






45. Zygote after it has undergone mitosis and grown






46. The constituent of a protein & has an amino group (NH2) and a carboxyl group (COOH) bonded to the same alpha carbon






47. Compounds with the same molecular formulas but different structures






48. The rate at which energy is captured during photosynthesis






49. When there is equilibrium between to areas & but molecules are still moving






50. Involves persistent changes in behavior that result from experience
