all the places they are found on Earth.
biosphere
48A(n) _______ is a particular type of living thing
that can reproduce by interbreeding among
themselves.
Present your answers!
species
49What are the four characteristics of life?
Present your answers!
- All organisms are made up of one or more cells
- All organisms need a source of energy for their
life processes. - All organisms must react to their environment to
survive. - Members of a species must have the ability to
reproduce.
50What are the differences between sexual and
asexual reproduction?
Present your answers!
In sexual reproduction there are two parents and
in asexual reproduction there is only one parent.
In sexual reproduction there is a combining of
genetic information to create a genetically
unique organism and in asexual reproduction the
offspring is genetically identical to the parent.
51What is the difference between reproduction and
development?
Present your answers!
Reproduction is producing new individuals and
development is the maturing of an organism.
52What are some examples of levels of biological
systems? (list three)
Present your answers!
Molecule, organelle, cell, tissue, organ, organ
system, individual, population, species,
ecosystem, biosphere
53A(n) _______ is a physical environment (such as a
desert, coral reef, forest, etc.) with different
species that interact with one another and with
nonliving things.
Present your answers!
ecosystem
54________ is a change in the genetic makeup of a
population of a species.
Present your answers!
evolution
55In _______ ________, a genetic, or inherited,
trait helps some individuals of a species survive
and reproduce more successfully than other
organisms in a particular environment (think
survival of the fittest).
Present your answers!
Natural selection
56Give one example of quantitative data and one
example of qualitative data (be sure to label
which is which).
Present your answers!
Answers vary. Ex. Of quantitative The ball
weighs 8 kg. Ex. Of qualitative The ball is red.
57A scientist is investigating the effect of daily
exercise on a persons cholesterol level. What is
the independent variable in this experiment?
Present your answers!
The daily exercise
58A scientist is investigating the effect of daily
exercise on a persons cholesterol level. What is
the dependent variable in this experiment?
Present your answers!
The cholesterol level
59A scientist is investigating the effect of daily
exercise on a persons cholesterol level. What is
one controlled variable in this experiment?
Present your answers!
Answers vary. Ex. The diet of the people in both
groups should be the same.
60A scientist is investigating the effect of daily
exercise on a persons cholesterol level.
Describe the control group in this experiment.
Present your answers!
The control group would not do the daily exercise.
61A scientist is investigating the effect of daily
exercise on a persons cholesterol level.
Describe the experimental group in this
experiment.
Present your answers!
The experimental group would do the daily
exercise.
62A scientist is investigating the effect of daily
exercise on a persons cholesterol level. What
sample size for each group would you recommend?
Present your answers!
Answers vary something large
63Why is it important to have a large sample size
in experiments?
Present your answers!
The sample size should be large so that
individuals in the sample are representative of
the entire set.
64What information or types of images does an MRI
reveal that an x-ray cannot?
Present your answers!
X-rays reveal only the skeleton whereas an MRI
reveals a complete view of all of the tissues in
a part of the body (including skin and muscle).
65Give one reason why a scientist may choose to use
a light microscope rather than an SEM or a TEM.
Present your answers!
In order to view a specimen using an electron
microscope, the specimen must be dead so to see
a living specimen.
66Give one reason why a scientist may choose to use
an SEM rather than a TEM.
Present your answers!
An SEM provides a 3-D image of the surface of the
specimen whereas the TEM provides a 2-D image of
the inside of the specimen so to see the surface
of the specimen.
67Give one reason why a scientist may choose to use
a TEM rather than a light microscope.
Present your answers!
A TEM has greater magnification power than a
light microscope so to see the specimen in more
detail.
68When do scientists use computer models?
Present your answers!
Scientists use computer models when they want to
study complex systems on a large scale (ex.
Epidemiology model). Also, in general, scientists
use computer models when actual experiments are
not safe, ethical, or practical.
69What are transgenic organisms? Give one example.
Present your answers!
Transgenic organisms are organisms that have
genes from more than one species or have altered
copies of their own genes. Ex. Transgenic
bacteria can make human insulin to treat people
with diabetes Ex. Transgenic sheep and cows can
make human antibodies and proteins Ex.
Genetically modified foods (such as
insect-resistant crops)
70Give one example of an adaptation.
Present your answers!
Answers will vary. Ex. The bright color of
flowers attract pollinators to the flower.
