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. The change in species composition produced at ecotones






2. A group of the populations of all the different species in an area






3. 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

12. Going from areas of high concentration to low concentration & going with the concentration gradient






13. All the alleles present in the population






14. The amount of energy that remains in plant tissues after cellular respiration & the amount of biomass found in excess of that broken down by a plant's cellular respiration for normal daily activities

16. Reproductive successfulness






17. A phospholipid bilayer in which the layers are oriented towards each other and there are proteins on the outside of and in between the layers

19. A parasite that lives inside the host






20. Transmits hereditary information and determines what proteins a cell manufactures






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






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






23. The study of heredity






24. Provides genetic variation through recombination
