Read the following scenario to answer the following questions.
An abundant and continual supply of ATP is necessary for all living cells. Active
muscle cells require an extraordinary amount of ATP to permit strenuous exercise for
prolonged periods. Toxins, reduced blood flow, and a compromised respiratory system
can interfere with the transport of oxygen to active cells. A runner in a marathon faces
multiple obstacles to continue to produce sufficient ATP to remain competitive.

Please use the following information to answer the following question(s).
The collared lizard is a species found in the Desert Southwest. Male collared lizards
show considerable color variation, ranging from brightly colored to a very dull pattern.
Your goal is to determine the function, if any, of male color patterns in collared lizards,
using the scientific method. Your tentative explanation is that male color plays a role in
attracting females for mating purposes. You predict that females will preferentially
choose brightly colored males over dull-colored ones. To test your prediction, you
observed the interactions of female collared lizards with their male counterparts. You
selected males that were the same age and size, and that differed only in their coloration
pattern. You placed equal numbers of the two types of male lizards, bright and dull, in
aquariums, along with one female lizard per aquarium. Out of 350 aquariums observed,
the female chose to mate with the brightly colored male 277 times, and the dull-colored
male 70 times. In three instances, the females did not mate with either type.
Create a bar graph of your data, plotting the type of male (dull or brightly colored) on
the x-axis. On the y-axis, plot the frequency with which each type of male was chosen
by females. Using this graph, answer the following questions.
“Male collared lizards show considerable color variation.” This is a(n) ________.
A) hypothesis
B) conclusion
C) observation
D) result
Bermudagrass is a plant that is commonly used on golf courses. It has a fibrous root
system, and its leaf veins are parallel. Because it is mowed on a regular basis in golf
courses, it spreads via horizontal stems that root at the nodes, rather than by seed. It can
live for many years. What is the best classification for bermudagrass on a golf course?
A) It is a perennial monocot that reproduces asexually.
B) It is an annual eudicot that reproduces asexually.
C) It is a perennial eudicot that reproduces sexually.
D) It is an annual monocot that reproduces sexually.
