Interdependent Relationships in Ecosystems...
Carrying capacity in ecosystems, biodiversity, populations, complex interactions for stable vs. neww ecosystems, human activities on biodiversity and environment, group behavior impacts on survival and reproduction, adverse impacts of human activity.

Inheritance and Variation
of Traits... Mitosis (cell division), producing and maintaining complex organisms, DNA vs chromosomes, meiosis and new genetic combinations, replication errors, environmental factors and mutations,statistics and probability in variation / distribution of expressed traits, population
|
Natural Selection and Evolution...
Common ancestry & biological evolution, evolution results from 1. potential for a species to increase, genetic variation due to sexual reproduction / mutation, 3. competition for limited resources, 4. selected organisms are better able to survive and reproduce in the environmnent; organisms' heritable traits, natural selection and adaptation of populations, new species, species extinction

NGSS - Next Generation Science Standards
Key concepts that help make sense of life science. The ideas are building upon students’ science understanding of disciplinary core ideas, science and engineering practices, and crosscutting concepts from earlier grades. There are five life science topics in high school: 1) Structure and Function, 2) Inheritance and Variation of Traits, Matter and Energy in Organisms and Ecosystems, 4) Interdependent Relationships in Ecosystems, and 5) Natural Selection and Evolution
