CLEP Biology

Subjects : clep, 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. Is composed of an anterior and posterior lobe. The stalk of the lobe is connected to the hypothalamus. Antidiuretic Hormone (AH) is produced in the hypothalamus and stored in the posterior pituitary. Upon nervous stimulation from the hypothalamus - t






2. Respiratory organs within insects






3. When stems bend toward the light it is due to _____________ the hormone auxin - in response to light - migrates from the light to the dark side of the shoot tip. The cells on the dark side now contain more auxin - which causes the cells on that side






4. Controls balance and muscle coordination






5. A reaction that adds water to another compound. (2 hydrogens - 1 oxygen).






6. Absorb a photon of light and is found in the grana of the chloroplast.






7. The solid mass of cells resulting from the cleavage of the ovum before the formation of a blastula.






8. Has an equal (50%) chance of being passed from a carrier mother to a son or a daughter.






9. An orienting response to light.






10. The cells of a developing embryo (at the gastrula stage) differentiate into layers - that will later develop into different tissues and organs - including the mesoderm - ectoderm - and endoderm.






11. Refers to the birthrate of a population.






12. Is the sugar that lactase acts upon.






13. Is a kind of plain characterized by a warm climate - grassland - and seasonally dry climate conditions.






14. Controls sensory and motor responses - and controls memory - speech - and intelligence factors.






15. Carbon - nitrogen - phosphorous - and water. These are all recycled through biogeochemical processes.






16. Is found on the stem between nodes.






17. Veins in the leaf and are also distributed throughout the stem






18. Has extreme hot or cold temperatures - with very low precipitation - sandy or rocky terrain - sparse vegetation (mainly succulents) - small animals - rodents - and reptiles.






19. The effect of a substrate concentration on the initial reaction rate in the presence of a limited amount of enzyme: _________________ as the concentration of substrate is increased until all the enzymes are used - then the reaction rate will level of






20. Is comprised of all the organisms that interact within a given ecosystem whether or not it is at carrying capacity.






21. Allows for the genetic code to be preserved in future generations of cells.






22. Is a behavior that is learned during a critical point (often very early) in an individual's life. Imprinting enables the young the recognize members of their own species.






23. Studied the relationships between traits expressed in parents and offspring and the genes that caused the traits to be expressed.






24. Is very rare and is not absorbed by plant leaves. Phosphorous is nearly always found in solid form.






25. A length of DNA (with corresponding histones) is responsible for the production of a certain protein that causes a particular trait to be expressed in an organism.






26. Is disorganized - unravelled - DNA with histones attached.






27. In DNA Guanine pairs with...






28. Contains optic lobes - controls sight.






29. Plants and animals obtain usable nitrogen






30. Are more closely related to Homo Sapiens than to other apes - but Homo Sapiens did not evolve from chimpanzees.






31. Anabolism






32. Secretes insulin to lower blood sugar and maintain equilibrium. A person eats three candy bars. Within minutes this endocrine gland affects blood-glucose homeostasis.






33. The bronchi lead to the two lungs where they branch out in all directions into smaller tubules known as bronchioles.






34. High temperatures






35. Inorganic phosphate






36. Is a protein - which is a polymer of amino acids. They generally have the suffix -ase- like lactase.






37. Are produced when water passes through the cell membrane by osmosis from an area of higher concentration to an area of lower concentration - to equalize water concentration.






38. Occurs when an individual learns not to respond to a particular stimulus - for instance when a stimulus is repeated many times without consequence.






39. Protein synthesis






40. The trachea includes the windpipe or larynx in its upper portion - and the glottis - an opening that allows the gases to pass into the two branches known as the bronchi.






41. Are where the sugars synthesized by photosynthesis travel through to various parts of the plant.






42. The vocal cords are found in the larynx.






43. States that where random mating is occurring within a population that is in equilibrium with its environment - the gene frequencies and genotype ratios will remain constant from generation to generation. It is a mathematical formula that shows why re






44. The transfer of electrons.






45. In both living and non-living environments.






46. Proposes that those individuals within a population that are most adapted to the environment are also the most likely individuals to produce viable offspring.






47. The phyla composed of segmented worms.






48. Is secreted by the adrenal cortex to promote sodium reabsorption in the kidney.






49. An enzyme is unaffected by the reactions it catalyzes






50. Contain organisms that are multicellular eukaryotes including vertebrates and invertebrates.
