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. Occurs when a segment of genetic material on a chromosome becomes reversed






2. A bundle of nerve axons






3. The basal branch of each spinal nerve; carries motor neurons






4. Waves of contraction and relaxation passing along a tubular structure - such as the digestive tube






5. The solid ball of cells the results from cleavage of an egg; a solid blastula that precedes the blastula stage






6. A constituent of the plasma of the blood of vertebrates; it is converted to thrombin by thrombokinase in the presence of calcium ions - thus contributing to the clotting of blood






7. A reproductive cell

10. The loss of all or part of a chromosome






11. The cavity in the mammalian ovary in which the egg ripens






12. A network of membrane-enclosed spaces connected with the nuclear membrane; transports materials through the cell; can be soft or rough






13. The individual differences of form among the members of a species






14. A period in the development of animals between the embryo and adult stages; starts at hatching and ends in metamorphasis

16. A bony or chitinous case or shield covering the back or part of the back of an animal (shell of a crab)






17. A sugar composed of two combined monosaccharides






18. Deoxyribonucleic acid; found in cell nucleus - its basic unit is the nucleotide; contains coded genetic information; can replicate on the basis of heredity






19. An association between an algae and a fungus that is symbiotic and mutualistic in nature






20. A symbol that denotes the relative concentration of hydrogen ions in a solution






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