It is designed for non-science majors and fulfills the science requirement for most associate degrees at Great Basin College.

• Credits: 3

• Prerequisites: MATH 96 or higher, or appropriate placement score

• Textbook: Campbell Essential Biology, 7th ed. (2019), Pearson

• Instructor: Kara Coates

• Delivery: Online, with weekly modules and assessments via Mastering Biology

Course Topics and Schedule

The course is structured into weekly modules, each focusing on a major topic in biology. Below is a summary of the main topics and their subtopics, as outlined in the course schedule.

1. Introduction to Biology

This topic covers the scope of biology, the scientific method, and the importance of biology in everyday life.

• Definition: Biology is the scientific study of life and living organisms.

• Scientific Method: A systematic approach to inquiry involving observation, hypothesis formation, experimentation, and conclusion.

• Application: Understanding how biology impacts health, environment, and society.

2. Essential Chemistry for Biology

This section introduces the basic chemical principles that underlie biological processes.

• Atoms and Molecules: The building blocks of matter; atoms combine to form molecules essential for life.

• Macromolecules: Large molecules such as carbohydrates, proteins, lipids, and nucleic acids.

• Example: Water's role as a solvent in biological systems.

3. The Working Cell

Explores cell structure and function, including the differences between prokaryotic and eukaryotic cells.

• Cell Theory: All living things are composed of cells; the cell is the basic unit of life.

• Cell Organelles: Structures such as the nucleus, mitochondria, and ribosomes, each with specific functions.

• Example: The role of the plasma membrane in regulating what enters and leaves the cell.

4. Cellular Respiration and Photosynthesis

Examines how cells obtain and use energy.

• Cellular Respiration: The process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

• Photosynthesis: The process by which plants, algae, and some bacteria convert light energy, carbon dioxide, and water into glucose and oxygen.

• Equation for Cellular Respiration:

• Equation for Photosynthesis:

5. Cellular Reproduction: Mitosis and Meiosis

Focuses on how cells divide and reproduce.

• Mitosis: Cell division resulting in two genetically identical daughter cells.

• Meiosis: Cell division that produces gametes (sperm and egg) with half the number of chromosomes.

• Importance: Mitosis is essential for growth and repair; meiosis is essential for sexual reproduction.

6. Patterns of Inheritance and DNA Structure

Explores how genetic information is passed from one generation to the next.

• Genes: Units of heredity made of DNA.

• DNA Structure: Double helix composed of nucleotides (adenine, thymine, cytosine, guanine).

• Example: Mendelian inheritance patterns (dominant and recessive traits).

7. DNA Technology and How Populations Evolve

Introduces modern genetic technologies and the principles of evolution.

• DNA Technology: Techniques such as PCR, gene cloning, and genetic engineering.

• Evolution: The process by which populations change over time through mechanisms such as natural selection and genetic drift.

• Equation for Hardy-Weinberg Equilibrium:

• Where: p and q represent the frequencies of two alleles in a population.

8. Biological Diversity, Populations, and Ecosystems

Examines the diversity of life and the interactions between organisms and their environments.

• Biodiversity: The variety of life in all its forms and levels, including species, genetic, and ecosystem diversity.

• Population Ecology: Study of populations in relation to environment, including factors that affect population size and growth.

• Community and Ecosystem Ecology: Interactions among species and between organisms and their physical environment.
