1. Review Game Quiz 2 CP Biology Ms. Albu

2. Directions  Grab a whiteboard & marker  You will be given 30 seconds to chat (Quietly: don’t give YOUR answer away) with your group  Write down your final answer  Read answer to class  Each team with a CORRECT answer receives a POINT  Most points= winner

3. List the steps of the scientific method in order  Problem  Research/Discussion  Hypothesis  Experiment  Data  Conclusion

4. What are the 5 characteristics of life?  Made of cells  Obtain/Utilize Energy  Reproduce  Respond to stimulus  Growth and Development

5. Scientists test hypotheses by….  Doing experiments

6. Define Metabolism  All the chemical activities of an organism or cell

7. Describe the difference between growth and development To grow means to get bigger and to get bigger; more cells must be added. Development means to change into ADULT FORM

8. What is ATP?  The form of energy obtained from the breakdown of glucose in cellular respiration  Energy source for cells that is used in metabolism

9. Define Cellular Respiration  The process by which glucose is broken down to produce energy for the organism in the form of ATP molecules

10. Define Autotroph & Give an example (2 points)  converts sunlight energy into chemical energy through the process of photosynthesis  PRODUCER

11. Identify which happens in Animals, plants, or both: 1) Photosynthesis 2) Cellular Respiration

12. Define an independent and dependent variable  Independent “Cause”: What is changed, what is tested, the x-axis of the graph  Dependent “effect” What is measured, result of the experiment

13. GIVE 2 EXAMPLES OF HOMEOSTASIS  Temperature regulation  Blood pH regulation  Blood glucose regulation

14. Explain why Yeast is living [2 mins: 2 Points]

15. Name the 2 types of cellular respiration  Aerobic  Anaerobic

16. Ms. Albu mixes yeast with warm water, sugar (glucose) and observes bubbles. What is process is going on? This is proof for which characteristic of life  Cellular RESPIRATION  OBTAIN/UTILIZE ENERGY

17. Explain why Fire is living or non-living. 2 Mins

18. Explain evolution  HAPPENS OVER MANY GENERATIONS  Change in a species over time  ~99% of all organisms that were once living are now extinct  Either have adaptations to survive and reproduce or die off

19. Which type of cellular respiration requires OXYGEN  Aerobic Respiration

20. Why do scientists need a control group?  Keep 1 group constant as means of comparison  To see effect of variables tested

21. Define HOMEOSTASIS  Maintaining internal conditions  Organisms utilize a lot of energy to maintain homeostasis

22. A hypothesis has to be…..  measurable,  Testable  Plausible/educated guess  If____, then____

23. 3 points: What is the independent & dependent variable? What kind of visual representation is this?

24. MAKE A HYPOTHESIS  Does yeast metabolize sugar and produce a gas?  Hypothesis: IF____________, THEN_______________.

25. Put in order of increasing complexity: Tissue, molecules, organ, cell, organ system, organism Molecules Cell Tissue Organ Organ system Organism

26. Give TWO examples of an organism responding to the environment (stimulus)  Shivering  Animal distress calls  Change of coat color with season change  Birds migrating  Fight or flight (adrenaline)  Pupils dilate in lower light  Reflexes (hot stove)

27. Your blood pH is normally 7.4. Your body works to regulate that it is maintained at 7.4- this is an example of ____________? Homeostasis

28. What are the types of Asexual reproduction?  Binary Fisson  Budding

29. Define HETEROTROPH  ingest or eat other organisms in order to obtain chemical energy  Also known as consumers
