Quiz Questions For Exam 3
Two groups of organisms that differ from one another in one or more characteristics and do not hybridize extensively if they occur together in nature are considered to be different
species
You see a sign on a door that reads "Homologous Structures Inside." You go in and find
structures of animals that have difference appearances and functions but seem to have evolved from the same body part in a common ancestor.
In the southeastern U.S., two species of wild lettuce (Lactuca) do not usually form hybrids, because they bloom at different seasons. The means of isolation appears to be
temporal
Protists are classified into a single kingdom because of which of the following features?
they are eukaryotes, but not fungi, plants or animals
Which of the following is not true about prokaryotes?
they contain organelles
The tropical diseases such as African sleeping sickness, Chaga's disease, and leishmaniasis are caused by
trypanosomes
A friend is trying to understand the concept of convergent evolution. Which one of the following statements best describes this concept?
Convergent evolution occurs when two species living in different areas evolve similarities through natural selection acting on those characteristics.
From a large population of lizards on the mainland, a small number of individuals arrives on a nearby island in the hold of a ship. Generations later, the island population of lizards has a different pattern of spots than those on the mainland, though it does not affect their survival. This is an example of
Genetic drift through the founder effect
The biological species concept requires that members of the same species
Mate in nature and produce fertile offspring

Plasmodium

The type of speciation that geographically isolates populations and results in the divergence of distinct species is called ____________ speciation.
allopatric
The wings of birds and butterflies are examples of structures that resemble each other and have similar function, but are the result of parallel evolution in separate lineages. These structures are called
analogous structures
Prokaryotes undergo a process that produces cells that are identical. This process is called
binary fission
In which of the following characteristics, prokaryotes and eukaryotes are similar?

One characteristic of evolution is that
it occurs in a branching pattern with no real goal
Archaea differ from Bacteria in all of the following except
lack of organelles
The shape of the beaks of Darwin's finches, industrial melanism, and antibiotic resistance are often cited as examples of the process of _______________ leading to evolutionary change.

nucleic acids as the hereditary material
The prokaryotic DNA is located in the
nucleoid region
The production of new species through polyploidy is especially important in
plants
The isolating mechanism that prevents hybridization between horses and donkeys is
postzygotic
Natural selection promotes speciation by all of the following except
promoting polyploidy
amoebas move place to place by means of their
pseudopods
