2. Scientific Method What term is used for the factor that is measuredin an experiment? Dependent variable

3. Scientific Method What is the purpose of the control group in an experiment? To serve as a comparison to the experimental group

4. Scientific Method Name two ways to make lab results more valid or more reliable. Test more subjects. Repeat the experiment.

5. Lab Skills Which objective allows you to see the larger field of view? Low power

6. Lab Skills Which microscope part regulates the amount of light? Diaphragm

7. Lab Skills Which objective shows the greater magnification? High power

8. Lab Skills What do indicators do?Give an example. Indicators are chemicals that change color to show the presence of a substance. Iodine turns blue-black to show the presence of starch.

9. Required Labs - Biodiversity What is gel electrophoresis?What does it show? Electrophoresis is a technique that uses electricity to separate fragments of DNA or protein based on size. It shows bands of DNA or proteins that indicate similarities between individuals.

10. Required Labs - Biodiversity What is chromatography?What does it show? Chromatography uses a solvent to separate molecules in a mixture. It shows a pattern of colors that may show related organisms.

11. Required Labs - Biodiversity What do similarities in physical structure or molecules indicate? Organisms may share a common ancestor.

12. Required Labs – Diffusion Across a Membrane Which molecules can diffuse through the model of the cell? Iodine and glucose diffuse because they are small enough. Starch is TOO BIG and CANNOT diffuse.

13. Required Labs – Diffusion Across a Membrane What solution will make an onion cell shrink? Explain. SALT solution makes the onion cell shrink because water LEAVES the cell.

14. Required Labs – Making Connections Name 3 body systems affected by exercise? What change occurs in each system? Circulatory – pulse rate increases to bring more nutrients and oxygen to muscles. Respiratory – breathing rate increases to exchange gases faster Excretory – sweating increases to get rid of extra heat

15. Required Labs – Beaks of Finches What are some examples of adaptations in the lab? The different beaks (represented by the different tools) are adapted for eating different seeds or other foods.

16. Characteristics of Living Things Name 2 raw materials plants need for photosynthesis. Carbon dioxide and water

17. Characteristics of Living Things Name 2 products of photosynthesis. Where is the energy stored? Glucose and oxygen Energy is stored in the glucose.

18. Characteristics of Living Things In which cell organelle does photosynthesis occur? Chloroplasts

19. Characteristics of Living Things Which organelle allows materials to pass in and out of the cell? Cell MEMBRANE

20. Characteristics of Living Things Which organelle controls all of the cell’s activities? Nucleus

21. Characteristics of Living Things What two human systems regulate the body’s activities? Nervous and Endocrine

22. Characteristics of Living Things What do producers do? Producers convert the sun’s energy into chemical bond energy in food (organic molecules)

23. Characteristics of Living Things Name 3 products of aerobic cellular respiration.Where is energy stored at the end? Carbon dioxide, water, and ATP. Energy is stored in ATP.

24. Characteristics of Living Things In which organelle does cellular respiration occur? Mitochondria

25. Characteristics of Living Things Which body system TRANSPORTS materials through the body? Give examples. Circulatory system carries: Oxygen from lungs to cells, Nutrients from small intestine to cells, Wastes from cells to kidneys

26. Characteristics of Living Things Which system eliminates metabolic wastes from the body? Excretory (or Urinary)

27. Characteristics of Living Things Which body system breaks down nutrients to a usable form? Digestive

28. Genetics Put in size order starting with the smallest: chromosome, nucleus, gene. smallest - gene chromosome largest - nucleus

29. Genetics What are the 2 matching pairs of bases in DNA? A-T and G-C

30. Genetics What term is used for any change in the genetic information? Mutation

31. Genetics Where in the cell in DNA replicated or transcribed? In the nucleus

32. Genetics Where in the cell does protein synthesis occur? In the ribosomes

33. Genetics What is the technology that produces recombinant DNA? Genetic engineering

34. Evolution Define Evolution. Evolution is a process of change that occur in a species over a period of time

35. Evolution Name 2 types of evidence that support theory of evolution. fossils similar molecules (like DNA and proteins) comparative anatomy (similar structure) comparative embryology (similar embryos)

36. Evolution What term did Darwin use to explain evolution? Natural selection

37. Evolution What term describes a body structure or behavior that helps an organism to survive in its habitat? Adaptation

38. Evolution Name 2 sources of variations. recombining of genes in meiosis of sexual reproduction mutations in gametes

39. Evolution What are the four major parts to Darwin’s theory of natural selection? organisms overproduce this causes competition some variations have an adaptive value because they give a survival advantage the survivors pass on their characteristics to their offspring and these adaptations increase in the population

40. Reproduction and Development What is the purpose of mitosis? For growth and repair and replacement of cells

41. Reproduction and Development What kind of cells are made as a result of mitosis? Mitosis produces diploid body cells.

42. Reproduction and Development What is the purpose of meiosis? Meiosis produces gametes for sexual reproduction.

43. Reproduction and Development What kind of cells are made as a result of meiosis? Meiosis produces haploid sex cells or gametes.

44. Reproduction and Development What cell is formed as a result of fertilization? A zygote

45. Reproduction and Development In humans, where does fertilization occur? In the oviduct

46. Reproduction and Development Name a male reproductive hormone and where it is made. Testosterone is made in the testes.
