At the end of the paragraph
. . .Most Anglo-Americans, for instance, see the
extensive family obligations of Hispanics as a
burdensome arrangement that inhibits individual
freedom. Hispanics, in contrast, view the
isolated nuclear family of Anglo-Americans as a
lonely institution that cuts people off from the
love and assistance of their kin. This tendency
to view one's own cultural patterns as good and
right and those of others as strange or even
immoral is called ethnocentrism."

study guides to use as memory aids. Your final
step is to review your notes and study guides
until you feel confident about taking the test."

"All organisms must insure that their offspring
have a reasonable chance to survive and begin a
new generation. Plants, however, face special
challenges. Plants do not have nervous systems,
and they are not able to run away from predators
or pests. Because nearly all plants live in fixed
positions, they must also manage to find mates
without being able to move around. Therefore they
have evolved strategies for dealing with these
problems that are essentially passive. An
important part of such strategies is a
reproductive pattern enabling each individual to
produce large numbers of offspring."
(Levine and Miller, Biology, 1991)
