Grade 10 Science Q4 - Life Science
-featured.png)
This course explores core biological ideas: homeostasis and feedback mechanisms, natural selection and its supporting evidence, biotechnology applications and ethical considerations, and population dynamics including carrying capacity. Through examples and case studies, learners will explain physiological balance, analyze evolutionary data, evaluate the impacts of biotechnological tools, and assess ecosystem limits—preparing high-school or introductory college students and curious adults to think critically about life sciences.

What you'll learn
- Describe homeostasis as a fundamental state of balance among all body systems in humans, identifying key indicators such as body temperature, glucose level, and blood pressure.
- Explain how homeostasis is actively maintained through various biological control systems, specifically distinguishing and describing the function of positive and negative feedback mechanisms.
- Use information from secondary sources to describe natural selection as the primary mechanism driving evolutionary change and discuss key related concepts such as variation, heredity, selection, and adaptation.
- Use information from secondary sources to explain how various lines of evidence—including the fossil record, biogeography, and comparative morphology—support the occurrence of biological evolution.
- Explain the term biotechnology, provide examples of both traditional (e.g., fermentation products) and modern applications (e.g., GMOs), and debate the societal, environmental, and ethical implications of using biotechnological methods.
- Discuss the factors (such as food, shelter, and water) that limit an ecosystem’s carrying capacity and explain that the ecosystem’s population growth slows down as it approaches this maximum limit.
