BIOLOGY 101 EXAM 4 QUESTIONS AND ANSWERS
Which experience made Charles Lyell realize that the Earth was millions of years old - CORRECT
ANSWER✅✅The volcanoes which had been erupting throughout history indicated that Earth was
millions of years old
Which of the following is a true statement about Charles Darwin - CORRECT ANSWER✅✅Charles
Darwin proposed natural selection as the mechanism of evolution.
Which of the following is a true statement about Alfred Russel Wallace - CORRECT ANSWER✅✅He
became known as the father of biogeography
-some argue that Alfred should be given primary credit over Darwin for discovering the theory of
evolution by means of natural selection
-he developed a theory of evolution by means of natural selection.
natural selection - CORRECT ANSWER✅✅A process in which individuals that have certain inherited
traits tend to survive and reproduce at higher rates than other individuals because of those traits.
Fossils are most likely to be found in - CORRECT ANSWER✅✅sedimentary rock
Animals that possess homologous structures - CORRECT ANSWER✅✅Have common ancestry, evolved
from the same ancestor
The approach to evolution that involves the study of structures during organismal development is
known as the study of - CORRECT ANSWER✅✅Developmental biology?
The similarity of early fish, frog, bird, and human embryos is evidence for - CORRECT
ANSWER✅✅Common ancestry
Evidence from molecular biology supports the theory of evolution by showing that - CORRECT
ANSWER✅✅Closely related organisms have more similar DNA and proteins
, In natural selection. Determines which phenotypes are successful - CORRECT ANSWER✅✅Current
conditions in the local environment
changes in allele frequencies and large-scale evolutionary changes in organisms are really the same
thing in terms of the underlined processes. The differences in the timescale during which changes occur,
with large-scale changes taking a lot longer, and the number of mutations occurring during that time.
True or false - CORRECT ANSWER✅✅False?
Assume there are two varieties of mice living on an island, one was brown and one with grey fur. They
are prey for Hawks on the islands. Which of the following is predicted by natural selection. - CORRECT
ANSWER✅✅because Brown mice blend better with the ground and gray mice blend with the rocks,
these are the ones that will be missed by the Hawks and the mouse distribution will tend to indicate this
which of the following statements most closely agrees with the theory of evolution by means of natural
selection as put forth by Darwin and Wallace - CORRECT ANSWER✅✅Organisms better adapted to their
immediate environment are most likely to survive and reproduce
"natural selection" and "evolution" are terms that are sometimes confused, even by freshman biology
students. What is the relation between natural selection and evolution? - CORRECT
ANSWER✅✅Natural selection is one of several mechanisms of evolution.
When they were first sold, aerosol insecticides were highly effective in killing flies and mosquitoes. Now,
several decades later, a much smaller proportion of these insects die when sprayed. The reason fewer
insects die when they are sprayed is that _____. - CORRECT ANSWER✅✅Many mosquitoes today are
descendants of mosquitoes with insecticide-resistant characteristics.
Which of the following is a population? - CORRECT ANSWER✅✅a result of natural selection, a group of
people of the same species living in the same place at the same time that can change over generations.
-the smallest biological unit that can evolve.
The smallest unit of evolution is - CORRECT ANSWER✅✅a population
What did we call the change in relative frequencies of alleles in a population over several generations? -
CORRECT ANSWER✅✅Microevolution
