Notes-Lesson+2

Video 1: Important themes of bio: -science -technology -society

-evolution -structure-function relationship -science as a process

The deer population can cause serious problems: -land scapping -traffic accidents -human illnesses (Lyme disease)
 * public & economic consequences

Technology: -is the application of scientific discoveries to solve problems and meet human needs

Video 2:
 * biology: scientific study of life & living organisms
 * evolution: gradual process by which something changes into a different & usually more complex form

-myoglobin: oxygen in muscle -hemoglobin: oxygen in blood (both made of 2 chains: alpha & beta)

Bacteria: -amibas: complex, single celled -rodafers: multi-cellular, primitive organ systems (both microscopic)


 * ecosystem: all organisms in an area together with physical environment they enhabit
 * biological community: collection of organisms whose members interact with one another

Organization of Life: -ecosystem -community -individual -organ system -organ -tissue -cell -molecule

Video 3:
 * biology is problem solving process, not collection of facts

Scientific Method: -state problem -refine/redefine problem -hypothesis -make observations -develop theory -test hypothesis in controlled experiment


 * correlation: statistical comparison of 2 variables
 * high correlation: strong relationship between 2 variables
 * theory: tested explanation of facts, observations, & natural phenomena
 * controlled scientific experiment: experiment where all factors are the same between 2 test situations, except 4 the single experimental variable
 * hypothesis: tentative untested explanation of a scientific issue
 * causation: act of causing something to happen

Video 4: Lyme disease: -it took medical doctors, epidemeologists, wildlife biologists, antimologists, & micro biologists 2 figure out what causes disease

Prevent disease: -pesticides/insect repellents -antibiotics -vaccines

Video 5: THEME TABLE

QUIZ:

1.) What are the 4 most important themes in biology?
 * science/technology/society, evolution, structure-function relationship, science as a process

2.) Out of the 8 things in the organization of life, name 4.
 * ecosystem, community, individual, organ system, organ, tissue, cell, molecule

3.) What are all the steps to the scientific method?
 * state the problem, refine/redefine the problem, hypothesis, make observations, develop theory, test hypothesis in controlled experiment, continue to test it

4.) Can you treat/prevent Lyme disease? If so, how?
 * yes, with pesticides, antibiotics, vaccines

5.) What's an ecosystem?
 * all organisms in an area together with physical environment they enhabit

6.) What's a biological community?
 * collection of organisms whose members interact with one another

7.) What public and economic issues can deer cause?
 * land scaping, traffic accidents, human illnesses

8.) Name the 2 types of microscopic bacteria that video 2 talked about.
 * amibas, vodafers

What is science not?
 * extra credit
