What are the 2 Mechanisms of Evolutionary Change? -CORRECT ANSWER 1. Vertical
descent with modification
2. Horizontal gene transfer
Taxonomy -CORRECT ANSWER Grouping of species based on common ancestry
3 Domains -CORRECT ANSWER 1. Bacteria
2. Archaebacteria
3. Eukarya
Bacteria -CORRECT ANSWER Domain of unicellular prokaryotes that have cell walls.
Archaea -CORRECT ANSWER Domain of unicellular prokaryotes that have cell walls.
Eukarya -CORRECT ANSWER Domain of all organisms whose cells have nuclei,
including protists, plants, fungi, and animals
What are the 4 Eukarya Kingdoms? -CORRECT ANSWER 1. Protists
2. Fungi
3. Plantae
4. Animalia
Energy -CORRECT ANSWER Capacity to cause change
Prokarya -CORRECT ANSWER Domain of all anucleated organisms with cell walls,
including archaea and bacteria.
Development -CORRECT ANSWER Change in characteristics of cells and / or certain
genes/signaling
,Gene -CORRECT ANSWER A segment of DNA that is involved in producing a protein.
We have 25,000 functional genes and over 3 billion nucleotides.
Transcription -CORRECT ANSWER The process whereby the DNA sequence in a gene
is copied into mRNA.
Translation -CORRECT ANSWER The process whereby genetic information coded in
messenger RNA directs the formation of a specific protein at a ribosome in the
cytoplasm.
Genome -CORRECT ANSWER The complete genetic makeup of an organism, carries
information to make its proteome
Proteome -CORRECT ANSWER The complete complement of proteins that a cell or
organism can make
Cell -CORRECT ANSWER The basic structural and functional unit of all organisms.
Energy Use -CORRECT ANSWER To maintain their internal order, ________ is
needed by organisms.
Irritability -CORRECT ANSWER An organism's ability to respond to environmental
stimuli. E.g., kingdom animalia has high ___________.
Cell Theory -CORRECT ANSWER All living organisms are composed of cells. They
may be unicellular or multicellular. The cell is the basic unit of life. Cells arise from pre-
existing cells.
Matter -CORRECT ANSWER Anything that has mass and occupies space.
Atom -CORRECT ANSWER The smallest unit of an element that retains the properties
of the element that cannot be broken down naturally
What are the 4 Properties of Life? -CORRECT ANSWER Organization of Life
Continuity of Life
Unity
Diversity
Organization of Life -CORRECT ANSWER Growth & development is possible through
the organization of life
Continuity of Life -CORRECT ANSWER Heredity is possible through the continuity of
life (DNA)
, Diversity -CORRECT ANSWER Many types of environments with diverse
organisms=speciation
Unity -CORRECT ANSWER Common traits rooted in biological evolution.
Homologous Organs -CORRECT ANSWER Organs or body parts that are similar in
structure and origin but have different uses in different animals
Analogous Organs -CORRECT ANSWER Same function different structure
Vertical Descent with Modification -CORRECT ANSWER Progression of changes in a
lineage; new species evolve from pre-existing species by the accumulation of mutations
that are selected for by natural selection.
Horizontal Gene Transfer -CORRECT ANSWER The transfer of genes between cells of
the same generation. E.g., penicillin resistant bacteria confers it's immunity to other
bacteria.
What is the Human Taxon? -CORRECT ANSWER eukarya, animalia, chordata-
vertebrata, mammalia, primates, haminidae, homo, sapiens
Science -CORRECT ANSWER The observation, identification, experimental
investigation, and theoretical explanation of natural phenomena.
Theory -CORRECT ANSWER Broad explanation of some aspect of the natural world
that is substantiated by a large body of evidence. Allows us to make many predictions.
Also can never be proved true
Deductive Reasoning -CORRECT ANSWER General principles are used to predict
specific results. E.g., the pecies of an organism can be deduced from its characteristics
Inductive Reasoning -CORRECT ANSWER Specific observations are used to construct
general scientific principles.
What are the 5 Steps of the Scientific Method? -CORRECT ANSWER A series of steps
followed to solve problems
1. Collect data
2. Form a hypothesis
3. Test the hypothesis
4. Analyze data
5. State conclusions
Cystic Fibrosis -CORRECT ANSWER Affects about 1 in every 3,500 Americans.
Characterized by thick mucus in the lungs.
Homozygous (need 2 bad copies).
