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. One of a class of organic compounds that is composed of many amino acids; contains C - H - O and N






2. A category of taxonomic classification that is ranked above class and under kingdoms






3. An enzyme that acts upon maltose and converts it into glucose






4. The separation of some members of a population from the rest of their species; prevents interbreeding and may lead to the development of a new species






5. Pertaining to a restricted locality; ecologically - occurring only in one particular region






6. The study of organisms in relation to their environment






7. The coiled part of the sperm duct - adjacent to the testes in mammals






8. An abbreviation of nicotinamide-adenine-dinucleotide - also called DPN; a respiratory oxidation-reduction molecule






9. A specialized structure that leads to the digestive tract of a developing organism and provides it with food during early development






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






11. Organelles that serve as specialized containers for metabolic reactions






12. The process by which carbohydrates are formed through chemical energy; found in bacteria






13. In plants - an area of undifferentiated tissue covered by embryonic leaves






14. One or two or more types of genes - each representing a particular trait; many alleles exist for a specific gene locus






15. An organism that does not require free oxygen in order to respire






16. The vascular tissue of a plant that transports organic materials (photosynthetic products) from the leaves to other parts of the plant






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






18. A hormone that regulates water reabsorption






19. The intake of fluid droplets into a cell






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






21. A plant growth hormone






22. A simple sugar






23. Tissue formed by the differentiation of cambium that causes a growth in width of a plant system






24. A carbohydrate that is composed of many monosaccharide units joined together






25. Blood vessels located between ascending and descending aortas that deliver blood to most of the upper body






26. The external opening of the trachea in insects






27. Different relationships that are formed in proteins between the original sequence of amino acids and more complex three-dimensional compounds






28. The extraembryonic membrane in birds - reptiles and mammals that surrounds the embryo - forming an amniotic sac






29. In mammals - a flap of tissue above the glottis; it folds back over the glottis in swallowing to close the air passages of the lungs; contains elastic cartilage
