characteristics of life Flashcards
cells
made out of all living things, two main types: prokaryotic, eukaryotic
metabolism
the chemical reactions that store or release energy to carry out life processes
reproduction
to produce an offspring that is either genetically identical (asexual) to the parent or a mix of dna from two parents (sexual), they must produce to continue existing
organization
the level of parts from small to large that make organisms
response to stimuli
to get information and react to it in some physical or chemical ways, organisms respond to signals called stimulus
homeostasis
to maintain a constant internal environment when the outside environment changes, internal feedback loops help the body maintain homeostasis
universal genetic code
all living things have dna directions for inheritance and carry these molecules
growth and development
to go from a smaller form to a larger form by the addition of cells, all organisms grow
evolution
the change of a population over time through natural selection
