Organisms & Environments - Inherited Traits
3.13.A explore and explain how external structures and functions of animals such as the neck of a giraffe or webbed feet on a duck enable them to survive in their environment;
5.13.A analyze the structures and functions of different species to identify how organisms survive in the same environment;
6.13.C describe how variations within a population can be an advantage or disadvantage to the survival of a population as environments change
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
