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.

16. A sex or reproductive cell that must fuse with another of the opposite type to form a zygote






17. The coagulation of blood caused by the rupture of platelets and the interaction of fibrin - fibrinogen - thrombin - prothrombin and calcium ions






18. An air-conducting tube






19. A sensory hair structure in the utriculus and the sacculus of the inner ear; orients the head with respect to gravity






20. Compounds in bile that aid in emulsification

26. The primary germ layer - developed from the lip of the blastopore - that gives rise to the skeleton - the circulatory system and many organs and tissues between the epidermis and the epithelium
