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 the outermost of the three main layers of an embryo.






2. Transparency - polarity - high specific heat - and density (lower density when solid than when liquid.).

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






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






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






21. Controls hunger and thirst






22. Some enzymes contain a __________ component that is essential to their functions.






23. 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

28. Is a packet of digestive enzymes that destroy cellular wastes.






29. Most fossils of Hominids are from continents other than...






30. The process whereby cells build molecules and store energy (in the form of covalent chemical bonds).






31. 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.






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






33. Subsets below the kingdom level






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






35. A sex-linked recessive disorder carried on the x chromosome in which an individual cannot perceive certain colors.






36. Assumes that there are periods of stability during which little evolutionary change occurs - and that speciation can occur rapidly over a very short period of time.






37. Contains the chromosomes and is the site of reproduction through mitosis and meiosis.






38. The phylum of insects (bees).






39. Consists of undifferentiated cells capable of quick growth and specialization. It is responsible for elongation of the stem.






40. Refers to the birthrate of a population.






41. Fossilized burrows from multicellular organisms begin to appear in the geological record approximately 700 million years ago during the Precambrian period. These multicellular animals had only soft parts and could not be fossilized.






42. An opportunistic life strategy strategy. Lichens invading a bare rock area after a volcanic eruption is an example.
