Terms in this set (102)
Properties of living things Order, DNA, Reproduction, Growth & Development, Energy Processing,
Regulation/Homeostasis, Evolutionary Adaptation
Central Themes in Biology Emergent, Living things are organized, Organisms interact with their environments,
Life Requires energy transfer and transformation, Structure correlates with
function
The Cell Basic Unit of Life, Smallest unit that inhibits all properties of life,
What molecule has genes and is considered the DNA
molecule of inheritance in all living things?
Life is regulated by... Feedback mechanisms
Importance of feedback mechanism For increasing or decreasing the output of a particular molecule
Evolution Change of traits of a population over time
Taxonomy The classification and naming of living things
Biology Study of living things
Why is evolution a central theme in biology? It explains diversity and unity of life
What is the Linnaen classification of organisms? Hierarchical system where levels of classification are subsets of others
List of Linnaen groups from most general to most specific Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species
(Did King Philip Come Over For Good Soup)
Domains of living organisms Bacteria, Archaea, Eukarya
Kingdoms in domain eukarya Plants, Animals, Fungi, Protists
Who was the scientists who published "The Origin of Charles Darwin
Species" that explained evolution by natural selection?
Steps of Natural Selection 1. Population shows phenotypic variation
2. Variations are reliably heritable
3. Competition between variants for limited resources
4. Those with certain traits will survive/reproduce rather than those who struggled
to survive
5. Outcome: Population will show increase of individuals with traits that were able
to survive better
, Adaptation Trait used to survive and reproduce in given environment
Why is natural selection considered a "mechanism" of It works as a process
evolution?
Inductive Logic Goes from particular instances to a general premise; Conclusions are no usually
certain
Deductive Logic Goes from a general premise to particular instances
Scientific Method 1. Observe
2. Make a hypothesis
3. Make a prediction on what will happen if hypothesis is proved
4. Conduct experiment
5. Analyze your data
Independent Variable The factor of interest
Dependent Variables The outcome/response
Control Group Receives all conditions except the factor of interest
Comparative Groups Comparing levels of independent variable
What is the difference between a hypothesis and a A hypothesis is a tentative explanation for an observable phenomenon, a theory is
theory? a set of ideas that explain things broadly and is supported by lots of evidence
what are the roles of comparative and control groups in Comparative compares the results from two or more versions of the independent
an experiment? variable. Control groups is used to determine if the independent variable is the
cause of the results.
Matter Takes up space and has mass
What are the three states of matter? Solids, liquids, gases
Element Substances that can't be broken down by chemical reactions
What is the basic unit of matter? Elements
What are the four elements that make up ~96% of living Carbon, Hydrogen, Nitrogen, Oxygen ("CHNO")
things?
What is the difference between and element and an An element is a substance that can't be broken down by chemical reactions, an
atom? atom is the fundamental unit of an element.
What are the three subatomic particles that make up Nucleus, Shells, and Electrons
atoms?
Atomic Number The number of protons
