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. Chemical groups attached to carbon skeletons that give compounds their functionality






2. A process of asexual reproduction in which the offspring develop from an outgrowth of the plant or animal






3. The breeding of an organism with a homozygous recessive in order to determine whether an organism is homozygous dominant or heterozygous dominant for a given trait






4. Three membranes that envelop the brain and spinal cord (pia mater - dura mater and arachnoid)






5. The outermost bone of the middle ear (hammer)






6. A condition in which an organism may have a multiple of the normal number of chromosomes (4n - 6n - etc)

19. A mucus-secreting membrane






20. A bundle of nerve axons






21. Occurs when certain traits are determined by genes on sex chromosomes






22. Describes cells that have a double set of chromosomes in homologous pairs (2n)






23. A structure that arises during mitosis and helps separate the chromosomes; composed of tubulin






24. A cell resulting from the fusion of gametes






25. The study of form and structure
