SBI4U

Biology - 12


Course Description:

This course provides students with the opportunity for in-depth study of the concepts and processes that occur in biological systems. Students will study theory and conduct investigations in the areas of biochemistry, metabolic processes, molecular genetics, homeostasis, and population dynamics. Emphasis will be placed on the achievement of detailed knowledge and the refinement of skills needed for further study in various branches of the life sciences and related fields.

Prerequisite: SBI3U - Biology Grade 11

Course Outline

Unit 1: Biochemistry (22 hours)

In this unit, you will cover the topic of biochemistry and how it relates to the functioning of cells and organisms.

LESSON # LESSON NAME
1-1 The Cell
1-2 Cell Membranes            
1-3 Biological Molecules                                                   
1-4 Enzymes & Bichemical Reactions

 

Unit 2: Metabolic Processes (23 hours)

In this unit, you will explore some of the important metabolic processes that occur in cells to ensure their proper functioning and their survival.

LESSON # LESSON NAME
2-1 Energy in the Cell
2-2 Cellular Respiration
2-3 Photosynthesis

 

Unit 3: Molecular Genetics (23 hours)

In this unit, you will explore in depth the topic of molecular genetics.

LESSON # LESSON NAME
3-1 DNA Structure & Organization
3-2 DNA Replication
3-3 Transcription                            
3-4 Translation
3-5 Gene Regulation & Mutation

 

Unit 4: Homeostasis (23 hours)

Our bodies work hard to maintain a relatively constant internal environment despite a changing external environment, this is called homeostasis.  How do organ systems work together to maintain homeostasis and what happens when those systems stop working properly? You'll find out by the end of this unit.

LESSON # LESSON NAME
4-1 Homeostasis
4-2 The Excretory System                                              
4-3 The Endocrine System
4-4 The Nervous System        

 

Unit 5: Population Dynamics (19 hours)

With the world population currently over 6.5 billion people and its doubling time occurring in under 50 years, most people are concerned about what this means for our planet. In order to understand what the future holds, one must have an understanding of population dynamics.
In this unit, you will learn about the characteristics of populations and ways in which populations interact with one another. You will also learn ways to estimate populations and calculate population growth. You will examine the factors affecting human population growth, paying particular attention to the impact of exponential human growth on the environment and how it contributes to our overall ecological footprint.

5-1 Population Dynamics
5-2 Population Growth
5-3 Human Population & Human Impacts
