24. Martin keeps a worm bin in his basement because they need cooler temperatures to survive. He feeds them about
1 pound of kitchen scraps each week. One summer the temperatures rise above the optimal temperature for the

temperatures to rise above 85°F for 2 days in a row. Surprisingly, Martin noticed that only a small portion of the
worm colony died. What is the best explanation for this?
A. After the first summer a new species of worm evolved.
B. The worms sensed that the temperature was going to be hot in the future and adapted.
C. The worms learned how to tolerate higher temperatures.
D. The worms surviving the first year had a higher heat tolerance and passed this trait to their offspring.
E. Worms are insensitive to heat changes.
25. Which of the following terms is not correctly matched with a correct example?

38. Populations of amphibians, including frogs and toads, have been plagued by disease and high rates of deformity.
A recent study investigated whether problems among the populations have arisen due to poisons from chemicals
associated with agriculture. Biologists from the University of Florida collected local adult cane toads (
Bufo marinus)
from more than 20 different locations. Toads were collected from areas close to agriculture; both large-scale and
small-scale farms as well as from suburbs. At collection sites where 50-97% of the adjacent land was farmed,
males showed high levels of feminization. Feminized male toads were similar in color to females and had lower
levels of testosterone and often also deformed gonads. These changes can lead to sterile males or changes in
behavior that prevent mating from occurring. Which of the following statements would be considered a hypothesis
for this study?
A. Amphibian populations are facing problems due to agricultural chemicals.
B. Toxins are causing diseases and deformities within many amphibian populations.
C. Toads collected from suburbs had fewer deformities compared to toads collected from agricultural areas.

deformity. A recent study investigated whether problems among the populations have arisen due to poisons
from chemicals associated with agriculture. Biologists from the University of Florida collected local adult
cane toads (
Bufo marinus) from more than 20 different locations. Toads were collected from areas close to
agriculture; both large-scale and small-scale farms as well as from suburbs. At collection sites where 50-97%
of the adjacent land was farmed, males showed high levels of feminization. Feminized male toads were similar
in color to females and had lower levels of testosterone and often also deformed gonads. These changes
can lead to sterile males or changes in behavior that prevent mating from occurring. Which of the following
statements would be considered a hypothesis for this study?
A. Amphibian populations are facing problems due to agricultural chemicals.
B. Toxins are causing diseases and deformities within many amphibian populations.
C. Toads collected from suburbs had fewer deformities compared to toads collected from agricultural areas.

Chapter 2 The Chemical Basis of Life Key
Multiple Choice Questions
1. Which of the following is not one of the most common elements in living things?
A. carbon
B. oxygen
C. hydrogen
D. iron
E. nitrogen
Six elements of matter make up the majority of body weight of most organisms. There presence and properties
are essential to the uniqueness of living things.
Bloom's Level: 1. Remember
Learning Outcome: 02.01.01 Distinguish among the types, location, and charge of subatomic particles.
Mader - Chapter 02 #1
Section: 02.01
Topic: Chemistry
2. Which one of the following is the smallest unit of matter that has all the properties of an element?
A. molecule
B. element
C. atom
D. compound
E. electron
Elements are comprised of one kind of atom. These atoms all bear the same atomic number having a
characteristic number or sub atomic particles that govern the properties of that element. Molecules have
more than one atom present, so they are not in their simplest form. Compounds are comprised of two or more
different elements.

3. Elements differ from each other in their ________.
A. physical properties only
B. atomic number only
C. type of subatomic particles
D. physical properties and atomic number
E. type of electrons
The number of protons in an element creates its atomic number. Different elements will have different numbers
of these particles and thus different atomic numbers. However, all elements have the same type of subatomic
particles, those being protons, neutrons and electrons.

4. Regarding atoms, identify which statement below is correct.
A. An element may be composed of several types of atoms.
B. The nucleus of an atom contains protons and electrons.
C. The number and arrangement of electrons in an atom governs its chemical activity.
D. The positive charges of an element are carried by the electrons.
E. The neutral charges of an element are carried by the protons.
An atom is comprised of subatomic particles. The protons bear a positive charge, are found in the nucleus, and
their number creates the atomic number assigned to that element. The neutrons are found in the nucleus as
well and they with the protons create the majority of an atom's mass. The electrons bear a negative charge and
govern the elements reactivity.
