7.13: Organisms and environments. The student knows how systems are organized and function to support the health of an organism and how traits are inherited. The student is expected to:
7.13.C: compare the results of asexual and sexual reproduction of plants and animals in relation to the diversity of offspring and the changes in the population over time; and
7.13.D: describe and give examples of how natural and artificial selection change the occurrence of traits in a population over generations.
