4. Chapter 1 Notes Section 1.1 What is Biology?

5. I. The Science of Biology 1. What is the definition of Biology? ____________________________________ 2. The key aspect is simply learning about the different types of living things around you. A. Biologists study ____________________ 1. Living things do not exist in isolation, they are all functioning parts in the balance in nature. The study of life the interactions of life

6. II. Characteristics of Living Things A. An organism is anything that B.Characteristics of living things: 1._____________________________________ What are some examples of organization in organisms? ___________________________________________ possesses all the characteristics of life Have an orderly structure we are composed of cells, all of which contain DNA, which is builds tissue, etc.

7. 1. Have an Orderly Structure Doesn’t this look organized?

8. III. Characteristics of Living Things Continued….. 2. _________________________________________ 1.Living things are able to reproduce 2.Reproduction is not essential for the survival of an individual organism, but it is essential for _______________________________________ 3.Species= _______________________________________ _______________________________________ Produce Offspring Continuation of species a group of organisms that can interbreed and produce fertile offspring.

9. 2. Produce Offspring

10. III. Characteristics of Living Things Continued….. 3.___________ and _____________ 1.___________ = an increase in the amount of __________ __________and the formation of ______ ____________. Development – all the changes that take place during the lifetime of an organism. 4.__________________________________ 1.Organisms must be able to respond to stimuli in their environment. 2.The regulation of an organism’s environment to maintain conditions suitable for its survival is called _______________________. Grow Develop Growth Living material New structures Adjust to changes in the environment homeostasis

11. Grow and Develop

12. Adjust to Changes in Environment – an organisms surroundings Adaptation-organisms response to its environment Stimulus –anything that causes an organism to react Response – reaction to a stimulus Homeostasis- maintaining conditions suitable for survival Evolution- gradual change in a species over time

19. I. Kinds of Information C._________ Information A.This is ______________ data- that is, written descriptions of what scientists observe. B.This data is useful because _______________ _____________________________________ Qualitative Observational some phenomena aren’t easily expressed as numbers

20. I. Observing and Hypothesizing B.Experimenting A.What is a Controlled experiment? A.(most experiments involve 2 groups) B.The _____________ ____________= the part of the experiment that is the standard against which results are compared. (nothing changes) C.The ___________ ____________= the test group that receives experimental treatment (something has changed) Control group Experimental group

21. I. Observing and Hypothesizing B. Designing the Experiment a.________________ variable= the condition in the experiment that is tested b._____________ variable = the condition that results from changes in the independent variable. Independent dependent REMEMBER: DRY MIX Dry = dependent, responding, y axis Mix = manipulated, independent, x axis DRY MIX
