AP BIO PRACTICE EXAM 3 EVALUATION
FULL SOLUTION UPDATED STUDY GUIDE
⩥ Resource partitioning.
Answer: The division of environmental resources by coexisting
species such that the niche of each species differs by one or
more significant factors from the niches of all coexisting species
⩥ Herbivory.
Answer: interaction in which one animal (the herbivore) feeds
on producers (such as plants)
⩥ Mutualism.
Answer: A relationship between two species in which both
species benefit
⩥ Competitive exclusion.
Answer: Strong competition can lead to local elimination of one
of the species.
⩥ Character displacement.
,Answer: The tendency for characteristics to be more divergent in
sympatric populations of two species than in allopatric
populations of the same two species.
⩥ Symbiosis.
Answer: A close relationship between two species that benefits
at least one of the species.
⩥ Commensalism.
Answer: A relationship between two organisms in which one
organism benefits and the other is unaffected
⩥ Ecological niche.
Answer: the sum of a species' use of the biotic and abiotic
resources in its environment
⩥ Predation.
Answer: An interaction in which one organism kills another for
food.
⩥ Parasitism.
,Answer: A relationship between two organisms of different
species where one benefits and the other is harmed
⩥ Facilitation.
Answer: An interaction in which one species has a positive
effect on the survival and reproduction of another species
without the intimate association of a symbiosis
⩥ Atom.
Answer: basic unit of matter
⩥ Electron.
Answer: a negatively charged subatomic particle
⩥ Neutron.
Answer: a small particle in the nucleus of the atom, with no
electrical charge
⩥ Proton.
Answer: a subatomic particle that has a positive charge and that
is found in the nucleus of an atom
, ⩥ Nucleus.
Answer: a part of the cell containing DNA and RNA and
responsible for growth and reproduction
⩥ Isotope.
Answer: atoms of the same element that have different numbers
of neutrons
⩥ Energy levels.
Answer: the possible energies that electrons in an atom can have
⩥ Electron shells.
Answer: an energy level of electrons at a characteristic average
distance from the nucleus of an atom
⩥ Orbitals.
Answer: regions around the nucleus in which given electron or
electron pair is likely to be found
⩥ Valence electrons.
