Bio powerpoints 1 Flashcards
What is biology
The study of living things, science of life
what are the 6 kingdoms of life
fungi, plants, animals, protists, bacteria, ancient bacteria
what qualifies something as living versus non living
complexity, movement, response to stimulation
5 properties of life
cellular organization, metabolism, homeostasis, growth/reproduction, heredity
organization of life
cellular, organismal, populational
higher order processes that are hallmarks of life are
emergent properties
(metabolism, consciousness)
5 biological themes
evolution, the flow of energy, cooperation, structure determines function, homeostasis
homeostasis is
a physiological condition of “steady-state”
symbiosis is
when two species live in direct contact
the mechanism for evolution is
natural selection
Scientific process is
observation, hypothesis, predictions, testing, controls, conclusion
theory is
different to scientists than the general public
science is limited to
organisms and processes that can be observed and measured
four theories that unify biology as a science
cell theory
gene theory
theory of heredity
theory of evolution
cell theory
all organisms are composed of at least one cell
gene theory
genetic information is in molecules of deoxyribonucleic acid (DNA)
theory of heredity
genes are passed down generations as discrete units
what theory of heredity gave rise to the field of genetics
Mendel’s
Theory of evolution- common ancestry
six kingdoms are grouped into 3 domains
who attributed evolution to natural selection
Charles darwin
three domains of life
bacteria
archaea
eukarya
which variable is Y axis
dependent
which variable is x axis
independent
