2. Ch.1 Introduction: The Scientific Study of Life

3.  What are these?  Flying foxes  What do they have to do with chapter 1?  Flying foxes are used as an example of organisms interacting with their environment  List 3 things you learned about this animal?  Carry pollen  Fly 25-30Km/hr  Not blind  Type of bat

4.  In one or two sentences explain what this picture means?  This is the levels of organization in an ecosystem  Which level is the largest?  Ecosystem  Name another organ and organ system found in most animals  Kidney/Urinary system  Heart/circulatory system  Lungs/respiratory system

5.  What have scientists learned from observing flying foxes with their babies?  They carry their babies when they are flying  What type of science is this called?  Discovery

6.  What do we call this type of science?  Hypothesis-driven  How is it different from discovery science?  It involves testing a hypothesis rather than just observing.  What do you think you would have to do after you test your hypothesis?  See the next slide

7.  What is the difference between inductive and deductive reasoning?  See the next slide

8.  Deductive reasoning starts with a theory and ends in confirmation or rejection of the theory  Inductive reasoning starts with an observation and leads to a theory

10.  How do we use both of these types of reasoning in science?  We make observations that lead to the formation of reasonable hypothesis which we can test.  What do you observe about the two animals in the bottom picture?  The fly looks like a spider when it flaps its wings.

12.  What does a control group mean?  These were not treated  Why did they dye the experimental group?  They covered the markings so it would not look like a spider  What did they find out?  Flies without markings got attacked more often

13.  What did scientists do in this experiment?  The transplanted wings.  Why were there 2 controls?  They wanted to show that transplanted wings still worked so they transplanted mimic wings onto mimic flies  What was the conclusion?  Mimic wings are not enough to prevent attack they need to know the waving behavior too. Houseflies with mimic wings were still attacked.

14.  What are the 3 domains?  Archea, bacteria and eukarya.  Domain bacteria on the top and archea on the bottom both have what type of cells?  Prokaryotes

15.  The top picture is in which domain and kingdom?  Domain eukarya, kingdom Plantae  The bottom picture is in which domain and kingdom?  Domain eukarya, kingdom Fungi

16.  The top picture is in which domain and kingdom?  Domain eukarya, kingdom protista  The bottom picture is in which domain and kingdom?  Domain eukarya, kingdom animalia

18.  The orchids in the top picture illustrate what major idea in biology?  Diversity  The molecule pictured is?  DNA  It represents unity of all living things

19.  What idea is being ilustrated in the picture?  Natural selection

21.  Can you tell what these are?  Sea horses  Why are they so hard to see?  Camouflage

22.  What does this picture represent?  Food web  How does CO 2 get incorporated?  Plants convert it to sugar  What is the function of a decomposer?  They eat dead material and break it down into molecules again.

23.  What is this bird doing?  Getting energy

24.  Does energy cycle through the environment?  No it is lost as heat  Do nutrients cycle?  Yes they are constantly broken down and put back together.
