Biology 200 Exam 1 - Cleveland State
University Questions And Answers
/. What are the characteristics of living things? - Answer-order, evolutionary adaption,
response to the environment, reproduction, growth and development, energy
processing,regulation
/.Biosphere? - Answer-includes all living things on earth that supports life; divided into
what we call ecosystems
/.Communities? - Answer-living things in ecosystems, ex: all trees In a forest
/.Populations - Answer-all the living things of one species
/.Ecosystems - Answer-geographical regions that include living things in regions
according to the environment and climate; have diff characteristics like hot wet dry cold
etc, like the rainforest or desert
/.Organisms - Answer-very different depending on ecosystems; one individual: one oak
tree
/.Organs and Organ Systems - Answer-broken down into tissues; tissues broken down
into cells; cells are broken down into organelles (like ribosomes) and broken down into
molecules
/.are organelles and molecules living things? - Answer-no
/.Tissue - Answer-two or more cell types that work together to perform a given function
/.molecules - Answer-made up of atoms
/.where does life form? what stage? - Answer-between organelle to cell
/.what is the hierarchy? - Answer-steps where new properties emerge into populations
slowly that are not at the lower/previous level
/.proteins - Answer-big molecules, made up of amino acids. 2 proteins: microtubule (like
a track) and motor protein (walking)
/.Killer T cells - Answer-can detect bad cells by recognizing proteins on the surface of
the cell and will kill it if needed if there is toxins
, /.Theory - Answer-best guess of how world works, have witnessed many tests over
time, how we believe natural world works
ex: theory of evolution, cell theory
/.Hypothesis - Answer-a tentative explanation for an observation, must be testable and
falsifiable
/.logic in science - Answer-general principles (like cell theory) -> deductive (if-then) ->
specific instances ->inductive
general principles lead to testable hypothesis and use if-then knowledge which gets you
specific instances
/.living things cannot exist without ____ - Answer-H20, water
/.Living things - Answer-obey laws of physics and chemistry, composed of matter in the
form of atoms, molecules, and macromolecules
/.Matter - Answer-anything that has mass and occupies space, made up of atoms
(smallest units of elements)
/.Element - Answer-a substance that can not be broken down to any other substance by
ordinary chemical means
/.atomic number - Answer-same as # of protons,
/.subatomic particles - Answer-protons, neutrons, electrons
/.protons - Answer-positive charge, # defines element, atomic number
/.electrons - Answer-negative charge, moves around in nucleus in "clouds"
orbit nucleus and attracted to protons, essential to chemical bonding and important in
energy metabolism
/.neutrons - Answer-no charge, contributes mass, # may vary with element
/.atomic mass (atomic weight) - Answer-protons plus neutrons, measured in daltons
(proton = 1 dalton, neutron = 1 dalton)
/.isotopes - Answer-atoms with the same atomic number but different atomic mass;
have same chemical properties ( these ones can bond with each other)
- different number of neutrons
- different number of protons and electrons
