After spending an hour working outside in the hot, sunny
weather, a person typically perspires and will need to drink
water. This is part of what?
Based on the evolutionary tree of the three domains, which
of the following is true?
A. All three domains have a common ancestor.
B. Domain Bacteria and Domain Archaea are more closely
related to each other than to Domain Bacteria.
C. The Eukarya have remained the same throughout
D. All three domains are equally related to one another.
E. The Eukarya are the common ancestors to the three
All three domains have a
A biologist is studying how the pollution affects algae growth
and snail populations in a portion of Lake Erie. What level
of organization is she studying?
Charles Darwin, after observing variability among plant and
animal species in various locations proposed an explanation
which included reasons that species could be modified
through genetic variation, leading to measurable similarity
and difference. The evidence for his proposal came from
biological, geographic and geological observations. His
proposal allowed for prediction of new species that might be
found in new settings, based on environmental conditions.
Darwin's proposal is an example of what?
The dynamics of any ecosystem include what major
The flow of energy from
sunlight to producers
and then to consumers,
and finally, the recycling
of chemical nutrients.
Female fireflies emit flashes of light that attract males. This
communication is an example of which characteristic of life?
Interactions with the
The four kingdoms included in the domain Eukarya are
Plantae, and Animalia.
How does a theory differ from a hypothesis?
A theory has predictive
power for similar
phenomena that haven't
been observed yet, ties
together many existing
observations, has more
evidence than a
hypothesis, and is
broader in scope than a
In an experimental procedure, the researcher measures
changes, such as cell growth rates, numbers of patients with
a disease, etc. in response to factors manipulated at the
beginning of the experiment.
This measure of change in response to the initial conditions
is called the what?
In an experiment, which of the following is not a true
A. The larger the sample size the more meaningful the
B. It is important to standardize aspects of an experiment
that might affect the outcome, other than the independent
C. Without the proper control an experiment is not valid.
D. The smaller the sample size the more meaningful the
The smaller the sample
size the more meaningful
In the different Hawaiian Islands, various species of the
honeycreeper birds have a variety of different length of
their bills (beaks), but the entire species have a similar size
and body shape. This is an example of what?
In the plant leaves the chloroplasts convert the energy of
the sunlight into what?
The potential energy of
the chemical bonds in
