BIOLOGY EXAM 1 QUESTION WITH
ACCURATE SOLUTIONS.
The best classification system is that which most closely
A) conforms to traditional, Linnaean taxonomic practices.
B) unites organisms that possess similar morphologies.
C) reflects evolutionary history.
D) reflects the basic separation of prokaryotes from eukaryotes.
C
Some molecular data place the giant panda in the bear family (Ursidae)
but place the lesser panda in the raccoon family (Procyonidae).
Consequently, the morphological similarities of these two species are
probably due to
A) inheritance of acquired characteristics.
B) possession of shared primitive characters.
C) sexual selection.
D) inheritance of shared derived characters.
E) possession of analogous structures.
E
Which process occurred frequently in the early history of the three domains
on Earth, and makes determining phylogenetic relationships of that time
difficult?
A) meiosis
B) mitosis
C) horizontal gene transfer
D) binary fission
E) alternative RNA splicing
,C
The best experimental design _____.
includes a large sample size and a control, and alters only one condition
between the controls and the experimental condition
In comparison to eukaryotes, prokaryotes _____
are smaller
Which of the following types of cells utilize deoxyribonucleic acid (DNA)
as their genetic material but do not have their DNA encased within a
nuclear envelope?
archaean
A controlled experiment _____.
includes at least two groups, one of which does not receive the experimental
treatment
In presenting data that result from an experiment, a group of students
show that most of their measurements fall on a straight diagonal line on
their graph. However, two of their data points are "outliers" and fall far to
one side of the expected relationship. What should they do?
Show all results obtained and then try to explore the reason(s) for these
outliers
The application of scientific knowledge for some specific purpose is known
as _____.
Technology
Which of the following best describes a model organism?
It is well studied, it is easy to grow, and results are widely applicable.
How does a scientific theory differ from a scientific hypothesis?
Theories are usually an explanation for a more general phenomenon;
hypotheses typically address more specific issues.
,In 1668, Francesco Redi performed a series of experiments on
spontaneous generation. He began by putting similar pieces of meat into
eight identical jars. Four jars were left open to the air, and four were
sealed. He then did the same experiment with one variation: Instead of
sealing four of the jars completely, he covered them with gauze (the gauze
excluded the flies while allowing the meat to be exposed to air). In both
experiments, he monitored the jars and recorded whether or not maggots
(young flies) appeared in the meat.
Refer to the paragraph on Redi's experiments. What hypothesis was being
tested in the initial experiment with open versus sealed jars?
Maggots do not arise spontaneously, but from eggs laid by adult flies.
You find yourself standing next to a beautiful rose bush. Which of the
following do you and the rose have in common?
You both are multicellular.
Why is a scientific topic best discussed by people of varying points of
view, from different subdisciplines, and representing diverse cultures?
Robust and critical discussion between diverse groups improves scientific
thinking.
Cells are _____.
characteristic of prokaryotic and eukaryotic organisms
A localized group of organisms that belong to the same species is called a
_____.
a population
Use the following information when answering the corresponding
question(s).

Refer to the paragraph on Redi's experiments. In both experiments, flies
appeared in all of the open jars and only in the open jars. Which one of
the following statements is correct?
The experiment supports the hypothesis that maggots arise only from eggs
laid by adult flies.
In the process of science, which of these is tested?
a hypothesis
Prokaryotes are classified as belonging to two different domains. What are
the domains?
bacteria and archae
Which of these is an example of inductive reasoning?
Hundreds of individuals of a species have been observed and all are
photosynthetic; therefore, the species is photosynthetic.
Bacteria, Archae, and Eukarya are
the three major domains of life
Which branch of biology is concerned with the naming and classifying of
organisms?
taxonomy
How many electrons will a single atom of sulfur with no charge and no
bonds have in its valence shell (see the figure above)?
