BIO 110 EXAM #1 MULTIPLE CHOICE
QUESTIONS AND ANSWERS
population - Correct Answers -A localized group of organisms that belong to the same
species is called a
oxygen. - Correct Answers -Organisms interact with their environments, exchanging
matter and energy. For example, plant chloroplasts convert the energy of sunlight into
light energy - Correct Answers -The main source of energy for producers in an
ecosystem is
reductionism - Correct Answers -To understand the chemical basis of inheritance, we
must understand the molecular structure of DNA. This is an example of the application
of which concept to the study of biology?
negative feedback - Correct Answers -When the body's blood glucose level rises, the
pancreas secretes insulin and, as a result, the blood glucose level declines. When the
blood glucose level is low, the pancreas secretes glucagon and, as a result, the blood
glucose level rises. Such regulation of the blood glucose level is the result of
taxonomy - Correct Answers -Which branch of biology is concerned with the naming
and classifying of organisms?
ribosomes - Correct Answers -Prokaryotic and eukaryotic cells generally have which of
the following features in common?
Bacteria and Archaea - Correct Answers -Prokaryotes are classified as belonging to two
different domains. What are the domains?
an organism that dies after five days of life but leaves 10 offspring, all of whom survive
to reproduce - Correct Answers -Which of these individuals is likely to be most
successful in an evolutionary sense?
natural selection - Correct Answers -Through time, the lineage that led to modern
whales shows a change from four-limbed land animals to aquatic animals with two limbs
that function as flippers. This change is best explained by
, All eukarya belong to one domain. - Correct Answers -What is the major difference
between a kingdom and a domain?
absorbing dissolved nutrients - Correct Answers -What is the major distinguishing
characteristic of fungi?
Prokaryotes characterized as extremophiles that share some bacterial and some
eukaryotic traits. - Correct Answers -What are archaea?
a hypothesis - Correct Answers -When applying the process of science, which of these
is tested?
there are at least two groups, one of which does not receive the experimental treatment.
- Correct Answers -A controlled experiment is one in which
technology. - Correct Answers -The application of scientific knowledge for some specific
purpose is known as
It is testable &
It is falsifiable - Correct Answers -Which of the following are qualities of any good
scientific hypothesis?
The control group is matched with the experimental group except for the one
experimental variable. - Correct Answers -Which of the following is the best description
of a control for an experiment?
It is well studied, easy to grow, and results are widely applicable. - Correct Answers -
Which of the following best describes a model organism?
Robust and critical discussion between diverse groups improves scientific thinking. -
Correct Answers -Why is a scientific topic best discussed by people of varying points of
view, a variety of subdisciplines, and diverse cultures?
light microscopy allows one to view dynamic processes in living cells. - Correct Answers
-The advantage of light microscopy over electron microscopy is that
separate the major organelles so that their particular functions can be determined. -
Correct Answers -A primary objective of cell fractionation is to
nucleus, mitochondria, ribosomes - Correct Answers -Which of the following correctly
lists the order in which cellular components will be found in the pellet when
homogenized cells are treated with increasingly rapid spins in a centrifuge?
GFP fusions enable one to track changes in the location of the protein in living cells;
staining usually requires preserved cells. - Correct Answers -Green fluorescent protein
(GFP) can be used to fluorescently label a specific protein in cells by genetically
