BIO 110 EXAM #1 MULTIPLE CHOICE
population - Answers- A localized group of organisms that belong to the same species
is called a
oxygen. - Answers- Organisms interact with their environments, exchanging matter and
energy. For example, plant chloroplasts convert the energy of sunlight into
light energy - Answers- The main source of energy for producers in an ecosystem is
reductionism - 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 - 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 - Answers- Which branch of biology is concerned with the naming and
classifying of organisms?
All eukarya belong to one domain. - Answers- What is the major difference between a
kingdom and a domain?
absorbing dissolved nutrients - Answers- What is the major distinguishing characteristic
of fungi?
Prokaryotes characterized as extremophiles that share some bacterial and some
eukaryotic traits. - Answers- What are archaea?
a hypothesis - 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.
- Answers- A controlled experiment is one in which
technology. - Answers- The application of scientific knowledge for some specific
purpose is known as
It is testable &
It is falsifiable - 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. - 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. - Answers- Which of
the following best describes a model organism?
Robust and critical discussion between diverse groups improves scientific thinking. -
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. - Answers- The
advantage of light microscopy over electron microscopy is that
separate the major organelles so that their particular functions can be determined. -
Answers- A primary objective of cell fractionation is to
ribosomes - Answers- Prokaryotic and eukaryotic cells generally have which of the
following features in common?
Bacteria and Archaea - 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 - Answers- Which of these individuals is likely to be most successful in an
evolutionary sense?
natural selection - 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
nucleus, mitochondria, ribosomes - 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. - Answers- Green fluorescent protein (GFP)
can be used to fluorescently label a specific protein in cells by genetically engineering
cells to synthesize the target protein fused to GFP. What is the advantage of using GFP
fusions to visualize specific proteins, instead of staining cells with fluorescently labeled
probes that bind to the target protein?
light microscopy - Answers- What technique would be most appropriate to use to
observe the movements of condensed chromosomes during cell division?
