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.
1. 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






2. Special mechanoreceptors that allow you to sense temperature like hot and cold






3. The outer layer of a cell that serves as a wall to let food in and let waste out

5. A type of cell that has no nucleus and has all the genetic material surrounded by it






6. Uses the major arteries and veins to move oxygen rich blood throughout the body






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






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






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






10. The tube that is connected to the outside world






11. Warm - blooded and maintains a constant body temperature






12. A protein that an insect's exoskeleton is made out of






13. A long tube that connects the mouth to the stomach

15. A protist that captures food to eat - such as an amoeba - and are also known as protozoans






16. Jointed plates on an insect that are located in the abdomen and let in air so that an insect can breathe






17. A group of vertebrates that have dry scaly skin that protects them and keeps moisture inside their bodies and use lungs to breathe air






18. The long strands that DNA comes in. Two DNA molecules held together by a central structure






19. 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

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






22. The thick - milkshake consistency that food becomes once it is digested in the stomach

24. 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






25. Process in which glucose is broken down and is a catabolic reaction






26. The cell organelle that breaks down food and releases energy






27. Phase of mitosis - in which identical chromosomes seperate and move to opposite sides of the cell






28. The four pairs of chemical compounds that connect together in DNA






29. 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






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






31. Human body system that contains hormonal glands that control growth and reproduction






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






33. The body's liquid messenger that takes oxygen and nutrients to the body






34. Human body system that gets rid of chemical wastes by flushing them out






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






36. Cell organelle that breaks down food - cell waste and broken cell parts






37. Muscles tha allow you to move different parts of the body
