BIOL 1104 Exam 1 Study Questions with
Correct Answers
The genetic information of all living organisms is carried within , molecules. Each of th
ese molecules is composed of sequences of building blocks called which direct the
synthesis of cellular components. - CORRECT ANSWER -DNA, nucleotides
All of DNA contained within a cell comprises that cell's - CORRECT ANSWER -
genome
Photosynthetic organisms use the energy in light to
a) reduce CO2 and produce organic compounds
b) increase their temperature so that CO2 can react with other molecules
c) break down organic compounds into CO2 and heat - CORRECT ANSWER -a
The information stored within the nucleotides of molecules is used to direct the syn
thesis of cellular components. - CORRECT ANSWER -DNA
How do biologists explain the DIVERSITY of life (i.e. the fact that millions of different species in
habit our planet)?
a) The diversity of life is due to chance.
b) Living organisms are so diverse because they have evolved from a common ancestor.
c) Living organisms are so diverse because most offspring are able to survive long enough to pr
oduce additional offspring.
d) Living organisms are so diverse because they have evolved adaptations for many different lif
estyles and environments. - CORRECT ANSWER -d
, During cell division, a cell's is replicated and passed from one generation to the ne
xt. - CORRECT ANSWER -DNA
Which statement accurately describes how chemical and physical principles apply to biological
systems?
a) Certain complex processes in living systems are not subject to chemistry and physics laws.
b) Living systems must operate according to the laws of chemistry and physics.
c) Certain laws of physics and chemistry only apply to living systems.
d) Certain laws of physics and chemistry apply to living systems in a slightly modified form. -
CORRECT ANSWER -b
A biologist finds out that the fruit fly, Drosophila, makes a protein in its eyes that has a very si
milar structure when compared to a human protein that was just discovered in the newly sequ
enced human genome. The biologist concludes that the human protein might be important for
the proper development and working of the human eye. Which unifying theme in biology is illu
strated in this example?
a) All organisms are made of of one or more cells.
b) The information that specifies what a cell or an organism will look like is encoded in their D
NA.
c) There is a fundamental relationship between structure and function in all biological systems.
- CORRECT ANSWER -c
What is the ultimate source of energy for most of Earth's ecosystems?
a) Sunlight
b) Gravity
