About This Course
ACE Approved 2025
Introduction to Biology addresses the fundamentals of biological science, from the structures and processes which demonstrate the unity of life, to the variations in organisms and ecosystems which highlight the diversity of life on Earth.
What You'll Learn
Identify the molecular structure of major components of cells and determine their use for cellular metabolism and functions.
Compare and contrast the structures, organization, and role in the environment of prokaryotes, eukaryotes, and viruses.
Compare and contrast the different forms of cellular reproduction and their effects on the genetic components of the cell and/or organism.
Outline the biochemical pathways used by plant and animal cells to maintain their metabolism and synthesize necessary molecules.
Analyze the effects of hereditary mechanisms and mutations on the genetics and phenotypes of organisms.
Identify methods of cellular communication and determine how these methods affect homeostasis and overall functioning of the cell.
Analyze the mechanisms involved in the microevolution of organisms.
Identify how the structures, behaviors, and resource needs of organisms determine their role in their environment and in the biosphere.
