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.
|
Molecules and Cells |
|
7.4.1Explain that similarities among organisms are found in
external & internal anatomical features, including specific
characteristics at the cellular level, such as the number of chromosomes.
Understand that these similarities are used to classify organisms since they
may be used to infer the degree of relatedness among organisms. |
|
7.4.3 Explain how, in sexual reproduction, a single specialized
cell from a female merges with a specialized cell from a male & this
fertilized egg carries genetic information from each parent & multiplies
to form the complete organism. |
|
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.1.4 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. |
|
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 |
|
B.1.11 Describe that through biogenesis all organisms begin
their life cycles as a single cell and that in multicellular organisms,
successive generations of embryonic cells form by cell division. |
|
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
|
|
8.4.1 Differentiate between inherited traits, such as hair color
or flower color, & acquired skills, such as manners. |
|
8.4.2 Describe that in some organisms, such as yeast or bacteria,
all genes come from a single parent, while in those that have sexes,
typically half of the genes come from each parent. |
|
8.4.3 Recognize/describe that new varieties of cultivated plants,
such as corn & apples, & domestic animals, such as dogs & horses,
have resulted from selective breeding for particular traits. |
|
8.4.7 Recognize & explain that small genetic differences
between parents & offspring can accumulate in successive generations so
that descendants are very different from their ancestors. |
|
B.1.21 Understand and explain that the information passed from
parents to offspring is transmitted by means of genes which are coded in DNA
molecules. |
|
B.1.22 Understand and explain the genetic basis for MendelÕs
laws of segregation and independent assortment. |
|
B.1.23 Understand that and describe how inserting, deleting, or
substituting DNA segments can alter a gene. Recognize that an altered gene
may be passed on to every cell that develops from it, and that the resulting
features may help, harm, or have little or no effect on the offspringÕs
success in its environment. |
|
B.1.24 Explain that gene mutations can be caused by such things
as radiation and chemicals. Understand that when they occur in sex cells, the
mutations can be passed on to offspring; if they occur in other cells, they
can be passed on to descendant cells only. |
|
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. |
|
AND it is necessary to understand how genes influence the morphology
of the organism. |
|
Evolution |
|
B.1.30 Understand and explain that molecular evidence
substantiates the anatomical evidence for evolution and provides additional
detail about the sequence in which various lines of descent branched off from
one another. |
