B.1.14 Recognize and explain that communication and/or
interaction are required between cells to coordinate their diverse activities.
|
Molecules and Cells |
|
7.4.4 Explain that the basic functions of organisms, such as
extracting energy from food & getting rid of wastes, are carried out
within the cell & understand that the way which cells function is similar
in all organisms. |
|
B1.1Recognize that and explain how the many cells in an
individual can be very different from one another, even though they are all
descended from a single cell and thus have essentially identical genetic
instructions. Understand that different parts of the genetic instructions are
used in different types of cells and are influenced by the cellÕs environment
and past history. |
|
B.1.7 Explain that complex interactions among the different
kinds of molecules in the cell cause distinct cycles of activities, such as
growth and division. Note that cell behavior can also be affected by
molecules from other parts of the organism, such as hormones. |
|
B.1.8 Understand and describe that all growth and development is
a consequence of an increase in cell number, cell size, and/or cell products.
Explain that cellular differentiation results from gene expression and/or
environmental influence. Differentiate between mitosis and meiosis. |
|
Developmental and
Organismal Biology |
|
7.4.10 Explain that the amount of food energy (calories) a person
requires varies with body weight, age, sex, activity level, & natural
body efficiency. Understand that regular exercise is important to maintain a
healthy heart/lung system, good muscle tone, & strong bone structure. |
|
B.1.15 Understand and explain that, in biological systems,
structure and function must be considered together. |
|
B.1.16 Explain how higher levels of organization result from
specific complexing and interactions of smaller units and that their
maintenance requires a constant input of energy as well as new material. |
|
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. |
|
B.1.19 Recognize and describe that metabolism consists of the
production, modification, transport, and exchange of materials that are
required for the maintenance of life. |
|
B.1.20 Recognize that and describe how the human immune system
is designed to protect against microscopic organisms and foreign substances
that enter from outside the body and against some cancer cells that arise
within. |
Genetics
|
|
B.1.26 Demonstrate how the genetic information in DNA molecules
provides instructions for assembling protein molecules and that this is
virtually the same mechanism for all life forms. |
|
Evolution |
|
Ecology |
|
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.1.43 Understand that and describe how organisms are influenced
by a particular combination of living and nonliving components of the
environment. |
|
B.1.45 Recognize that and describe how the physical or chemical
environment may influence the rate, extent, and nature of the way organisms
develop within ecosystems. |
