Standard Set 2 Life Sciences
2 Plants and animals have
predictable life cycles As a basis for
understanding this concept:
2.a. Students know that organisms
reproduce offspring of their own kind
and that the offspring resemble their
parents and one another.
2.c. Students know many
characteristics of an organism are inherited from the parents Some characteristics are caused or influenced
by the environment.
2.d. Students know there is variation
among individuals of one kind within
a population.
