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. An organelle that regulates cell functions and contains the genetic material of the cell






2. In taxonomy - a classification between species and family






3. The chamber in the alimentary canal of certain vertebrates located below the large intestine - into which the ureter and reproductive organs empty (as in frogs)






4. A microscopic - whiplike filament that serves as a locomotor structure in flagellate cells






5. An organic catalyst and protein






6. The stable - biotic part of the ecosystem in which populations exist in balance with each other and with the environment






7. An offspring that is heterozygous for one or more gene pairs






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






9. A resistance to disease produced through the injection of antibodies






10. A wall composed of cellulose that is external to the cell membrane in plants; it is primarily involved in support and in the maintenance of proper internal pressure






11. A cell that divides to form the polar body and the secondary oocyte






12. The dorsal part of the hip girdle






13. Laws of classical genetics established through Mendel's experiments with peas






14. In mammals - the slitlike opening formed by the vocal folds in the larynx






15. The transfer of a piece of chromosome to another chromosome






16. A nerve cell






17. The male gonads that produce sperm and male hormones






18. An abbreviation of nicotinamide-adenine-dinucleotide-phosphate - also called TPN; an organic compound that serves as an oxidation-reduction molecule

20. A kind of white blood cell in vertebrates that is characterized by a rounded nucleus; involved in the immune response






21. The site of most digestion of nutrients and absorption of digested nutrients






22. The hormone secreted by the corpus luteum of vertebrates and the placenta of mammals; its function is to maintain the endometrium

31. Agent that induces mutations; typically carcinogenic






32. Compounds in bile that aid in emulsification
