BIO 112 Exam 1 Practice Multiple
Choice Test comprehensive Questions
and Answers with Verified Solutions
Question 1:
Which of the following represents an idea that Darwin learned from the
writings of Thomas Malthus? Populations tend to increase at a faster rate
than their food supply normally allows. The environment is responsible for
natural selection. Earth changed over the years through a series of
catastrophic upheavals. Technological innovation in agricultural practices
will permit exponential growth of the human population into the
foreseeable future.
Answer:
Populations tend to increase at a faster rate than their food supply
normally allows.
Question 2:
The diagram shows an outcrop of sedimentary rock whose strata are
labeled A-D. If x indicates the fossils of two closely related species,
neither of which is extinct, then their remains may be found in how many
of these strata? one stratum two strata three strata four strata
Answer:
NOT three strata
, Question 3:
Examine the evolutionary tree. The horizontal axis of the cladogram
depicted below is a timeline that extends from 100,000 years ago to the
present; the vertical axis represents nothing in particular. The labeled
branch points on the tree (V-Z) represent various common ancestors.
Let's say that only since 50,000 years ago has there been enough
variation between the lineages depicted here to separate them into
distinct species, and only the tips of the lineages on this tree represent
distinct species. Which pair would probably have agreed with the
Answer:
Lamarck and Wallace
Question 4:
Examine the evolutionary tree. The horizontal axis of the cladogram
depicted below is a timeline that extends from 100,000 years ago to the
present; the vertical axis represents nothing in particular. The labeled
branch points on the tree (V-Z) represent various common ancestors.
Let's say that only since 50,000 years ago has there been enough
variation between the lineages depicted here to separate them into
distinct species, and only the tips of the lineages on this tree represent
distinct species. Which of the five common ancestors, labeled V—Z, has
been most successful in terms of the percent of its derived species that
are extant? V W X Z
Answer:
Z
