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. Tubules that excrete metabolic wastes into the hindgut in arthropods






2. A process of formation of ova






3. Describes a fluid that has a higher osmotic pressure than another fluid it is compared to






4. A female sex hormone secreted by the follicle






5. An organic molecule consisting of joined phosphate - 5-carbon sugar (deoxyribose or ribose) - and a purine or a pyrimidine (adenine - guanine - uracil - thymine or cytosine)

11. A remnant of follicle after ovulation that secretes the hormone progesterone






12. A blood vessel that carries blood back to the heart from the capillaries






13. The stage in mitosis that is characterized by the migration of chromatids to opposite ends of the cell; the stage in meiosis during which homologus pairs migrate (Anaphase I) - and the stage in meiosis during which chromatids migrate to different end






14. A stage of embryonic development in which the embryo consists of a hollow ball of cells

18. The uppermost portion of pistil upon which pollen grains alight






19. A nuclear protein of chromosomes that stains readily






20. A plant-eating animal






21. A cell that divides to form two secondary spermatocytes






22. An abbreviation of nicotinamide-adenine-dinucleotide-phosphate - also called TPN; an organic compound that serves as an oxidation-reduction molecule






23. The liquid part of blood

25. The largest artery; carries blood from the left ventricle






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