"The Science of Biology" Evolutionary Biology, BIOL152 CSU Chico

Biology the science of life
the 7 characteristics of a living thing cellular organisation, ordered complexity, sensitivity, growth, energy utilization, homeostasis, and evolutionary adaption
the heirarchial organisation of living systems atoms, molecule, macromolecule, organelle, cell, tissue, organ, organ system, organism, population, species, community, ecosystem, biosphere
the scientific method observation, question, potential hypothesis, experiment, revision, results
homeostasis organisms maintain relatively constant internal conditions that are different than their environment
atoms fundamental elements of matter
molecules atoms joined together in clusters
organelles tiny structures within a cell
tissue groups of similar cells act as one unit
organs body structures that perform specific functions
population a group of organisms of the same species living in the same place
species all populations of a certain type of organism
biological community all populations of different species living together in one place
ecosystem populations and their environment together
emergent properties interactions occuring at lower levels can produce novel properties
inductive reasoning take a general idea and apply it to something specific
hypothesis suggested explanation that accounts for observations
reductionism reducing a topic to its parts to understand the whole
artificial selection selecting the mates for animals in order to breed for certain traits
homologous structures same evolutionary origin, but now different structire and function
analogous structures similar functions but different evolutionary origins
Which of the following is not a property of life? a. Energy Utilization b. Movement c. Order d. Homeostasis b. movement
The process of inductive reasoning involves? a. the use of general principles to predict a specific result b. the generation of specific predictions based on a belief system c. the use of specific observations to make general principles c. The use of specific observations to make general principles
a hypothesis in biology is best described as? an explanation for an observation
