SET QUESTIONS WITH 100% RATED CORRECT ANSWERS
Table 1 summarizes selected characteristics of organisms from each of the three domains of life.
Which of the following sets of data provides evidence that best supports common ancestry for
organisms in all three domains? - (answers)Organisms in Bacteria, Archaea, and Eukarya each
have adenine, thymine, guanine, and cytosine bases forming their DNADNA.
The heterotroph hypothesis of the origin of life states that basic organic building blocks formed
from inorganic molecules under the primitive conditions present early in Earth's development.
These building blocks combined to form polymers, such as crude proteins. Dr. Sidney Fox
wished to add to the heterotroph hypothesis of the origin of life by synthesizing simple proteins
from a mixture of amino acids.

Which statement below best states an alternative hypothesis Fox could have used to frame his
？ of available energy and the absence of a significant quantity
research? - (answers)In the presence
of atmospheric O2O2 simple proteins will form spontaneously from a mixture of amino acids.
Iridium is an element that is rare on Earth but commonly found in meteorites. A scientist believes
that the first organic molecules may have come to Earth on meteorites 3.6 billion years ago.
Which of these would be an appropriate null hypothesis to test related to whether meteorites hit
the Earth 3.6 billion years ago? - (answers)There is no difference in iridium levels in sediments
that were deposited on Earth 3.6 billion years old, compared to recent sediments.
In addition to the ABO blood groups, humans have an MN blood type system in which the M
and N alleles are codominant to one another. These alleles code for glycoproteins that act as
antigens on the red blood cells. Scientists determined the frequencies of the M and N alleles in
five localized and stable human populations in the Philippines (Figure 1). Based on the data in
Figure 1, which of the following would most affect the allelic frequencies of the populations on
Isabela and Butuan? - (answers)Immigration of individuals from Metro Manila into the two
populations
Thoroughbred race horses are subject to intense artificial selection to produce faster-running
horses. The results of breeding programs can be seen in the change in winning times of the
Kentucky Derby from 1880 to the present, as shown in Figure 1. Which of the following best
explains the trend shown in Figure 1? - (answers)By 1940, most genetic variation for speed had
been lost from the gene pool.
