6 The Biosphere Made up of ALL the living things AND all the places they are found: LIVING THINGS PLACES Bacteria Deserts Protist Grasslands Fungus Saltwater Plants Freshwater Animals

7 The variety of life across the biosphere. Biodiversity generally increases from the Earth’s poles to the equator.

8 EQUATOR Earth’s Rainforest (Greatest variety and Highest population of living organisms)

9 Consistent warm temperatures Constant precipitation More species can survive in warm areas that offer a larger and more consistent food supply. Species: A particular type of living thing that can reproduce by interbreeding among themselves

10 __________ not only in size, but in development __________ essential for survival __________ smallest unit of life __________ breathing, eating, digestion, excretion __________ adapt and change with environment __________ to light, sound, temp, etc. “GROMER” GROWTH REPRODUCTION CELLS METABOLIZE EVOLVE RESPOND

11

12 Growth refers to an increase in some quantity over time. The quantity can be physical (e.g., growth in height) or abstract (e.g., a system becoming more complex, an organism becoming more mature).

13

14 Members of a species must have the ability to produce new individuals, (reproduce). Through reproduction, organisms pass on their ___________________, (DNA: Deoxyribonucleic Acid) Combining of _______ and __________; Combination of ______ from ___ parents ___________ from one parent divides into two cells. New cells have _____________ ______ as original parent genetic material sperm egg DNA2 One cell identical DNA

15 CELL ORGAN SYSTEM ORGANISM TISSUE

16 All living things are made up of one or more cells

17

18 All organisms need a source of __________________ for their life processes. The form of energy that all organisms use is ___________________________ _______________ ____________ ENERGY CHEMICAL ENERGY SUNLIGHT FOOD

19

20 Evolution is the ________________________________; (Change in the _____________ of a population of species.) Besides having stiff spines that stick out from their bodies and help protect them, these animals also have loose skin under those spines and powerful back muscles. Why? How are the mouths of pythons adapted to finding prey and swallowing large prey? CHANGE IN LIVING THINGS OVER TIME GENETIC MAKEUP

21

22 __________________ LIGHT All organisms must _______________ to their __________________ to __________________. REACT ENVIRONMENTSURVIVE TEMPERATURE TOUCH

23 Describe biodiversity in terms of species Describe the relationship between cells and organisms. What characteristics are shared by all living things? How does biodiversity depend on a species’ ability to reproduce? Cells are the smallest part of organisms. (They make up organisms) GROMER Growth, Reproduction, Cells, Metabolize, Evolve, Reproduction

24 Homeostasis Literal Meaning: “Same Status/Condition” Homeostasis is the maintenance of constant internal conditions in an organism. Examples of conditions that require homeostasis: TEMPERATURE BLOOD SUGARACIDITYHYDRATION LEVELS

25 Describe a biological system. Give an example of how structure is related to function in living things. Why is homeostasis essential for living things? What is the relationship between adaptation and natural selection? How are structure and function related to adaptation? How is the process of natural selection involved in evolution?

26 _________________________________________________ ___________________________________________________ STUDENTS DO NOT RETAIN THE INFORMATION PRESENTED / TAUGHT IN CLASS IF STUDENTS ATTACH SPECIFIC MEANING OR ASSOCIATIONS WITH TERMS, THEN THEY WILL LEARN THE INFORMATION HAVE STUDENTS COPY A LIST OF 10 WORDS LABELED “A” AND “B”. THE STUDENTS HAVE TO WRITE THE “A” WORDS TWO TIMES WHILE FOR THE ‘B’ WORDS THEY FIRST WRITE A WORD THAT THEY ASSOCIATE WITH THE TERM AND THEN WRITE THE WORD ITSELF ONCE. _____ TOTAL STUDENTS RECALLED ______ TOTAL WORDS: ______ ‘A’ WORDS AND _____ ‘B’ WORDS STUDENTS DO LEARN BETTER IF THEY MAKE ASSOCIATIONS AND OR CONNECTIONS TO NEW INFORMATION PRESENTED TO THEM

27 1.Control group: ___________________ or the ‘thing’ that does not change a. _________________________________________ 2. Variable: the “_______________________” group or the “thing” that changes a. _________________________________________ EXPERIMENTAL GROUP CONSTANT GROUP “A Words” Independent “B Words” Dependent “The outcome”. The outcome is dependent upon the independent variable. What ________------------------------------------

28 1.State the _______________ a. The process of ‘inquiry’ begins with ____________________, (using ones senses to study the world) 2.Create a ___________________(educated guess) a.A hypothesis is a ____________________________ for a scientific question b.Should be an ___________ / ___________ statement indicating the action(s) that will take place and the results that are anticipated 3. Test the ___________________ (experiment) 4.Evaluate ______________(results) a. Observations and tools can be used to gather and analyze data 5.Make a ____________________ a.Hypotheses can be__________________ or _______________ in the conclusion Experiments are always ______________. ___________________ are developed once experiments have been tested several times and end with the same _________________ PROBLEM HYPOTHESIS DATA CONCLUSION observations Proposed answer IF THEN acceptedrejected ONGOING THEORIES Conclusion

29 What role do hypotheses play in scientific inquiry? What is the difference between and independent variable and a dependent variable? How is the meaning of theory in science different from the everyday use of the term? How are hypotheses and theories related? Give examples of different ways in which observations are used in scientific inquiry.

42 10,000 new species are discovered each year. However, it is estimated that over 50,000 species become extinct every year That your body cells have specialized functions? Muscle cells: contract and relax Stomach cells: Secrete digestive enzymes Brain cells: interpret sensory information That the lining of your nose is actually a habitat for bacteria and fungus. This means the lining of your nose is part of the biosphere!

43 How do light microscopes differ from electron microscopes? Why is computer modeling used in biological studies? How does molecular genetics and to our understanding of genes?
