Answers
Cells are - -characteristic of prokaryotic and eukaryotic organisms
-Prokaryotes are classified as belonging to two different domains. What are the domains? -
-bacteria and archaea
-Which of these provides evidence of the common ancestry of all life? - -near universality
of the genetic code
-Which of the following is/are true of natural selection? - -It requires genetic variation,
results in descent with modification and involves differential reproductive success
-Charles Darwin proposed a mechanism for descent with modification that stated that
organisms of a particular species are adapted to their environment when they possess - -
heritable traits that enhance their survival and reproductive success in the local
environment
-The best experimental design - -includes a large sample size and a control, and alters only
one condition between the controls and the experimental condition
-Which of the following are qualities of any good scientific hypothesis?
I. It is testable
II. It is falsifiable
III. It produces quantitative data
IV. It produces results that can be replicated - -I. It is testable
II. It is falsifiable
-How does a scientific theory differ from a scientific hypothesis? - -Theories are usually an
explanation for a more general phenomenon; Hypothesis typically address more scientific
issues.
-Which of these is an example of inductive reasoning? - -Hundreds of individuals of a
species have been observed and all are photosynthetic therefore, the species is
photosynthetic
-Why is scientific topic best discussed by people of varying points of view? from different
disciplines and representing diverse cultures? - -Robust and critical discussion between
diverse groups improves scientific thinking
-About twenty five of the ninety two elements are known to be essential to life. Which four
of these twenty five elements make up ninety six percent of living matter? - -Carbon,
Hydrogen, Nitrogen, Oxygen
