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.
1. Soft mass at the center of the tooth containing blood vessels and sensitive nerves






2. The spiky part of a sponge's skin that keeps it from being eaten






3. The way that eukaryotic cells divide to help cause growth. The nucleus of one cell divides into two identical nuclei






4. The shape that DNA is formed within






5. Muscles that move bones and work in teams to move the bones appropriately






6. 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






7. Undeveloped plants with stored food in a protective covering






8. Human body system made up of bones that hold the body up and protect the vital organs of the system






9. Hormones released from the adrenal glands during times of stress by telling the body to metabolize carbohydrates to produce extra energy






10. Algae with a special type of flagellate that allows them to spin in circles






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






12. Glands in the skin that produce sweat






13. The condition - if not treated - when the inflamed appendix breaks and releases bacteria to the body. It can cause organ failure and death






14. Meat - eating






15. Enzyme found in spit that breaks down carbohydrates






16. 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






17. Protozoas that live in host organisms without providing any benefits






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






19. Dome shaped muscle that the lungs rest on






20. Plant - like organisms that don't have roots - stems or leaves - but they have chlrophyll which allows them to do photosynthesis






21. How organisms are organized through evolution






22. The inabiliy to hear sound






23. Any place where two or more bones meet






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






25. Larger and flatter teeth in the back that are used to crush food to mix with saliva to make it easier to swallow






26. Three layers of connective tissue that protect the spinal chord






27. The millions of pairs of chemical compounds that make up DNA






28. Area surrounding spinal chord that has motorneurons responsible for voluntary movement and flexibility






29. Gymnoperm plants that produce male and female cones






30. Hormone released by the ovaries that cauess breast development - body shape changes - and menustration






31. Hormone released by the pituitary gland that stimulates cell division - causing growth






32. Animals that do not have a backbone - like butterflies - sand dollars - and starfish






33. Cells owned by plants and animals in which the cell's genetic material is surrounded by a membrane






34. A trait in heredity that does not appear as frequently in the offspring






35. A white - fatty substance that axons contain to speed up transmission of impulses






36. Little glands located in the abdomen of a spider to make silk for spider webs






37. Reptiles shed their skin to grow






38. Joint that is used by shoulders and arms. One bone ends in a ball shape that fits into the socket of the other bone






39. Animals with backbones or spinal columns - includes fish - mammals - amphibians - reptiles - birds

41. Layer of skin that is beneath the epidermis






42. The sum of an organism's genes






43. Muscle that pumps blood through your body and handles circulation






44. A thick hard layer of bone that is below the periosteum






45. Specialized mechanoreceptors in the ear that sense vibration and allow you to hear sound






46. A rod of stiffened tissue that develops into the backbone of a vertebrate as the animal grows






47. Big blocks of food that stay in the teeth and release bacteria






48. The dramatic change an animal goes through on its way to becoming an adult






49. The process in which plants turn water and carbon dioxide and sunlight into photosynthesis






50. Tubes that the urine from the kidneys travels through to the bladder
