SBI4U Biology – Grade 12 (University)

  • Grade 12

PREREQUISITE: Biology, Grade 11, University Preparation

GRADE: 12 (University)

AVAILABILITY: Full-time – All Campuses, Part-time – All Campuses, Private – All campuses, Blyth Academy Online


Course Overview

SBI4U online 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. In SBI4U online, 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. This Biology course prepares students for advanced studies in the sciences through a comprehensive curriculum, whether it’s taken as an in-person class on campus or taken online. Virtual and in-person versions of this class answer the same five essential questions on biochemistry, metabolic processes, molecular genetics, homeostasis, and population dynamics. Both modes of learning offer a solid foundation for university study of the sciences, focusing on theory and research.

Course Outline

Review the course outline below for SBI4U Biology – Grade 12 (University). Blyth Academy creates this course’s curriculum. It’s divided into five units, each of which has a unique, essential question and focuses on the theory that will provide essential background knowledge for further learning. The units are biochemistry, with a focus on chemical reactions that sustain life; metabolic processes, with a focus on plants and animals; molecular genetics, with coursework on gene expression; homeostasis, with a focus on systems interaction to create homeostasis; and population dynamics, with a focus on human population growth and its effects.

The course outline remains the same, whether taken online or on campus. Learn more about the five units and how their essential questions inspire learning that will further help students continue on the path to studying biology and other scientific subjects.


Essential Question: What is the relationship between the chemical properties of biological molecules and the biochemical reactions required to maintain normal cellular function and sustain life?

In this unit, students will learn about electronegativity and intermolecular forces. Students will also learn about organic compounds and the importance of functional groups. Students will investigate macromolecules including carbohydrates, lipids, proteins and nucleic acids. Students will take a closer look at enzymes and enzyme activity as well as the different parts of a cell and their functions including membrane structure, function and transport.

Metabolic Processes

Essential Question: How and why do plants and animals obtain energy in different ways?

In this unit, students will learn about metabolic processes including cellular respiration and it’s various stages. Students will also learn about Photosynthesis and light dependent and light independent reactions.

Molecular Genetics

Essential Question: How are genes expressed?

In this unit, students will learn about the structure of DNA and RNA as well as DNA replication. They will learn about protein synthesis; transcription and translation. Students will investigate gene regulation and how mutations occur. Students will also learn about various biotechnological tools and techniques.


Essential Question: How do the endocrine, excretory and nervous system interact through feedback mechanisms in order to maintain homeostasis?

In this unit, students will learn about homeostasis and it’s significance. Students will also learn about the nervous system and the functions of both the central and peripheral nervous systems. They will investigate the endocrine system and learn about the hormones that affect their blood sugar, stress and metabolism. Students will also learn about the different reproductive hormones. Students will learn about the excretory system and why it is important for their bodies to excrete wastes.

Population Dynamics

Essential Question: How are human population growth, personal consumption, technological development and ecological footprint related?

In this unit, students will learn about population dynamics. Students will investigate the changes in population, factors that regulate natural populations and the effects of human population growth, personal consumption and technological development.


The final exam will make up 30% of your grade and must be scheduled 10 days in advance. While there’s no final project or research paper for this course, the final exam is two hours and is a rather significant part of your grade.
