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.

13. An intimate relationship or association between members of two or more species






14. The change in species composition that takes place after some disturbance removes the existing vegetation & but the soil remains






15. The strand of DNA that is always growing away from the replication fork & so only short pieces can be synthesized






16. All of the contents of the cell inside the membrane






17. The mating of genetically similar individuals that are more closely related than if they had been chosen at random from the entire population






18. A link formed when two amino acids combine






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






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






21. Inhibits ovulation & lasts a long time






22. A main component of cell walls of fungi and of the external skeletons of insects & crayfish & and other arthropods






23. When the animal must do something to gain a reward or to avoid punishment






24. When most are average and extremes are better






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






26. Plant growth response that is not dependent on the direction of the stimulus






27. 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






28. A channel that takes things from one side of the phospholipid bilayer to the other by having a protein attach to the channel which changes its shape and moves the stuff to the other side






29. TATA






30. Produces follicle stimulating hormone (FSH) and luteinizing hormone (LH)






31. The end of a lineage






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

43. Produces gonatotropin releasing hormone (GnRH)






44. Involves mitosis and cytokinesis






45. A system of tubes and tubules used for internal storage and transport of proteins






46. Used for reproductive purposes and peeing






47. The role of an organism within the structure and function of a community & takes into account all biotic and abiotic aspects of the species & as well as all the physical & chemical & and biological factors that it needs to survive & its habitat & wha






48. Controls the growth and development in animals






49. Fluid filled sac where the primary oocyte divides to form the secondary oocyte and the polar body






50. The local environment where a species lives
