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.

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. |
|
7.4.5 Explain how food provides the fuel & the building
material for all organisms. |
|
7.4.6 Describe how plants use the energy from light to make
sugars from carbon dioxide & water to produce food that can be used
immediately or stored for later use. |
|
7.4.7 Describe how organisms that eat plants break down the plant
structures to produce the materials & energy that they need to survive,
& in turn, how they are consumed by other organisms. |
|
8.4.5 Explain that energy can be transferred from one form to
another in living things. |
|
8.4.6 Describe how animals get their energy from oxidizing their
food & releasing some of this energy as heat. |
|
B.1.6 Show that a living cell is composed mainly of a small
number of chemical elements - carbon, hydrogen, nitrogen, oxygen,
phosphorous, and sulfur. Recognize that carbon can join to other carbon atoms
in chains and rings to form large and complex molecules. |
|
B.1.9 Recognize and describe that both living and nonliving
things are composed of compounds, which are themselves made up of elements
joined by energy-containing bonds, such as those in ATP. |
|
B.1.10 Recognize and explain that macromolecules such as lipids
contain high energy bonds as well. |
|
Developmental and
Organismal Biology |
|
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. |
Genetics
|
|
B.1.28 Illustrate that the sorting and recombination of genes in
sexual reproduction results in a great variety of possible gene combinations
from the offspring of any two parents. Recognize that genetic variation can
occur from such processes as crossing over, jumping genes, and deletion and
duplication of genes. |
|
B.1.29 Understand that and explain how the actions of genes,
patterns of inheritance, and the reproduction of cells and organisms account
for the continuity of life, and give examples of how inherited
characteristics can be observed at molecular and whole-organism levels - in
structure, chemistry, or behavior. |
|
Evolution |
|
B.1.36 Trace the relationship between environmental changes and
changes in the gene pool, such as genetic drift and isolation of
sub-populations. |
|
Ecology |
|
7.4.2 Describe that all organisms, including the human species,
are part of & depend on two main interconnected global food webs, the
ocean food web & the land food web. |
|
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. |
|
8.4.4 Describe how matter is transferred from one organism to
another repeatedly & between organisms & their physical environment. |
|
8.4.8 Describe how environmental conditions affect the survival
of individual organisms & how entire species may prosper in spite of the
poor survivability or bad fortune of individuals. |
|
B.1.38 Understand and explain the significance of the
introduction of species, such as zebra mussels, into American waterways, and
describe the consequent harm to native species and the environment in
general. |
|
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. |
