Description de cours
This course features in-depth study of the concepts and processes that occur in biological systems. You 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.
Note: This course is only delivered online through My ILC. All lessons can be accessed at the ILC website. All assignments must be submitted online using the online work submission tool. You will learn more about how to do this once you get started in the course. For special circumstances,contact Learner Services.
Pour ce cours, il faut soumettre le travail en ligne en utilisant Microsoft Word © ou OpenOffice Writer.
Unit 1: Biochemistry
Life is the result of biochemical reactions. Understanding which biological molecules areimportant and how their reactions occur is fundamental to advances in health sciencesand biotechnology, and managing our natural world. In this unit, you’ll look at some ofthese important biological molecules and how they interact to make cells function.The unit begins with a review of basic chemistry, laying the foundation for understandingthe chemical structures and processes that occur in cells. You will then learn about someimportant biomolecules and how they interact. Next, you will investigate how proteins,known as enzymes, can control chemical reactions in living cells. Finally, you will be ableto apply your knowledge of biomolecules, as you take a closer look at the cells structure and function.
Unit 2: Metabolic Processes
All metabolic processes involve chemical changes that either build up biological molecules or break them down. This involves energy. The ultimate source of this energy is sunlight, captured in the process of photosynthesis. Respiration is the process of using this energy to make cells function.
This unit begins with an introduction to energy and metabolism. Next, you will learn about the biochemistry of respiration and the importance that this plays in health and nutrition. You will follow this with an examination of the process of photosynthesis. The unit concludes with a look at the biochemical similarities between photosynthesis and respiration, and how these similarities relate to the evolution of these two processes
Unit 3: Molecular Genetics
DNA contains the genetic information that governs all of the metabolic processes in living organisms. The discovery of DNA as the molecule responsible for storing genetic information was a landmark discovery in biology.
In the first lesson of this unit, you will learn how this discovery was made and how it reveals the process of science. The unit continues with an examination of the biochemistry of DNA and how its information is translated into proteins that determine how cells operate. Finally, you will explore how new biotechnologies in health, agriculture, and ecology are being developed, based on scientists’ expanding knowledge of how to manipulate DNA.
Unit 4: Homeostasis
Living organisms function in a way that avoids environmental extremes. This “steady state” of being is known as homeostasis. In this unit, you will learn how homeostasis operates through feedback mechanisms, and why it is critical for maintaining a healthy body.
The unit begins with an overview of the process of homeostasis. Next, you will examine three body systems that play vital roles in maintaining homeostasis: the excretory, endocrine, and nervous systems. Throughout the unit, you will learn how your lifestyle choices can affect the functioning of these systems and the consequences that this has on your health.
Unit 5: Population Dynamics
Understanding the population dynamics of species, including humans, is key to solving many of our global environmental problems. This unit starts with an examination of the population growth of humans from our beginning as a species, to today. You will investigate the factors causing our recent dramatic pattern of population growth, as well as its impacts on society and the environment.
The unit continues with an examination of the factors that characterize populations and how these factors interrelate to create changes in population size. You will learn how to use simple mathematical relationships to model population growth. The last lesson investigates how the population dynamics of species, including humans, are interconnected to produce the complex dynamics found in the web of life.
