BIO 130 LATEST 2026 EXAM QUESTIONS AND ANSWERS
GUARANTEE A+
✔✔Cooperative Interaction - ✔✔Territorial choruses by male lions discourage intruders
and are likely to benefit all contributors.
✔✔Selfish Interaction - ✔✔Actor (Organism) benefits/recipient is harmed. Opposite of
Altruistic Interaction.
✔✔Altruistic Interaction - ✔✔Recipient befits/actor (Organism) is harmed. Opposite of
Selfish Interaction.
✔✔Spiteful Interaction - ✔✔Cost for the actor (organism) and a negative impact upon
the recipient.
✔✔Spiteful Interaction - ✔✔Infanticide is an example of this type of interaction
✔✔Kin Selection - ✔✔Natural selection that favors altruistic behaviors by enhancing
reproductive success of relatives.
✔✔Indirect Fitness - ✔✔derived from helping relatives produce more offspring than they
could produce on their own
✔✔Coefficient of Relatedness - ✔✔Probability that if two individuals share common
parent or ancestor, a particular gene present in one will be present in other.
✔✔Species - ✔✔A group of similar organisms that can breed and produce fertile
offspring.
✔✔Biological Species Concept - ✔✔Defines a species as members of populations that
actually or potentially interbreed in nature, not according to similarity of appearance.
Although appearance is helpful in identifying species, it does not define species.
✔✔Biological Species Concept - ✔✔Species are groups of actually or potentially
interbreeding natural populations, which are reproductively isolated from other such
groups
✔✔Biological Species Concept - ✔✔A species is a reproductive community of
populations (reproductively isolated from others) that occupies a specific niche in nature
✔✔Biological Species Concept - ✔✔Species are the members in aggregate of a group
of populations that breed or potentially interbreed with each other under natural
conditions
, ✔✔Evolutionary Species Concept - ✔✔A species is a lineage (an ancestral-descendant
sequence of populations) evolving separately from others and with its own unitary
evolutionary roles and tendencies
✔✔Evolutionary Species Concept - ✔✔A species is a single lineage of ancestor-
descendant populations which maintain its identity from other such lineages and which
has it own evolutionary tendencies and historical fate
✔✔Evolutionary Species Concept - ✔✔A species is a population or group of
populations that shares a common evolutionary fate through time
✔✔Ecological species concept - ✔✔A species is a set of organisms exploiting (or
adapted to) a single niche
✔✔Ecological species concept - ✔✔A species is either 1) a lineage which occupies an
adaptive zone minimally different from that of any other lineage in its range, and which
evolves separately from all lineages outside its range, or 2) a closely-related set of
lineages which occupy an adaptive zone minimally different from that of any other
lineage in their range and which evolve separately from all other lineages outside their
range
✔✔Ecological species concept - ✔✔A species is a lineage or a closely related set of
lineages, which occupies an adaptive zone minimally different from that of any other
lineage in its range and which evolves separately from all lineages outside its range
✔✔Morphological species Concept - ✔✔groups species according to physical/structural
similarities and ignores other differences such as DNA or inability to reproduce between
individuals. This concept stems from the study of the physical aspects of an organism
and their arrangement.
✔✔Allopatric Speciation - ✔✔The formation of a new species as a result of an ancestral
population's becoming isolated by a geographic barrier.
✔✔Allopatric Speciation - ✔✔
✔✔Sympatric Speciation - ✔✔The formation of a new species as a result of a genetic
change that produces a reproductive barrier between the changed population (mutants)
and the parent population. No geographic barrier is present.
✔✔Sympatric Speciation - ✔✔
✔✔Isolation by vicariance - ✔✔The physical splitting of a population into smaller,
isolated populations by a geographic barrier
