B.1.5 Demonstrate that most cells function best within a narrow
range of temperature and acidity. Note that extreme changes may harm cells,
modifying the structure of their protein molecules and therefore, some possible
functions.

Molecules and Cells |
|
B.1.4 Understand and describe that the work of the cell is
carried out by the many different types of molecules it assembles, such as proteins,
lipids, carbohydrates, and nucleic acids. |

Organismal Biology |

B.1.17 Understand that and describe how the maintenance of a
relatively stable internal environment is required for the continuation of
life and explain how stability is challenged by changing physical, chemical,
and environmental conditions, as well as the presence of disease agents. |
|
B.1.18 Explain that the regulatory and behavioral responses of
an organism to external stimuli occur in order to maintain both short- and
long-term equilibrium. |

7.4.8 Understand & explain that as any population of
organisms grows, it is held in check by one or more environmental factors. These
factors could result in depletion of food or nesting sites and/or increased
loss to increased numbers of predators or parasites. Give examples of some
consequences of this. |
|
7.4.13 Explain that the environment may contain dangerous levels
of substances that are harmful to human beings. Understand, therefore, that
the good health of individuals requires monitoring the soil, air, & water
as well as taking steps to keep them safe. |
|
B.1.37 Explain that the amount of life any environment can
support is limited by the available energy, water, oxygen, and minerals, and
by the ability of ecosystems to recycle the residue of dead organic
materials. Recognize, therefore, that human activities and technology can
change the flow and reduce the fertility of the land. |
|
B.1.41 Recognize that and describe how human beings are part of
EarthÕs ecosystems. Note that human activities can, deliberately or
inadvertently, alter the equilibrium in ecosystems. |
|
B.1.43 Understand that and describe how organisms are influenced
by a particular combination of living and nonliving components of the
environment. |
