Biology Standard 1
The fundamental life processes of plants and animals depend on a variety of chemical reactions that occur in specialized areas of the organism's cells.
Biology Standard 2
Mutation and sexual reproduction lead to genetic variation
in a population.
Biology Standard 3
A multicellular organism develops from a single zygote, and
its phenotype depends on its genotype, which is established
at fertilization.
Biology Standard 4
Genes are a set of instructions encoded in the DNA sequence
of each organism that specify the sequence of amino acids in
proteins characteristic of that organism.
Biology Standard 5
The genetic composition of cells can be altered by incorporation
of exogenous DNA into the cells.
Biology Standard 6
Stability in an ecosystem is a balance between competing
effects.
Biology Standard 7
The frequency of an allele in a gene pool of a population
depends on many factors and may be stable or unstable over time.
Biology Standard 8
Evolution is the result of genetic changes that occur in
constantly changing environments.
Biology Standard 9
As a result of the coordinated structures and functions of
organ systems, the internal environment of the human body remains
relatively stable (homeostatic) despite changes in the outside
environment.
Biology Standard 10
Organisms have a variety of mechanisms to combat disease.
