SAT Subject Test: Biology

Subjects : sat, science, biology
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 progressive change from which a permanently more mature or advanced state results






2. Any cell capable of ingesting another cell






3. An antipathogenic substance (e.g. - penicillin)






4. A terrestrial habitat zone that is characterized by large tracts of coniferous forests - long and cold winters - and short summers






5. Nonfunctional haploid cells created during meiosis in females; they have very little cytoplasm-most has gone into the functional egg cell






6. A pyrimidine component of nucleic acids and nucleotides; pairs with adenine in DNA






7. The study of the evolutionary descent and interrelations of groups of organisms






8. An organ that stores urine temporarily before it is excreted






9. Functional urinary tubules responsible for excretion in the kidney of vertebrates






10. The outermost surface of an organism






11. The science of classification of living things






12. A plant that has two seed leaves or cotyledons






13. Unicellular organism with simple cell structure






14. The class of free-living flatworms






15. A type of anaerobic respiration found in fungi - bacteria and human muscle cells






16. Globular proteins produced by tissues that destroy or inactivate antigens






17. A process of cell division whereby each daughter cell receives only one set of chromosomes; the formation of gametes






18. The fluid that remains after fibrinogen is removed from the blood plasma of vertebrates






19. The female gamete; it is nonmotile - large in comparison to male gametes - and stores nutrients






20. The extraembyonic membrane of birds - reptiles and mammals that serves as an area of gaseous exchange and as a site for the storage of noxious excretion products
