9/3 ATB  What type of cells fight infection?  Today: Discuss the characteristics of life Scavenger hunt due! First Quiz  Monday?

The basic unit of life is the cell

What is the difference between living and nonliving?  Two important terms: Biotic - living parts of the environment Abiotic –  nonliving parts of the environment  Abiotic Examples:

What are the characteristics of life?  Get in a group with people around you and try to brain storm as some ways to characterize living things (to differentiate them from non-living)

7 Characteristics of Life  Life is ORGANIZED (cell organization)  Life responds to STIMULI (responsiveness)  Living things maintain HOMEOSTASIS  Living things have a METABOLISM  Living things GROW and DEVELOP  Living things REPRODUCE (using DNA, passing on genes)  Living things EVOLVE

9/4 ATB  What is an abiotic factor? Give an example. Today:  Grade sheet  Pulse activity  Test – Next week

9/5 ATB  Why is a control important to an experiment?  Today: Biology CDT’s (B103 – MONDAY!!) ONLINE BOOK INFO!!  Login: biologyf208a  Password: (same as before) Continue pulse activity Online book scavenger hunt Test – Next Thursday

Characteristics of Life  A  Life is ORGANIZE (cell organization)  Organization of living things  Organism  Organ System  Organ  Tissue  Cell  Organelle  Biological Molecules  Atoms  What are some biological molecules? Proteins Lipids Carbohydrates Nucleic acids

9/9 ATB  Give one example of stimuli your body responds to.  Today: Finish CDT’s (if you haven’t already) Finish you online book scavenger hunt Homework  Book Assignment: Page ALL Rest of the week:  Wednesday – Finish the chapter  Thursday – Review for test  Friday – Test!

9/10 ATB  Name one biological molecule  Today: Finish the notes Homework due! (p25 #1-3all) Also, turn in book scavenger hunt if you didn’t already Get your study guides for test Test – Friday? (only if we finished the notes today) Periods 1, 3 & 9 – to Periods 6 & 7 -- to

 B  Life responds to STIMULI Examples:  C  Organisms maintain HOMEOSTASIS This is the maintenance of stable internal conditions EX:  Temperature, levels of water, nutrient uptake

 D  Energy Use or METABOLISM This is defined as processes that take in and transform energy from the environment Examples:  E  GROWTH and DEVELOPMENT Life grows and then changes (matures)  F  REPRODUCTION Passing of genes to offspring Sexual –  DNA from two organisms Asexual –  Organism produces exact copy of itself

 G  Life Changes over time (Evolution) Organisms evolve because of traits / adaptations which made them more successful at surviving and reproducting Adaptation –  Trait that improves an organisms chance of survival (Homer Evolution)

9/11 ATB  What are adaptations?  Today: Finish the chapter Get your study guide for the test Friday  Review for the test / work on study guide Tuesday  TEST! (bring a pencil!)

Characteristics of life review:  What does it mean if an organism is maintain it’s homeostasis?  What are two types of reproduction? _____________________ and __________________  What is it called when a population changes over time?  Give an example of an adaptation that makes humans be successful  What are the two main drives of all organisms  What is metabolism?  Give an example of a stimuli that you respond to.  Give an example of a stimuli that any may have to respond to.  Does an organism have to move to be considered alive?

Book Assignment  ASSIGNMENT – Section 1.3 Assessment  Page 25 #1-3

 Domain Bacteria  Domain Archea  Domain Eukarya -- No Nucleus, unicellular, prokaryotic Nucleus, mostly multicellular, eukaryotic (you)

 Bacteria – single celled – few organelles (prokaryotic)  Archea – single celled – few organelles – “extromophiles” (live in harsh environments)  Protists* –simple organization (usually single celled) - eukaryotic Examples – amoeba, algae etc.)

Kingdoms of Life  Plants - eukaryotic, mostly multicellular  Fungi - eukaryotic, mostly multicellular  Animals - eukaryotic, mostly multicellular

The Big Ideas in Biology  What do these mean?  Cellular Basis of Life  Living things are made of cells (single or multicellular)  Information and Heredity Living things are based off information in the genetic code This code is found in your DNA  Matter and Energy Living things require matter that provide energy and the nutrients needed to survive

The Big Ideas in Biology  What do these mean?  Growth, Development and Reproduction All living things must reproduce, grow and develop  Homeostasis Living things control their internal environment  Evolution Living things change  Structure and Function Living things have specific body parts that provide specific functions (eyes, legs, etc) 

The Big Ideas in Biology  What do these mean?  Unity and Diversity of Life Living things are very different, but at the molecule level the same (proteins, lipids, nucleic acids, carbohydrates)  Interdependence in Nature Biosphere – living planet Organisms are linked to biotic and abiotic factors  Science as a way of knowing. Use of scientific method to explain observations

 QUIZ BONUS: What does anatomy study?

The End

Scientific Method == Review  What do we use science for? Helps explain the world around us  How does this work? Usually starts with a question… …Why do things fall? How do plants grow? Why do leaves change color in the fall? What do barnacles eat?  This usually leads to a prediction and your hypothesis (sometimes in the “if-then” format) IF stuff falls then it is because the atmosphere is pushing down on them  Hypothesis - Proposed explanation for a phenomenon

Scientific Method (con’t)  Next, you want to test your hypothesis  Designing your Experiment Control Group–  setup that stays the same in the experiment Experimental Group –  setup that is changed in the experiment Independent Variable –  factor that you are testing Dependant Variable –  or responding variable (changes because of the independent variable)

 Biosphere – planet that sustains life  Ecosystem – communities of living organisms and their non- living environment Biotic = livingabiotic = non-living  Evolution – changing of a population over time

 Natural Selection – traits that are beneficial are more likely to be passed to offspring - “survival of the fittest”  Adaptations – Traits that improve organisms ability to survive and reproduce  Fitness – An organisms contribution to genes to the next generation

 Grey mice… …have better camouflage… Meaning they get eaten less… Meaning they pass on their grey genes to the next generation… Which means a higher fitness

 Describe how natural selection works.

 Create your own hypothesis explaining how giraffes evolved long necks, assuming their ancestors were shorter. What evolutionary pressure caused the longer necks? (Why did it happen?)  Giraffe fight!!! 
