EXAM Q’S AND A’S
evolution - answer- the process of change that has transformed life on Earth from its
earliest beginnings to the diversity of organisms living today
biology - answer- the scientific study of life
emergent properties - answer- novel properties that emerge that were not present
beforehand. These properties are due to the arrangement and interactions of parts
as complexity increases
system - answer- a combination of components that function together
systems biology - answer- an approach that attempts to model the dynamic behavior
of whole biological systems based on a study of the interactions among the system's
parts
biosphere - answer- consists of all life on Earth and all the places where life exist
ecosystems - answer- consists of all the living things in a particular area, along with
all the nonliving components of the environment with which life interacts
communities - answer- the entire array of organisms inhabiting a particular
ecosystem
population - answer- consists of all the individuals of a species living within the
bounds of a specified area
organisms - answer- individual living things
organs - answer- body parts that carry out particular functions in a body
organ systems - answer- a team of organs that cooperate in a larger function
tissues - answer- a group of cells that work together, performing a specialized
function
cells - answer- life's fundamental unit of structure and function
organelles - answer- the various functional components present in cells
molecules - answer- a chemical structure consisting of two or more small chemical
units called atoms
, eukaryotic cell - answer- subdivided by internal membranes into various membrane-
enclosed organelles. The largest organelle is the nucleus which contains the cell's
DNA
prokaryotic cell - answer- DNA is not separated from the rest of the cell by enclosure
in a membrane-bounded nucleus
deoxyribonucleic acid - answer- DNA
genes - answer- the units of inheritance that transmit information from parents to
offspring
gene expression - answer- the entire process by which the information in a gene
directs the production of a cellular product
genome - answer- the entire "library" of genetic instructions that an organism inherits
genomics - answer- studying whole sets of genes of a species as well as comparing
genomes between species
bioinformatics - answer- the use of computational tools to store, organize, and
analyze the huge volume of data that result from high-throughput methods
negative feedback - answer- the most common form of regulation of living systems in
which accumulation of an end product of a process slows that process
positive feedback - answer- an end product speeds up its own production
natural selection - answer- the natural environment "selects" for the propagation of
certain traits among naturally occurring variant traits in the population
science - answer- the use of evidence to construct testable explanations and
predictions of natural phenomena, as well as the knowledge generated through this
process
Observation, Generalization/Model, Predictive Statements/Hypotheses, Tests,
Repeat - answer- What is the scientific method in order?
inquiry - answer- a search for information an explanation, often focusing on specific
questions
data - answer- recorded observations
inductive reasoning - answer- a type of logic that is brought about by collecting and
analyzing observations
hypothesis - answer- a tentative answer to a well-framed question
