CSET Science: Biology

Subjects : cset, 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.

10. Human body system that exchanges carbon dioxide for oxygen for breathing






11. Heart chamber that pumps the blood out of the heart






12. Helps scientists predict heredity from cross - breeding






13. The way that a polyp - a cnidarian - reproduces asexually by growing a small version of the plant called a bud that evenetually becomes its own organism






14. Angiosperms that have two seed leaves inside their seeds






15. The flow of blood within the heart itself






16. An extension of the brain that determines smells based on the scents picked up by the cilia in the olfactory membrane






17. A type of vertebrate that monitors their body temperature so it stays constant no matter where they are - like birds






18. Organ that digests food with enzyme and other digestive juices like hydrochloric acid






19. A carnivorous plant with sticky beads that attract insects and then sucks the nutrients out of their decaying bodies






20. A type of amphibian thath as a long body - short legs and flattened tails for swimming






21. Plants that grow up to live for many seasons and reproduce multiple times






22. Protozoans that move with a flagellum and live in the water






23. The inabiliy to hear sound






24. Photoreceptive nerve cells that are sensitive to light and can be triggered by a single photon






25. The larger organ that follows the small intestine in digestion which absorbs water from the remaining chyme

27. Joint found in the knees that are less flexible but much more stable






28. The fluid filled gap that axons are connected to in the neuron






29. Photoreceptive nerve cells that are less light sensitive and can detect color






30. Eyes that some insects may have that haveh undreds of lenses that allow an insect to see many things at once






31. The idea that the earliest forms of living organsims were made out of RNA and not DNA. Life forms based on RNA evolved to the life forms that we see today






32. Phase of mitosis in which the chromosomes are visible and centrioles move to the opposite ends of the cells and threadlike spindle fibers start to spread across

34. A protozoa that cannot move on its own and depends on living bodies for transport






35. The walls of a plant cell






36. The first part of the small intestine where digestive enzymes from liver and pancreas break up chyme into a soup of molecules small enough to enter the bloodstream






37. The center of the chromosome that holds the structure together






38. Phase of mitosis - in which spindle fibers start to disappear and it becomes harder to see them and each of the seperated chromosomes creates a separate nucleus to






39. A protein that binds with molecules - called the antigen - that is found on the invading germ. the protein signals white blood cells to kill the invading germ






40. Phase of mitosis in which the duplicated chromosomes line up along the center of the cell and each centromere attaches to two spindle fibers
