lesson 2 - life Flashcards
what are the properties of living organisms?
movement, energy processing, regulation, adaption, reproduction, order, response to stimuli, growth and development
what is reductionism?
strategy of simplifying complex systems by studying smaller components
e.g., focusing on the heart instead of the whole body
what is macroevolution?
large-scale changes above the species level
what is microevolution?
small-scale changes in genetic composition within a population across generations
what are the three domains of life?
bacteria, archaea, eukarya
what is the structure of bacteria?
single-celled, no nucleus
true or false - archaea is single celled, no nucleus or mitochondria
true
what is the structure of eukarya?
more complex, with a nucleus
movement
living organism can move in some way
energy processing
the living organism is able to take in energy from food, sunlight, or chemicals
maintain the right body temperature or water balance, even when the environment changes
regulation (homeostasis)
adaptation
organisms change to better survive in their environment (animals grow thicker fur in colder climates)
living things can make more of their kind, either by having babies (animals) or producing seed (plants)
reproduction
order
living organism that has structures, like cells, tissues, and organs, which work together in a specific way to keep them alive
response to stimuli
living organism react to their surroundings
growth and development
ex: a seed grows into a tree or a baby grows into an adult
is evolution a hypothesis, theory or a law?
theory because it is supported by evidence
