1. Which one of the following is a selective advantage of simple multicellularity
over single-celled
organisms?: Multicellularity helps organisms avoid predation.
2. Which one of the following organisms has coenocytic organization?: some
green algae
3. Why do mitochondria and chloroplasts have small genome?: They have
small genomes because over time, much of their nucleic acid has migrated to the
host cell
nucleus.
4. Some slime molds make structures called plasmodia which:: contain many
nuclei in one large cell.
5. Chloroplasts have outer and an inner membranes that separate the stroma
and thylakoids from the
cytoplasm. What is believed to be the origin of the outer membrane of the
chloroplast?: It is the remnant of the ancient host cell's plasma membrane following
endocytosis of the
cyanobacteria.
6. The peppered moth provides a well-known example of natural selection. The
lightcolored
form of the moth was predominant in England before the industrial revolution.
In
the mid-nineteenth century, a dark-colored form appeared. The difference is
produced by
a dominant allele of one gene. By about 1900, approximately 90% of the moths
around
industrial areas were dark colored, whereas light-colored moths were still
abundant
elsewhere. Apparently, birds could readily find the light moths against the
soot-darkened
background in industrial areas and therefore were eating more light moths.
Recently, use
of cleaner fuels has greatly reduced soot in the landscape, and the dark-col-
ored moths
have been disappearing. Should the two forms of moths be considered sepa-
rate species?: No
7. Three populations of crickets look very similar, but the males have courtship
songs that
sound different. What function would this difference in song likely serve if the
populations came in contact?: a prezygotic isolating mechanism

8. How are two different species most likely to evolve from one ancestral
species?: allopatrically, after the ancestral species has split into two populations
9. polytomy is a graphical depiction of what type of relationship between
groups?: The common ancestor node with no resolution among descendant
groups.
10. One reason we see relatively little genetic variation among human regional
populations
is that:: humans migrated out of Africa so recently that we haven't had enough time
for regional variation to accumulate
11. The term "n" refers to the size of a population, that is, the number
of individuals in that population. In general, in a sample of n
individuals, the frequency of an allele is: he number of occurrences of the allele
divided by twice the
number of individuals in the sample (2n).
12. If a population is not in Hardy-Weinberg equilibrium, we can
conclude that:: evolution has occurred because one of the assumptions of the
Hardy-Weinberg equilibrium has been violated.
13. The goldenrod gall fly lays its eggs on the terminal buds of
goldenrod plants. Larvae chew through the buds and into the stems,
where their saliva induces the plant to generate a gall (an outgrowth
of tissue). This gall then provides food and shelter for the
developing larva. The larvae are prey of both parasitoid wasps and
birds. Wasps selectively prey on larvae inside the smallest
galls while birds selectively prey on larvae inside the largest galls.
Goldenrod gall flies are therefore subject to: stabilizing selection.
14. You find that a wild population of antelope is not in HWE. From this
information alone, can you determine the mechanism of evolution
operating on the population?: no
15. Regarding the laboratory exercise this week, which Hominin had the
largest relative volume in its cranium?: Homo sapiens neanderthalensis
16. A college student walks down New York City's Fifth Avenue at 8:00 AM. She
is late for class so she
catches the bus for the last 2 miles of her commute. Did she have a larger
ecological footprint when she
was walking or when she was on the bus?: More information is needed about,
for example, the number of people on the bus and its fuel
source, to accurately determine her ecological footprint in both situations
17. Under the "business as usual" model of climate change, will temperatures
change uniformly across the
