All living things require and outside source of materials and energy; the sum total
of all chemical reactions that occur within a cell to provide these materials and
energy is called __________.
metabolism
However, for these processes to continue, living things must maintain
___________ or a constant internal environment.
homeostasis
This includes maintaining a stable __________, moisture, level, and acidity.
temperature
Some organisms depend on _____________ to maintain this constant internal
environment. For example, lizards lounge on rocks in sunny locations to warm
their bodies and seek shade to cool their bodies.
behaviors
Other organisms rely on __________________ to maintain this constant internal
environment. For example, penguins have extra layers of feathers and a layer of
blubber to keep warm and dry in cold, snowy conditions.
physical modifications
These are both examples of ___________, or modifications that make organisms
suited to their way of life.
adaptations
Levels of classification from least inclusive, to most inclusive... Order, family,
genus, species, phylum, class, kingdom, domain
species, genus, family, order, class, phylum, kingdom, domain
Scientific experiments
A researcher wants to test his hypothesis that a diet low in fats will lead to a
decrease in LDL cholesterol over several months of time. From the following list
of statements, select those that will lead to the best experimental design.
All ((except)) for:
Measure the cholesterol level of two randomly chosen men at the onset of one study.
Prescribe to all patients a carefully regimented diet that contains a variety of low-fat
options, tailored to the caloric needs of each man.
Discard from the results the men whose cholesterol readings did not fit the hypothesis.
Science and social responsibility
The following are examples of a few of the benefits and costs of using
technology. For each, decide if it describes a cost or a benefit and classify it
accordingly.
