development that is consistent with the requirements prescribed in this section
and that is age-appropriate, factual and focused on only prenatal human
development as a biological process.
3. Include instruction on fetal and
prenatal human development in the competency requirements prescribed pursuant
to section 15-701 or 15-701.01, or both, in the area of science.
4. Require that instruction provided
pursuant to this section include an overview of all of the following:
(
a
) Prenatal
human development that explains the biological process by which a human
develops from a single cell, through successive stages, before birth.
(
b
) Fertilization
and early cellular development, including:
(
i
) The
formation of a zygote through the union of human reproductive cells.
(

development of a blastocyst.

iv
) Implantation
of the blastocyst into the uterine wall.

) The
placenta and its role in providing nutrients and oxygen and removing waste.
(
iii
) The
umbilical cord and its function as a connection between the fetus and the
placenta.
(
f
) General
principles of healthy prenatal development, including only biological and
physiological factors that support normal growth and organ development.
5. Require that instruction provided
pursuant to this section meet both of the following:
(
a
) Be
descriptive and age appropriate.
(
b
) Not include
instruction on sexual activity, sexual behavior, contraception, abortion
