Cards in this deck (45)
- 15 characteristics of life1) consist of 1 or more cells
2) take in & use energy
3) sense & respond to environment
4) maintain homeostasis
5) reproduce & grow - 2cellorganized unit that can live & reproduce by itself using energy, raw materials, & instructions in DNA
-smallest unit that can be alive - 3primatesmammals that walk on 2 feet such as humans & apes
- 4vertebratesanimals with backbones
- 53 kingdoms/domains of lifeeukarya, bacteria, archaea
- 6eukarya kingdomanimals, plants, fungi, microscopic organisms (protists)
- 7mammalsvertebrates that have body hair
- 8closest primate relativeapes
- 9why are humans more complex?great manual dexterity, analytical abilities, complex social behavior, great verbal skills
- 10life's organization orderatoms-molecules-cells-tissues-organs-organ systems-organism-population-community-ecosystem-biosphere
- 11producersself-feeding organisms that secure energy from physical environment like plants
- 12primary consumersorganism that feeds on primary producers
- 13secondary consumerorganism that eats primary consumers
- 14tertiary consumersorganism that feeds on primary & secondary consumers
- 15quaternary consumerstop predators of environment; eats tertiary consumers
- 16humans are typically...secondary consumers
- 17energy flowsun - producers (some energy lost) - consumers - decomposers (some energy lost)
- 18energyone-way flow through organisms & cycling of materials
- 19scientific studies are...systematic
- 20steps of scientific method1) observe natural phenomenon
2) identify question/problem to explore
3) develop testable hypothesis
4) make specific prediction
5) test prediction - 21ecosystems are...webs of life and actions in part of web affect the whole
- 22examples of effects of human activitiesloss of biodiversity
climate change
acid rain - 23experimenttest carried out under conditions researcher can control
- 24variablefactor that can change with time or with different circumstances
- 25control groupdiffers from experimental group; doesn't change or receive IV
- 26sampling errordevelops when experimenter uses sample/subset of a population for experimental group that is not large enough to be representative of the whole
- 27science has to be...based on logic
- 28critically thinking1) evaluate source
2) evaluate content
(let credible evidence do convincing and question credentials/motives) - 29correlation2 things happened at same time
- 30causethe reason why something happens
- 31what to remember about cause and correlationcause doesn't equal correlation
- 32factverifiable info
- 33opinioninvolves subjective judgement
- 34critical thinking defan objective, evidence-based evaluation of info
- 35theoryexplanation of range of observations/events based on repeated testing of hypothesis
- 36a theory can be...modified or rejected
- 37science can't...explain meaning of life or why we all die
- 38science doesn't involve...value judgements
- 39homeostasisstate of chemical and physical stability inside the body
- 40negative feedback includes...sensors, integrating center/control, effectors, & response
- 41why more diseases in recent years?1) more people on planet
2) more people traveling
3) misuse/overuse of antibiotics - 42respiratory tract preventative measureshandwashing
cover mouth for sneeze/cough
disposal of used tissues
vaccination programs - 43digestive tract preventative measureshandwashing
good public sanitation
proper food storage, handling, cooking - 44blood preventative measuresavoid needle sharing
maintain pure public blood supplies
vaccination programs - 45skin preventative measureshandwashing
limit contact with infected items
