The way something looks, is the what it does.
Modified and designed
Environment (Genes being 6’4 but not enough food to be that tall)
Evolutionary Past (Humans on 2 legs) 4. Name and describe 7 levels of structural organization 1. Chemical Level a. Atoms/Molecules b. Body is composed of Carbon, Hydrogen, Oxygen, Nitrogen, Calcium 2. Organelles c. Sub Cellular Structure 3. Cellular Level d. Where life begins 4. Tissue Level e. A tissue a group of similar cells that work together to perform a function I.E. Skeletol Muscle Tissue All look the same but work together for movement f. 4 Types of Tissue i. Epithelial (skin) ii. Muscle Tissue (skeletal muscle) iii. Connective Tissue (most diversed, blood/bone) iv. Nervous Tissue (complex behavior like taking listening and taking notes) 5. Organ g. Has combination of tissues that has a specific shape that perform a specific function 6. Organ System h. Related organs with common function 7. Organism i. Us, Humans 5. What are 7 different charterisictic that describes life? a. Metabolism – total chemical reaction in body i. Catabolism – break down large molecules into smaller ones ii. Anabolism- build large molecules from smaller ones b. Responsiveness iii. Able to detect and respond to stimuli c. Movement iv. Cellular to organism d. Growth v. Increase in size, number of cells
