Science and Life Flashcards
Biology is
the study of life
All the characteristics of life
Atom - molecules - cell - tissue - organ - organ system - organism - population - community - ecosystem - biosphere
Taxonomy is
the discipline of naming things based on a shared classification
Broadest category of classification
domain
the 3 domains
bacteria, archaea, and eukaraya (BAE)
smallest classification
genus / species
what does genus communicate
similarities between individual species
what does species communicate
very specific information
The 6 things all living things have in common
Organized and complex - grow/make more cells - reproduce/make new genetic combinations - maintains systems within thresholds (homeostasis) - respond to the environment - transform energy
the 2 different cell types
Prokaryotic and eukaryotic
which cell uses mitosis for cell division
eukaryotic cells
which cell uses binary fission for cell division
prokaryotic cells
Reproduction through eukaryotic cells is
the process of making genetically new combinations when producing new organisms
what is the name for the cell division used for reproduction
meiosis (then feralization to make the organism)
how does meiosis work
one cell makes four non-genetically identical cells called gamete cells (sperm and egg)
What is fertilization
the fusing of sperm and egg to make an offspring
reproduction through prokaryotic cells is
using conjunction pili to connect with another cell and swap genes (the fastest way of reproducing)
Homeostasis is
maintaining systems within those thresholds/limits (if the limits are crossed damage can happen including death)
photosynthesis formula is
(CO2 + H2O –> C6H12O6 + O2)
Autotroph is
self feeder
heterotroph must
consume others for energy
what is the process of breaking glucose to make ATP energy
Aerobic cell respiration
paradigm is
a shared set of conclusions
are viruses or prions living things. why or why not
no, both have characteristic of living things but not all
the scientific method is
a methodical way of answering questions
steps of the scientific method
observation - hypothesis or research questions - experiment - conclusion based on data - communication - repeat
the two types of conclusions are
correlation and causation
correlation conclusion
there’s a relationship between the ind. and dep. variables, relationship is strong, most common conclusion is science
causation conclusion
caused the dep. variable EVERY SINGLE TIME, rare conclusion is science
the difference between hypothesis and theory
hypothesis is a proposed explanation while a theory has been proven and accepted
