Chapter 1 Flashcards
What are the 5 characteristics of life?
Organization Energy use Maintenance of internal constancy Reproduction, growth, & development Evolution
What is the basic unit of life?
Cells
Explain emergent properties.
Quality that arises from components systems interactions (creates new, complex function). Emergent properties arise at each level of biological organization.
What is organization? Give an example.
Hierarchical pattern
Exp: atoms>molecules>cells>tissues
Name the three types of energy usage of organisms.
Producers
Consumers
Decomposers
Define homeostasis.
Process by which organism or cell maintains internal constancy
What are the two types of reproduction? And, what differentiates them?
Asexual-genetic info from one parent. Offspring is almost identical
Sexual-genetic makeup from both parents. New traits begin in offspring.
What is evolution?
Change in genetic makeup of a population over generations.
What is adaption?
Inherited characteristics/behavior that allows successful reproduction/survival in changing environment.
Explain natural selection.
Enhanced reproductive success of certain individuals from a population based on inherited characteristics.
What is taxonomy?
The biological science of naming and classifying organisms.
What are the 2 categories that classify an organism?
Species and genus
What are the 3 domains that organisms are categorized under?
Domain Eukarya
Domain Archaea
Domain Bacteria
Name the 12 stages of organization in order smallest to largest.
Atoms, molecules, organelles, cells, tissues, organs, organ systems, organism, population, community, ecosystem, biosphere.
What type of energy is lost when transferred?
Heat
