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 fat or oil






2. A group of life-maintaining processes that includes nutrition - respiration (the production of usable energy) and the synthesis and degradation of biochemical substances






3. The female gamete; it is nonmotile - large in comparison to male gametes - and stores nutrients






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






5. Secreted by the anterior pituitary gland - this hormone stimulates the conversion of a follicle into the corpus luteum and the secretion of progesterone by the corpus luteum






6. The place of attachment of the mitotic fiber to the chromosome






7. The central tissue of a stem - used for food storage






8. The haploid - sexual stage in the life cycle of plants






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






10. Any movement or growth of a living organism in response to the force of gravity






11. An organism that possesses one or more whiplike appendages called flagella






12. A plant that lives on another plant mensalistically






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






14. A type of nuclear division that is characterized by complex chromosomal movement and the exact duplication of chromosomes; occurs in somatic cells






15. A thyroid deficiency that results in stunted growth and feeblemindedness






16. The smallest particle that is capable of carrying out photosynthesis; the functional unit of a chloroplast






17. An ion with a positive charge - or an ion that migrates towards the cathode (negative electrode) in an electric field






18. A multidirectional sensory system of lower animals such as the hydra - consisting of nerve fibers spread throughout the ectoderm






19. A protein compound containing iron that is found in red blood cells






20. A starch form in animals; glucose is converted to this in the liver






21. A network or mesh of fibrils - fibers or filaments

23. An organ centrally involved in the human digestive system






24. Involuntary muscle






25. A cell that divides to form the polar body and the secondary oocyte

27. A sugar composed of two combined monosaccharides






28. The state in which two genetic traits are fully expressed and neither dominates






29. A mass of cells that have similar structures and perform similar functions






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






31. A process of cell division whereby each daughter cell receives only one set of chromosomes; the formation of gametes






32. The living together of two organisms in an intimate relationship






33. The largest portion of the human brain; it is believed to be the center of intelligence - conscious thought and sensation






34. Partially digested food in the stomach






35. An organic compound to which hydrogen and oxygen are attached; the hydrogen and oxygen are in a 2:1 ratio; examples include sugars - starches and cellulose
