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 symbiotic relationship from which both organisms involved derive some benefit






2. The ability to respond to a stimulus






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






4. A marine biome; a region on the continental shelf that contains an ocean area with depths of up to 600 ft






5. The system of naming an organism by its genus and species name






6. Describes organisms that are cooperative in action - such as hormones or other growth factors that reinforce each other's activity






7. Describes structures that have similar function but different evolutionary origins; e.g. - a bird's wing and a moth's wing






8. A cell in the retina that is sensitive to weak light






9. xylem that is no longer being used






10. Describes an individual that has the same gene for the same trait on each homologous chromosome






11. The inner part of the adrenal gland that secretes adrenalin






12. Genetic blending; each allele exerts some influence on the phenotype






13. A structure of the eye that focuses images on the retina by changing its convexity






14. Usually referred to as ACTH and secreted by the anterior lobe of the pituitary gland; stimulates the adrenal cortex to produce its characteristic hormones






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






16. The conversion of digested foods and other materials into forms usable by the body (i.e. - the conversion of amino acids into proteins)
